Ti-rich TS-1: A highly active catalyst for epoxidation of methallyl chloride to 2-methyl epichlorohydrin

Ti-rich TS-1 showed high catalytic activity and H2O2 efficiency for epoxidation of methallyl chloride (MAC). Unexpectedly, it was much more active in tert-butyl alcohol (TBA) solvent than in methanol and acetonitrile partially because TBA increased the adsorption amount of MAC in the channel of Ti-rich TS-1, and consequently enhanced the MAC concentration around the Ti sites. By optimizing reaction conditions, the MAC conversion reached 85.4% with epoxide selectivity of 96.7%, which could be maintained by regenerating the catalyst by calcination. Addition of alkali or salt into the reaction system or impregnation of these materials on the Ti-rich TS-1 led to a drastic decrease in activity. In combination with NH3-TPD and diffuse reflectance UV-vis spectroscopy results, it was found that active Ti-OOH (η2) intermediates were formed for framework tetrahedral Ti species with moderately strong Br?nsted acidity. This indicates that an Eley-Rideal-type reaction mechanism probably dominated the MAC epoxidation over Ti-rich TS-1.

Optimization of the technological parameters of epoxidation of methallyl chloride by hydrogen peroxide over TS-1 catalyst

The influence of the technological parameters on the course of epoxidation of methallyl chloride by a 30 wt % hydrogen peroxide over the titanium silicalite TS-1 catalyst has been investigated. The effects of temperature, molar ratio of methallyl chloride to hydrogen peroxide, concentrations of methanol (solvent) and TS-1 catalyst, and reaction time were determined. The optimisation of the technological parameters of methallyl chloride epoxidation was performed by the application of a statistical experimental design method based on a rotatable uniform design. The epoxidation process was described by using the following functions: the selectivity of transformation to 2-methylepichlorohydrin in relation to methallyl chloride consumed, the selectivity of transformation to organic compounds in relation to hydrogen peroxide consumed, the conversions of methallyl chloride and hydrogen peroxide.
