Methods of tetrahydrofuran

Industrial production of the earliest sugar aldehyde as raw material, the mixture of sugar aldehyde and steam through the reactor filled with zinc - chromium - manganese metal oxide (or palladium) catalyst, carbonyl removal at 400-420℃ to form furan; Tetrahydrofuran was prepared by hydrogenation of furan at 80-120℃ using skeleton nickel as catalyst. To produce 1 ton of TETRAhydrofuran by this method, about 3 tons of polysaccharide aldehydes are consumed. Later, there are many kinds of production methods of Chemicalbook exhibition. The industrialized method has 1, 4-butanediol catalytic dehydration ring method, because butanediol is made of acetylene and formaldehyde, this method is called Reppe method; Using chloroprene monomer chlorbutadiene by-product 1, 4-dichlorobutene production of tetrahydrofuran, known as dichlorobutene method; In recent years, catalytic hydrogenation using maleic anhydride as raw material has been developed.

APPLICATION of tetrahydrofuran
