Abstract

Phenol is produced from an oxygenated cyclohexane fraction which contains cyclohexanone and/or cyclohexanol and also contains a (non-phenolic) impurity which boils at about the same temperature as phenol, by vaporizing said fraction and 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 degrees to 425 degrees at a liquid hourly space velocity in the range of 0.3 to 2.5 per hour, and recovering phenol product as a distillate free from impurity. The charge stock is suitably a fraction boiling in the range of 54 DEG to 94 DEG C. at 23 mm. Hg, and the reaction temperature preferably 375-385 DEG C., and liquid hourly space velocity 0.7 per hour. Phenol having a freezing point of at least 40.0 DEG C. may be recovered by fractionating the reaction product under reduced pressure conditions such that the highest temperature is not over 150 DEG C. The initial fraction may be obtained by air oxidation of cyclohexane at 125-180 DEG C., preferably 130 DEG C. in the presence of cobalt naphthenate until 10% of the cyclohexane is oxidized. After removal of unreacted cyclohexane the mixture is vacuum distilled to obtain the desired cut. Specifications 929,680, 939,613 and 986,932 are referred to.
