Process for producing sulfolane compounds |
摘要 |
A process for producing sulfolane compounds is provided which comprises: (1) contacting a conjugated diene with sulfur dioxide under conditions sufficient to synthesize a sulfolene compound whereby a mixture of the sulfolene compound and impurities comprising unreacted sulfur dioxide is produced; (2) transferring the mixture to an impurities removal vessel containing a freezing point depressant which comprises an aromatic compound; (3) removing the impurities; (4) transferring the impurities-reduced sulfolene compound to a hydrogenation reactor; (5) contacting the impurities-reduced sulfolene compound with hydrogen, in the presence of a hydrogenation catalyst, under conditions sufficient to produce a sulfolane compound; and (6) optionally recovering the sulfolane compound.
