PROCESS FOR PREPARING AND PURIFYING COMPLEX ESTERS |
摘要 |
The invention concerns a process for manufacturing polyol complex esters. According to the method, a polyol, such as BEPD or NPG, is reacted with mono- and polyvalent acids in the presence of a catalyst to produce a reaction blend containing complex esters. According to the invention the acid components of the reaction blend are neutralized with a tertiary amine, and the complex esters are recovered from the thus treated reaction blend. The basic amines that are used form salt-like compounds with the carboxylic acids. The compounds enter the aqueous phase, from which they are easily separated, whereby the complex esters are recovered with high yield.
