CONTINUOUS PROCESS FOR THE CONVERSION OF 2,5-DIHYDROFURAN TO 2,3-DIHYDROFURAN

摘要

Disclosed is a process for the continuous production and recovery of 2, 3-dihydrofuran (2,3-DHF) by the isomerization of 2,5- dihydrofuran (2,5- DHF) which contains certain impurities to 2,3- dihydrofuran in yields exceeding 95%. The process utilizes, in order, an isomerization zone containing one or more beds of a supported, palladium or platinum catalyst, a product recovery zone comprising a distillation column, a high boiler removal zone and means for feeding the 2,5-DHF component of the bottoms stream from the product recovery zone to the isomerization zone.
