cleaved in the presence of an acid catalyst like zeolite. Phenol [108-95-2] and acetone [67-64-1] produced in the process are recovered by distillation. Ratio of phenol to acetone is 1:0.6. (2) By Dehydrogenation of 2-proponal The hydration of propene [115-07-1] gives 2-propanol [67-63-0]‚ which is then dehydrogenated to acetone. In the United States a C3 stream containing 40 – 60 % propene is used for the manufacture of 2-propanol. A large number of catalysts for 2-propanol dehydrogenation have
