Abstract
A process for the continuous hydrolysis of esters containing from 2 to about 16 carbon atoms to form at least one alcohol and at least one carboxylic acid and the concurrent separation of the hydrolysis products has been developed. The process uses a solid bed which acts as a catalyst for hydrolysis and as an adsorbent for at least one class of the products. The process operates in the simulated moving bed mode. A specific embodiment of the invention is one where the simulated moving bed is a homogeneous mixture of at least one solid effective as a hydrolysis catalyst and at least one solid effective as an alcohol or carboxylic acid adsorbent. Another specific embodiment is one where the simulated moving bed is a strongly acidic macroreticular polymeric resin effective both as a hydrolysis catalyst and as an adsorbent for at least one hydrolysis product.
