How it is made

Catalytic oxidation of cyclohexane

Obtained from cyclohexanol by catalytic dehydrogenation or by oxidn (which yields cyclohexanone & adipic acid) ... British patent 310,055 (schering-kahlbaum 1928), us patents 2,223,493-4 (du pont 1940), 2,285,914 (du pont 1942).

Catalytic hydrogention of phenol or by the catalytic air-oxidation of cyclohexane, may be prepared by either the catayltic dehydrogenation or oxidative dehydrogenation of cychexanol. The process is carried out in either a liquid phase catalyzed by palladium or carbon, or in the vapor phase catalyzed by palladium or alumina.
