2-ethyl-1-hexanol, n-heptanol, and n-hexanol oxidation by potassium permanganate was carried out in a baffled stirred reactor under heterogeneous conditions using phase transfer techniques. Tricaprylylmethylammonium chloride (Aliquat 336) was employed as the phase transfer catalyst. Kinetics of the oxidation was investigated. The rate constants were determined by varying the concentration of the catalyst, the concentration of alcohols and temperature. The rate constants agree well with those obtained under homogeneous conditions for all the three alcohols. The variation in the values under heterogeneous conditions were found to be less than 6 %.
