Kind Code:
B2
Abstract:
PCT No. PCT/EP91/01050 Sec. 371 Date Dec. 15, 1992 Sec. 102(e) Date Dec. 15, 1992 PCT Filed Jun. 6, 1991 PCT Pub. No. WO91/19559 PCT Pub. Date Dec. 26, 1991.Process for carrying out an equilibrium reaction in which one or more products are separated off by vapor permeation comprising the steps of: A) forming a reaction mixture comprising the reactants to be reacted in at least one reaction zone at a reaction temperature and reaction pressure selected so as to provide a reaction temperature above the boiling temperature of at least the product or products to be removed, wherein at least the product or products to be removed enters the resulting vapor phase in vapor form; B) passing the vapor phase containing the product or products to be removed to a zone remote from the reaction zone, which remote zone contains a semi-permeable membrane permeable to the product or products to be removed; C) carrying out vapor permeation in said remote zone to remove at least a portion of the product or products to be removed from said vapor phase; and D) returning the resulting vapor retentate from step C) to a reaction zone in step A). The process is especially useful in carrying out esterification reaction between a carboxylic acid and an alcohol.
