| Abstract: | Limonene oxide is an intermediate getting growing attention in industrial chemistry. A series of Ti‐MCM‐41 heterogeneous catalysts with different hydrophilic/hydrophobic character, prepared by post‐synthesis silylation with hexamethyldisilazane (HMDS), were studied in the liquid‐phase epoxidation of limonene with tert‐butylhydroperoxide (TBHP). A maximum yield of 84 % in limonene oxide was obtained over a partially silylated catalyst with a surface coverage of 55 %. |
