Production of tetrahydrofuran from 1,4-butanediol
Provided is a method for the production of tetrahydrofuran (THF) from 1,4-butanediol (BDO) using a zirconium sulfate (Zr(SO 4 ) 2 .nH 2 O) catalyst. The method of the present invention can achieve high-yield production of tetrahydrofuran via a simple and low-risk production process by dehydration of 1,4-butanediol in the presence of a zirconium sulfate catalyst.
1. A method for production of tetrahydrofuran (THF) from 1,4-butanediol (BDO) using a zirconium sulfate (Zr(SO 4 ) 2 .nH 2 O) 4 catalyst.
2. The method according to claim 1 , wherein a reaction temperature is in the range of 150 to 350° C.
3. The method according to claim 1 , wherein the zirconium sulfate catalyst is used alone or is supported on a carrier.
4. The method according to claim 1 , wherein the zirconium sulfate catalyst is pretreated at a temperature of 200 to 700° C. using an inert gas prior to reaction.
5. The method according to claim 3 , wherein the carrier of the zirconium sulfate catalyst is selected from the group consisting of alumina, silica, titania, zeolite and activated charcoal.
