News of Chinese Phosphate Ore Market (November 8, 2017)
2017-11-14

  Recently, the price of Chinese phosphate ore increased substantially, the overall increase of price was 30-60 yuan/ton according to the current main factory quotation of 30% grade phosphate ore and 32% grade phosphate ore, both origined Guizhou province, the overall price increase of Yunnan province origined ore was 10-30 yuan/ton. Started from November, the Chinese phosphorus ore market was stable and then rising. Factors affecting the upward trend of the phosphate ore market in November are as follows:   1. Demand In October, the downstream of the yellow phosphorus market had a sharp rise of about 40%, which made the operating rate of yellow phosphorus reached about 60%. The recovery of yellow phosphorus has been increased since November: the operating rate reached 90%, the demand for upstream phosphorus ore is increasing, and the downstream dealers have strong desire to store goods, so the demand for phosphate ores is strong.   2. Supply The limited mining of upstream ore led to a decline in the operating rate of phosphate ore producers, tight shipment and insufficient supply. The market price is looking rise, and the specific market trends also depend on downstream demand and market supply.

The Use of L-theanine In Beverages
2017-11-05

L-theanine, or tea amino acid, a special amino acid found only in green tea, is become a new heat in beverages. In the past couple years, it appeared more frequently and also in a sizeable quantity in beverages like soft and sports drinks. These drinks claim benefits like energy boost, focus improvement and stress release, and suitable for people who doesn’t like or couldn’t take caffeine. Till the end of November 2016, beverage containing l-theanine was triple compared to 2012. However, only small amount of leading brands specified that their products contain l-theanine, for example, Lipton’s black tea. Instant tea is the main battlefield of l-theanine, while sports and energy drinks containing l-theanine is sharply increased in 2016, to be exact, a 9% of total amount of sports and energy drinks, which is also the history highest point.     Matcha contains high level of l-theanine and makes itself promising in the new market. Two famous beverage brand in Sweden made good use of l-theanine. Swedish is the top consumer of caffeine among all countries, as the grand base, a great amount of people are willing to try replacement or counterpart of caffeine. In 2015, each Swedish person consumed 9 kilograms of coffee, which is double of the U.S. Swedish beverage company launched a juice with high content of l-theanine, which is equivalent to 15 cups of tea. The company claimed that the innovative juice helps people to release stress and keep focus, which could compete and defeat the benefits of caffeine. Although the total product count of l-theanine is not huge at present, the number is increasing globally. More and more consumers are looking for beverages and drinks with functions of refresh and focus. L-theanine could fit these needs and possibly will be a new trend and market highlight.

List of strong acids
2017-10-25

In our daily life, we cannot live without chemicals. In theory, all the chemical compounds have alkalinity or acidity. So you may wonder what are the strong acids and weak acids, strong bases and weak bases. Strong acids and the list of strong acids The ionization constant of acid in aqueous solution is the standard of the strong acid now. In general, the pKa of the strong acid (the acidity coefficient, the negative log of the ionization constant) is less than 1. Strong acids mainly refer to permanganic acid, hydrochloric acid (hydrochloric acid), sulfuric acid, nitric acid, perchloric acid, selenoic acid, hydrobromic acid, hydroiodic acid, and chloric acid. They all can lead to severe stimulation and corrosion, and can cause serious burns when contacting to the body and should be washed with water or soda. But it's quite interesting that carbon borane acid, the strongest super acid, is not corrosive and can be held in your hand! Inorganic strong solids include: Sulfuric acid (H2SO4), nitric acid (HNO3), perchlorate (HClO4), hydrochloric acid (HCl), hydrobromic acid and hydroiodic acid (HI), high bromate (HBrO4), chlorate (HClO3), bromate (HBrO3), fluosilicate (H2SiF6), chlorine lead-acid (H2PbCl6), partial (HPO3), osmic acid phosphate, permanganate (HMnO4), selenium acid (H2SeO4), high-speed acid (H2FeO4), fluoboric acid (HBF4), fluoride sulfonic acid (HSO3F), cyanate (HOCN), thiocyanate (HSCN), high iodate (HIO4). Organic strong acids include: 2,4,6-trinitrobenzoic acid , trifluoroacetic acid (TFA, CF3COOH), trichloroacetic acid (CH3SO3H), benzenesulfonic acid (C6H5SO3H), KMD acid (cyclohexanethiol sulfonic acid), 2-chloroethanethiol (CH3CHClSH, generally regarded as strong acid). And here is a part of the super acid list:  Antimony fluoride sulfonic acid (SbF6SO3H), perfluorinated sulfonic acid resin, chlorine, fluorine aluminate (HAlCl3F, including complex ion AlCl3F-), carbon borane acid, solid super acid, such as FeCl3 · HClO4, SiO2 · nH2O. Weak acids and the list of weak acids The pKa of the strong acid (the acidity coefficient, the negative log of the ionization constant) is more than 4. Weak acids can not completely ionize in solution. If you use the usual HA to indicate the acid, there is still a good amount of HA in the solution in addition to ionizing the proton H+ in the aqueous solution. Here is the formula: HA(aq)↔H+(aq)+A-(aq). When the solution is in equilibrium, the relationship between reactants and prod ucts can be expressed as follows: Ka=[H+][A-]/[HA]. The larger the Ka (or the smaller the pKa value) is, the more hydrogen ions (H+) are formed, and the smaller the pH will be. Except for a few acids that are defined as strong acids or super strong acids, most of the acids are weak acids. Organic acid is also an important part of weak acid. Common household weak organic acids include acetic acid in vinegar, lemons and citric acid in many raw fruits, inorganic acid such as boric acid used as an antimicrobial agent, and the carbonic acid used in sodas. Common weak acids are like H2SiO3, HCN, H2CO3, HF, CH3COOH, H2S, HClO, HNO2, H2SO3 and so on. Strong bases and the list of strong bases A strong base usually refers to a substance that can change the color of a particular indicator, in a standard case (with a concentration of 0.1 mol/L) and a pH of more than 7. All ions ionized in aqueous solutions are hydroxide ions, which react with acids to form salts and water. The so-called strong base and weak base are relative---- alkali dissolved in water can completely disassociate belongs to strong base. Strong alkali is divided into organic strong base and inorganic strong base. Alkali is highly corrosive. In organic strong alkali, organic metal compounds are the most alkaline, such as organic metal lithium compounds (such as butyl lithium, diisopropyl ammonium lithium, benzyl lithium, etc.), grignard reagent, alkyl copper lithium, etc. In inorganic strong alkali, amino compounds (such as amino potassium, amino sodium) and alkali metal hydride (NaH, KH, etc.) are the most alkaline, and then the following is hydroxide. Alkaline metals and some alkaline-earth metals are usually strong bases, too. Alkali metal hydroxides are like LiOH, NaOH, KOH, RbOH, CsOH, FrOH. Alkaline earth metal hydroxides are like Ca(OH)2, Sr(OH)2, Ba(OH)2, Ra(OH)2. Other strong alkalis are like Hg(OH)2, TlOH, Tl(OH)3, AgOH·2NH3, HOCH2CH2N(CH3)3(OH). Weak bases and the list of weak bases A weak base is a base that is not completely ionized after water, which means that the proton reaction of it is incomplete. The pH of the weak base is greater than 7 but closer to 7. Compared with strong base, the weak base is less able to accept the proton from the water molecule, so the H+ concentration in the solution is higher and the pH value is lower. Weak base is not necessarily insoluble in water, for example, NH3·H2O is easily soluble in water, but it is not completely ionized in water, so NH3·H2O belongs to weak base. A base that cannot be completely ionized in solution is usually formed by a non-reactive metal (or NH3), such as Al(OH)3, Cu(OH)2, Fe(OH)2, Fe(OH)3, Zn(OH)2and other insoluble bases. Here is a part of the list of weak bases: NH3·H2O, aluminum hydroxide: Al(OH)3, Cu(OH)2, Fe(OH)2, Fe(OH)3, zinc hydroxide: Zn(OH)2, AgOH and so on.   If you are interested in them, click here and get more information on okchem.com!

Folate vs Folic Acid
2017-10-25

Folate is one of the B vitamins and also a water-soluble vitamin. The daily intake of folate from foods or dietary supplements is recommended 400 micrograms according to the US. The study shows that folic acid is particularly important for women during pregnancy. Folic acid is used as a supplement to prevent neural tube defects in the baby. Folic acid can promote the maturation of bone marrow cells, folic acid deficiency can cause megaloblastic anaemia and leukopenia. There are many foods that contain folic acid, but the natural folic acid is very unstable and easy to be affected by the sun and heating to oxidation. So the folic acid absorption by human body from food is not much. The bioavailability of folic acid is low, which is about 45%. The synthesis of folic acid can keep stable in a period of months or years, and can be easily absorbed and utilized by human body. The biological factor was first isolated via extraction from spinach leaves in 1941, therefore it was named folic acid. This vitamin B9 is rich in fresh fruits, vegetables, and meat products. 50% to 90% folic acid may be lost during long time of food cooking. The absorption is mainly in duodenum and proximal jejunum. Its storage in human body is 5 ~ 20mg. Folic acid is excreted mainly through urine and feces, and the daily output is 2 - 5ug. MTHFR is an important enzyme involved in the cyclic metabolism of folic acid. It is related to the synthesis of methylation in DNA. This B vitamin is an indispensable component of cell division and synthesis of DNA. In 60s, researchers did animal experiments and found that folic acid deficiency could cause neural tube defects. Therefore, MTHFR gene detection can guide pregnant women to reasonably supplement folic acid, and prevent cleft lip and palate, down syndrome, neural tube defects and other birth defects. It suitable for normal couples of prenatal testing. Folic acid has become a new health vitamin product on the international market after vitamin C and vitamin E, and its market prospect is very broad. Iron folic acid is one of these products.

Main use of food grade bentonite clay Food grade bentonite clay is made of high quality bentonite bulk through sodium modification, washing and purification of refined production process. It’s milky white, tasteless powder. Food grade bentonite clay is used as adsorbent, filter aid, clarifier and bleaching agent, in wine, fruit and vegetable juice, tea drinks, etc. Food grade bentonite clay adsorbs, wraps and precipitates the residue, protein and fine impurities in the wine and juice. How food grade bentonite clay works Food grade bentonite clay has a unique crystal structure. Because of this structure, it has a large surface area, strong expansion, adsorption and decolorization. The expansibility and negative charge of food grade bentonite clay can effectively adsorb suspended particulates like proteins, pigments and other positive charge. Bentonite clay resources Bentonite clay resources are mainly distributed in China, the United States, Russia, Greece, Turkey, Germany, Uk, Canada, Australia and other countries. China, the United States and Russia have 75% of global bentonite reserves. Calcium bentonite is world-wide distributed, but sodium bentonite is relatively rare. However, food grade sodium bentonite is much more superior in properties than calcium bentonite clay food grade. China has rich bentonite resources, with total reserves of 2.46 billion tons. Sodium bentonite and calcium bentonite account for about 27% and 31% of the total reserves respectively. The rest are aluminum bentonite and hydrogen bentonite. Speaking of food grade sodium bentonite clay, it’s also the most used kind of bentonite clay in food and beverage industry. Sodium bentonite reserves in China, is about 586.343 million tons. Where to buy food grade bentonite clay There are 43 large and medium - sized deposits in China. Most of them are are distributed in Inner Mongolia, Xinjiang, Zhejiang, and other provinces. Linan, Zhejiang has found the first large sodium bentonite deposit. OKCHEM provides best sourcing service in chemical industry. Visit www.okchem.com for more info.
