Description

Acid ester alkylene succinic acid and ethylene glycol. Polyoxyethylene aliphatic acids

With a degree

16oxyethylation of 100.02-0.1 Water or. mineral oilUntil 100 Product a is obtained on the basis of synthetic fatty acids of the CQ - fraction obtained by the oxidation of solid hydrocarbons. Based on this fraction of acids, primary amines are synthesized, which are then oxyethylated.
