Chemie und Industrie
Verwendung und Herstellung
Methods of Manufacturing
The common esters & diesters of the common polyols are prepared commercially by esterifying the particular polyol with the acid, acid anhydride, or acid chloride of choice in presence of a catalyst. Mono- or diesters result, depending upon the proportions of each reactant employed. /Esters, diesters, & ether--esters of glycols/
