Studying the effect of process parameters on the epoxidation of propylene in a methanol medium in the presence of extruded titanium silicate

Abstract

Quantitative data on the effect of process parameters on the main features of the liquid-phase epoxidation of propylene with an aqueous solution of hydrogen peroxide in the presence of extruded titanium silicate in a methanol medium are obtained. The effect of the solvent concentration (13.7–19.1 mol/L), the initial propylene: hydrogen peroxide ratio ((2–5) : 1), and the temperature (30–60°C) on the yield of the target product (propylene oxide) and such byproducts as 1,2-propyleneglycol, 1-methoxy-2-propanol, and 2-methoxy-1-propanol, is studied. The observed characteristics are used as a basis for recommendations concerning the conditions of propylene oxide synthesis in a continuous laboratory setup.
