Title:

PROCESS FOR PRODUCING METHYLTETRAHYDROPHTHALIC ANHYDRIDE

Document Type and Number:

WIPO Patent Application WO/1989/000564

Kind Code:

A1

Abstract:

A process for producing methyltetrahydrophthalic anhydride, which comprises subjecting maleic anhydride and a C5 fraction to Diels-Alder reaction in the presence of a radical polymerization initiator and oxygen. This process enables substantially complete inhibition of the formation of a gel-like by-product.
