ABSTRACT:
Disclosed is a process for the preparation of 3-methyltetrahydrofuran (3-MeTHF) from 3-(hydroxymethyl)tetrahydrofuran (3-HOMeTHF) by a plurality of process steps comprising (1) esterifying 3-HOMeTHF to produce a carboxylate ester of 3-HOMeTHF, (2) pyrrolyzing the carboxylate ester to produce 3-methylenetetrahydrofuran (3-methyleneTHF), and (3) hydrogenating the 3-methyleneTHF to produce 3-MeTHF. The 3-MeTHF produced in accordance with the present invention is useful as an industrial solvent and as a monomer in the manufacture of polymers such as elastomers.
