p-Chloronitrobenzene is obtained together with o-chloronitrobenzene and m-chloronitrobenzene by nitration of chlorobenzene and is then purified by extractive crystallization.
ortho-Vanillin (2-Hydroxy-3-methoxybenzaldehyde) is an organic solid present in the extracts and essential oils of many plants. Its functional groups include aldehyde, ether and phenol. It is distinctly different from its more prevalent isomer, vanillin. ortho-Vanillin is a fibrous, light-yellow, crystalline solid. Unlike its better-known analogue, o-vanillin does not have the characteristic and intense odor of vanilla. Present in a variety of food products, it is not specifically sought after, and is therefore a less-commonly produced and encountered food additive.
HQEE is off-white flakes and powder. It has a melting point of 102 and an auto-ignition temperature of 467.
HQEE is hygroscopic and should be stored in a cool dry place. To help prevent moisture absorption, desiccant agent is included in the drum. It is important that the drum and inner bag be resealed if only part of the HQEE is used. HQEE is also sensitive to light (UV) and will turn yellow or brown in the presence of light.
M-CDEA is a derivative of the MDA class, able to be combined with TDI prepolymer to prepare for PU elastomers with excellent performance. Mixed with corresponding MOCA or 740M for use, the property of PU elastomers can be improved, reflecting good additive effects. It has been widely used in PU pouring, spraying, RIM and other technical methods, as well as microporous products, TPU, adhesive, coating agent and other preparation of products. This product has low toxicity.
Zinc oxide is an inorganic compound with the formula ZnO. It is a white powder that is insoluble in water, and it is widely used as an additive in numerous materials and products including rubbers, plastics, ceramics, glass, cement, lubricants, paints, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, and first-aid tapes. Although it occurs naturally as the mineral zincite, most zinc oxide is produced synthetically.
