General Product
Basic Description
Pentaerythritol is a kind of white crystalline powder, slowly soluble in cold water, soluble in hot water, insoluble in carbon tetrachloride, ethyl ether, benzene, petroleum ether, ethanol, acetone, solubility in water, methanol, ethanol, butylamine, dimethyl sulfoxide, ethanolamine . Pentaerythritol will polymerize when heated to above melting point, and generates a shrinkage second shrinkage e four season three pentaerythritol, etc. Stability in the air. The hydroxyl groups of Pentaerythritol can form complex with many kinds of metal; Can directly react with nitric acid trough nitration; Under the effect of catalyst, the hydroxy can be oxidized to acid; Can react with chlorine to generate the chloride; In acid medium, the product react with carbonyl compounds, generate cyclic acetal and ketal; Like other alcohols, can esterify with an acid or anhydride to generate four ester; The halides can dehalogenate to generate cyclic ether in the role of alkali.
Main Property
Mainly used for resins, radiation curing monomers, polyurethanes, rosin esters, synthetic lubricants and pigment treatment. Used as charring agent in halogen-free intumescent coating, usually working together with ammonium polyphosphate and melamine.
Package & Storage
Package: 25kg/bag. Storage: Dry, ventilated, moisture-proofing.
