Claims
- 1. An improved process for the hydrolysis of esters wherein the improvement comprises contacting said esters with a catalytic composition comprising a perfluorinated ion-exchange polymer containing sulfonic acid groups supported on an inert carrier wherein said carrier comprises calcined shot coke and has a hydrophobic surface with a mean pore diameter of at least 1000 .ANG.; at a temperature of from about 130.degree. C. to about 180.degree. C.
- 2. The process of claim 1 wherein the ester is selected from the group monomethyl adipate, dimethyl adipate, monomethyl gluterate of dimethyl gluterate.
- 3. The process of claim 2 wherein the ester is dimethyl adipate.
