Technologies Chemanol obtained proprietary-licensed technology for its new pentaerythritol facility from Swedish firm Perstrop AB, a world leader in the manufacturing of polyhydric
alcohols and other specialty chemicals.
21, 2008) as a combination of a polyhydric
alcohol (glycerol or glycol); an organic acid (adipic, citric, maleic, succinic, polyacrylic or some combination); and an anhydride (succinic, maleic, phthalic or some combination) together with any of a number of common fillers like talc or clay.
The cross-linked siloxane-polyurethane systems that have been reported were prepared by the crosslinking of Si-O-Si through a hydrolysis condensation process (7-8) or by the reaction of NCO and OH groups in the polymethane polyphenyl polyisocyanate and in the multifunctional polysiloxane polyols, respectively, (9) or by the incorporation of polyhydric
alcohols into the polyurethane formulation.
A variety of substances including proteins and polyhydric
alcohols have been proposed as agents preventing icenucleation in the hemolymph (Husby & Zachariassen 1980; Zachariassen 1985; Kirchner 1987).
Patented is a water-absorbent resin, which is surface-crosslinked with a surface-crosslinking agent including at least a polyhydric

The polyols are polyhydric
materials with high molecular weight resulting from the catalyzed polyaddition of propylene oxide and ethylene oxide to molecules like glycerin, sorbitol, or sucrose.
These include extractives such as the monoterpenes, sesquiterpenes, diterpenes (resin acids), other aromatics, and polyhydric
alcohols (Browning 1975).
Vegetable oil tranesterification with polyhydric
alcohols and the chemical structure of the synthesized products are widely covered in the literature.
Tokyo, Japan, Sept 22, 2005 - (JCNN) - Mitsubishi Gas Chemical and Mitsubishi Chemical have signed a basic agreement to establish a joint venture, Polyols Asia, for production and sales of polyhydric
alcohol (neopentyl glycol, trimethyrol propane, and ester glycol).
The drying oil is reacted with a polyhydric
alcohol like glycerol or pentaerythritol, forming polyol-modified vegetable oil or polyol-modified fatty acid.
However, it has been shown that the kinetics of enzymes can be changed by polyhydric
alcohols (25) and that aspartase is activated by glycerol, ethylene glycol (1,2-ethanediol), and propylene glycol (1,2-propanediol) (26).
