Selective oxidation of n-hexane over a titanium silicate molecular sieve with MEL structure

Abstract

The selective oxidation of n-hexane to secondary alcohols and ketones has been carried out with hydrogen peroxide using TS-2, a titanium silicate molecular sieve, as the catalyst. TS-2 is found to be highly selective in the oxidation of alkanes. The infhrence of various parameters, such as the Ti/(Si+Ti) ratio of TS-2, its concentration, the temperature of the reaction, the feed ratio (n-Cs:H,02), the nature of the solvent and the substrate (reactant) size and shape, on the activity and selectivity in the oxyfunctionahiation reaction are reported.
