Pentaerythritol is also known as 2, 2-bis (hydroxymethyl)-1, 3-propylene glycol, tetramethylmethane, MetabAuxil,
Penetek. Tollens was first discovered in 1882.
The precipitate from dilute hydrochloric acid is a tetragonal colorless ditetrahedral crystal.
Relative molecular weight 136.15. Relative density 1.399.
Melting point 262 ℃ (industrial products containing 10% ~ 15% e four two shrinkage two season, melting point of
180 ~ 225 ℃).The boiling point of 276 ℃ (4.00 x 103 pa).The refractive index is 1.54 ~ 1.56.Can be sublimated.
Slowly soluble in cold water, soluble in hot water, insoluble in carbon tetrachloride, ethyl ether, benzene, petroleum ether,
ethanol, acetone, 25 ℃ when the solubility of (g / 100 g) : water, methanol, ethanol 0.75 7.23 0.33, butylamine 16,
dimethyl sulfoxide, ethanolamine 16.5 4.5.When pentaerythritol is heated above the melting point,
polymerization occurs, and dipentaerythritol are produced.Stable in air.

1.Pentaerythritol as a quaternary alcohol, easy esterification of acid and ester, so most of the alkyd resin coating materials,
mainly used as building coatings and automotive primer.
2.Industrial use of pentaerythritol with nitric acid in 5 ~ 15 ℃ esterification available pentaerythritol tetranitrate
(also known as PETN, too), is a kind of high performance high explosives, its bigger than TNT explosive,
much as a booster, or mix with TNT.It was used extensively in world war ii.
3.Pentaerythritol and rosin acid reaction can make pentaerythritol rosin ester, it and dry oil mixture can get a kind of paint,
its hardness, water resistance and weather resistance is better, used for varnish, floor ink.
