Di-pentaerythritol
Molecular formula:
Molecular weight:
Characteristics:
Di -PE is a white ,odorless and
crystalline powder. It is no poison to animal. no stimulate to skin, no
pollution to environment .Purity's melting point 221-222.5°C. Di-PE is slightly
soluble in water, but little soluble in most organic solvent. It can react with
organic material and turn into ester. Di-PE usually consists of a little mono-PE
and Tri-PE .So its hydroxyl value is between 38-40.
.

Application:
Di-PE, as an important
fine-chemical intermediate, it is mainly used in coating industry, polyether,
alkyd resin photosensitive resin film. Its low aliphatic ester is used
as PVC plasticizer in hi-temp insulating material .Its high aliphatic ester is
in aviation lubricant.
