Pentaerythritol and Dipentaerythritol

Product Description

PENTAERYTHRITOL:
Pentaerythritol is a kind of organic polyatomic. It is part of white crystal powder solid without poison and odor, which is stable in air, and without water sucking. Melting point 260 centigrade polymerization, sublimation under pressure reduction, dissolvedslightly in cold water but easliliy in hot water.
Usea of products:
Pentaerythritol is the main raw material of alkyd resin, oil painting and painting. It also can be used as follow: Manufacturing plastifiers that of hot and cold resistance and without poison, additive agent of lubricant, emulsifying agent, petroleum anti-freezing agent, stabilizing agent of polyvinyl chloride, chlorinated polythether, fire retardant, fire resistance painting and printing ink and the like. Tetranotro-penraerythritol, which is a kind of high expolsive, produced after the chemical reaction with nitric acid.

DIPENTAERYTHRITOL:
Di-PE is a white, odor less and crystalline powder. It is no poison to animal, no stimu-late to skin, no pollution to environment. Puritys melting point 221-22.5. Di-PE is slightly soluble in water, but little soluble in most organic solvent.

Application
Di-PE, as an important fine-chemical intermediate, it is mainly used in used in the manufacture of plasticizers, lubricants, waxes and fire-retardant composition.
