METHOD FOR PRODUCING TETRAHYDROTHIOPHENE

The invention relates to a method for producing tetrahydrothiophene, comprising a step of reacting 1,4-butanediol or tetrahydrothiophene, in the presence of hydrogen sulfide (H2S), and optionally carbon dioxide in the gas phase, at a temperature of between 200 and 320° C, in the presence of alumina...
