PROCESS FOR PRODUCTION OF METHYLTETRAHYDROPHTHALIC ANHYDRIDE

摘要

This invention provides a process for producing methyltetrahydrophthalic anhydride characterized in that maleic anhydride and a C5 fraction are subjected to Diels-Alder reaction in the presence of a radical polymerization inhibitor and oxygen. According to the process of this invention, formation of gels as byproduct is substantially completely inhibited.
