PROCESS FOR PRODUCING OF TETRAHYDROFURAN FROM 1,4-BUTANEDIOL

摘要

A tetrahydrofuran is provided to be manufactured from 1,4-butanediol with a reaction yield using a simple impartiality having less risk. A tetrahydrofuran is manufactured by dehydrating 1,4-butanediol under presence of iron phosphate catalyst. A dehydrating temperature is 150~300°C. An iron phosphate catalyst is used independently or by being supported using carrier. The iron phosphate catalyst is pre-processed at a temperature of 200~400°C by using inert gas before the reaction.
