Abstract
A process for the catalytic or non-catalytic esterification of acids or anhydrides with a mono-alcohol or a polyhydroxy compound which comprises the steps of adding the reagents to a reaction vessel to form a reaction mixture, and heating the reaction mixture and maintaining a pressure sufficient to obtain boiling of the reaction mixture thereby causing esterification and removing water as vapor while continuously mixing the reaction mixture in the reactor vessel such that at least about 2.5 to about 20 volumes of reaction mixture are internally recirculated per minute, whereby the rate of conversion is enhanced.
Claims28
A process for the esterification of acids or anhydrides with a mono-alcohol or a polyhydroxy compound which comprises the following steps:
- a. adding either an acid or anhydride and a mono-alcohol or a polyhydroxy compound to a reaction vessel to form a reaction mixture;
- and
- b. heating said reaction mixture and maintaining a pressure sufficient to obtain boiling of said reaction mixture thereby converting said acid or anhydride to an ester and removing water as vapor while continuously mixing said reaction mixture in said reactor vessel such that at least about 2.5 volumes of reaction mixture are internally recirculated per minute, whereby the rate of conversion is enhanced.
