KINETICS OF 2-HEXANOL AND 3-HEXANOL OXIDATION REACTION OVER TS-1 CATALYSTS

A kinetic investigation of the catalytic oxidation of 2-(3-) hexanols to 2-(3-) hexanones over a series of titanium silicalites [TS-1] is re ported. This study considers the biphasic character of the reaction me dium and uses the mathematical theory of linens graphs to derive rare equations for both hexanols' oxidation and hydrogen peroxide's decompo sition. The 2-hexanols' oxidation is usually considered as the seconda ry reaction in the n-hexane oxyfunctionalization process. Comparing th e kinetic constants obtained in this study and those generated by the analysis of previously published n-hexane oxyfunctionalization rate da ta allows one to conclude that in the latter case, hexanones are also produced by a direct primary oxidation of n-hexane.
