Process for production of ester compounds.

摘要

In producing ester compunds useful as an antixidant for organic materials which are reperesented by the formula: <CHEM> , wherein R<1> and R<2> are the same or different hydrogen or straight or branched chain alkyl radicals containing 1 - 8 carbon atoms, Z is an organic radical derived from an n-hydroxy alcohol, and n denotes an integer of 1 to 4, by the transesterification, monoalkyltin compounds are used as a catalyst, whereby the ester compounds can be produced with high quality and in high yields.
