| titleOfInvention | Method for producing sulfolane compound |
| abstract | (57) [Summary] [Objective] A method for producing a sulfolane compound effective for removing unreacted sulfur dioxide and reducing production of a sulfone polymer. (1) contacting the conjugated gen with sulfur dioxide under conditions sufficient to synthesize the sulfolene compound to produce a mixture of impurities containing the sulfolene compound and unreacted sulfur dioxide, (2) The mixture is heated to about 55 ° C At a temperature in the range of about 85 ° C., it is transferred to an impurity removal reactor containing a solvent, and (3) an impurity-reduced sulfolene compound is produced under high pressure to produce an impurity-reduced sulfolene compound. The purified sulfolene compound is transferred to a hydrogenation reactor, and (5) the pure sulfolene compound having reduced impurities is treated with hydrogen under the conditions sufficient to produce a sulfolane compound in the presence of a hydrogenation catalyst. A method for producing a sulfolane compound, which comprises contacting and (6) optionally recovering the sulfolane compound. |
