<p>PURPOSE:To obtain cyclohexanol and cyclohexanone at a high selectivity, by oxidizing cyclohexane with an oxygen-containing gas in the lquid phase in the presence of a salt of metals selected from the group consisting of Cr, V, and W of an organic acid or a chelate compound as a catalyst. CONSTITUTION:Cyclohexane is oxidized in the liquid phase with an oxygen-containing gas in the presence of a salt of metals selected from the group consisting of Cr, V, and W of an organic acid or a chelate compound as a catalyst. The first product cyclohexyl hydroperoxide is rapidly decomposed into cyclohexanol and cyclohexanone. Examples of the catalyst include chromium, vanadium, and tungsten naphthenates, and chromium acetylacetonate. The amount of the catalyst is preferably 0.1-20 ppm, more preferably 0.5-10ppm based on the cyclohexane of the metallic atom.</p> |
