过氧化氢异丙苯分解绿色工艺 ?I.催化剂性能

对不同类型磺酸树脂催化剂进行比较，筛选出活性较高的磺酸树脂CT–175，用于过氧化氢异丙苯(CHP)分解工艺. 湿基树脂催化剂可采用丙酮脱水, 液固比为40 ml/g时, 经80 min, 脱水率接近100%. 研究表明，机械搅拌对树脂催化剂破碎有很大的影响，因此，反应器中不宜有机械搅拌装置. 另外，树脂催化活性与其在反应过程中吸附的Na+含量有重要关系，当树脂中Na+含量达到0.03%(w)时，需要再生. 适宜的再生条件是常温、3.5%(w)硫酸水溶液，可使Na+脱除95%.

Decomposition of Cumene Hydroperoxide Catalyzed by Resin Catalysts

Comparing different sulfonic resin catalysts, it was found that CT-175 has a higher activity and is suitable catalyst for the decomposition of cumene hydroperoxide. After the wet resin is dipped in acetone for more than 80 min, nearly 100% water can be removed when the ratio of acetone to resin is 40 ml/g. The main reason of resin fragmentation is mechanical stirring, so it is not suited for a reactor with a mechanical stirrer. The deactivation of resin is caused by Na+ in the resin, and the deactivated catalyst must be regenerated after the Na+ concentration is more than 3%. The optimal regeneration condition is room temperature and 3.5% (() H2SO4 solution by which more than 95% Na+ in the resin can be removed.
