Abstract

Phenol is produced from a crude oxygenated cyclohexane fraction containing cyclohexanone and/or cyclohexanol and other cyclohexane oxidation products, the total amount of cyclohexanone and cyclohexanol being not over 95% by weight of the fraction, by vaporizing the fraction, diluting it with hydrogen in an amount in the range of 1 to 15 mols of hydrogen per mol. of total cyclohexanone and cyclohexanol therein, and contacting the resulting mixture with a dehydrogenation catalyst, such as platinum-on-carbon, at a temperature in the range of 250 DEG to 425 DEG C. at a liquid hourly space velocity in the range of 0.3 to 2.5 per hour. The charge stock is suitably a fraction boiling in the range of 73 DEG C. at 34 mm. Hg. to 205 DEG C. at 6 mm. Hg., the reaction temperature is from 375 DEG to 385 DEG C. and the liquid hourly space velocity 0.7. Phenol having a freezing point of at least 40.0 DEG C. is recovered by fractionating the product under reduced pressure such that the highest temperature is not above 150 DEG C. The charging stock is obtained by air oxidation of cyclohexane in the liquid phase at from 125-180 DEG C., preferably 130 DEG C., in the presence of cobalt naphthenate. The conversion can be 3-16%, preferably 10%. After removal of the unreacted cyclohexane, the desired charge stock is obtained by vacuum distillation. Specifications 929,680 and 939,613 are referred to.
