The results of a study on the epoxidation of 1,5,9-cyclododecatriene (CDT) on a W-SBA-15 catalyst using the batch and half-periodic methods are presented. During this study, the activity of the W-SBA-15 catalyst was compared to that of the Ti-SBA-15 catalyst, and the W-SBA-15 catalyst was found to be about 20 times more active than the Ti-SBA-15 catalyst. The highest CDT conversion so far, amounting to 86 mol%, was obtained after carrying out the 4 h epoxidation process. Conducting the studied process using the semi-batch method did not result in the significant improvement in value functions describing this process (CDT conversion and selectivity of CDT transformation to ECDD), but the fastest HO dosing rate (246 µL/h) allowed us to obtain 9 mol% higher CDT conversion in comparison to the batch method.
研究了使用间歇和半间歇方法在 W-SBA-15 催化剂上使 1,5,9-环十二碳三烯(CDT)环氧化的结果。在这项研究中,比较了 W-SBA-15 催化剂和 Ti-SBA-15 催化剂的活性,发现 W-SBA-15 催化剂比 Ti-SBA-15 催化剂活性高约 20 倍。进行 4 小时环氧化过程后,获得了迄今为止最高的 CDT 转化率,达到 86mol%。使用半间歇法进行研究过程并没有导致描述该过程的价值函数(CDT 转化率和 CDT 转化为 ECDD 的选择性)有显著改善,但最快的 HO 剂量率(246 µL/h)使我们获得了比间歇法高 9mol%的 CDT 转化率。
