Abstract

1 min read

This chapter presents new hydrophobic Ti-Beta catalyst obtained by silylation and its catalytic performance for olefin epoxidation. Silylated Ti-Beta materials show a superior selectivity for epoxidation reactions than analogous fluoride synthesized Ti-Beta. This enhanced yield to the desired epoxide is attributed to the synergetic effect of the basic amine adsorbed on the Ti sites and the presence of silyl groups anchored on the silanol or titanol groups of the precursor Ti-Beta catalyst, which prevents the oxirane-ring opening reaction.
