Abstract
The catalytic dehydrogenation of at least one dehydrogenatable organic compound which has at least one ##STR1## grouping is carried out in the presence of a zinc titanate catalyst. The selectivity of the zinc titanate catalyst is improved by at least one promoter selected from the group consisting of chromium oxide, antimony oxide, bismuth oxide, oxides of the lanthanides, oxides of the actinides, oxides thereof, and compounds convertible to the oxides thereof.
Claims14
A process for the catalytic dehydrogenation of at least one dehydrogenatable organic compound which has at least one ##STR3## grouping comprising the step of contacting said at least one dehydrogenatable organic compound, under suitable dehydrogenation conditions in the substantial absence of free oxygen with a catalyst composition comprising zinc, titanium, and at least one promoter selected from the group consisting of chromium, antimony, bismuth, the lanthanides, the actinides, oxides thereof, and compounds convertible to the oxides thereof, wherein the concentration by weight of said at least one promoter in said catalyst composition is less than the total concentration by weight of said zinc and said titanium in said catalyst composition wherein said zinc and said titanium are present in said catalyst composition in the form of zinc titanate which is prepared by calcining a mixture of zinc oxide and titanium dioxide in the presence of free oxygen at a temperature in the range of about 650.degree. C. to about 1050.degree. C.
