Transesterification of carboxylic or carbonic esters |
| abstract |
A process for the transesterification of a carboxylic or carbonic acid ester comprises reacting the carboxylic or carbonic acid ester under transesterification conditions with an alcohol in the presence, as catalyst, of either (i) a Group V element-containing Lewis base and an epoxide or (ii) a cyclic amidine. n The Lewis base can be an organic compound containing trivalent phosphorus or nitrogen and can be an amine, for example an amidine. n The process can be operated in the liquid phase at a temperature of from 15° to 150° C., and the catalyst is employed in solution. n Preferred catalysts are those where the cyclic amidine forms part of a fused ring system containing six and five membered rings, six and seven membered rings or two six membered rings. |
