CARBOXYLIC ACID ACCELERATED FORMATION OF DIESTERS

摘要

This invention pertains to accelerating the rate of formation of 1,1-dicarboxylic esters from the reaction of an aldehyde with a carboxylic acid anhydride or a ketene in the presence of a non-iodide containing a strong Bronsted acid catalyst by the addition of a carboxylic acid at one bar (100 kPa) pressure and between 0 and 80 DEG C in the substantial absence of a hydrogenation or carbonylation catalyst.
