W-SBA-15 as an Effective Catalyst for the Epoxidation of 1,5,9-Cyclododecatriene

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 H2O2 dosing rate (246 mu L/h) allowed us to obtain 9 mol% higher CDT conversion in comparison to the batch method.

Automated summary

The study compared the activity of W-SBA-15 catalyst to Ti-SBA-15 catalyst in the epoxidation of 1,5,9-cyclododecatriene (CDT). It was found that W-SBA-15 catalyst was 20 times more active than Ti-SBA-15 catalyst. The highest CDT conversion achieved was 86 mol% after a 4-hour epoxidation process. Using the semi-batch method did not significantly improve the value functions of the process, but a faster H2O2 dosing rate resulted in a 9 mol% higher CDT conversion compared to the batch method.
