Procedure
Except that 0.166 g (1.0 mmol) of 4-t-butylcatechol was used instead of 0.186 g (1.0 mmol) of ferrocene used in manufacturing of sulfolene, a 3-sulfolene aqueous solution was prepared in the same manner as in Example 1. The amount of 3-sulfolene in the obtained aqueous solution was 87 g (0.75 mol) and the yield from 1,3-butadiene was 75%. An amount of 3.8 g of polymers was found on the filter paper after filtering the 3-sulfolene aqueous solution. Next, the obtained 3-sulfolene aqueous solution was hydrogenated in the same manner as in Example 1. The reaction time was 70 minutes and the reaction was 100% progressed. Table 1 shows the measurements of the amount of generated polymers and the reaction time of hydrogenation.
