Abstract
Methods of preparing unsaturated compounds or analogs through dehydrogenation of corresponding saturated compounds and/or hydrogenation of aromatic compounds are disclosed.
Claims5
A method of preparing an unsaturated compound, comprising dehydrogenation of a corresponding saturated compound in the presence of a catalyst system under conditions that effect loss of one or more molecules of hydrogen (H2) per molecule of the saturated compound, wherein
- the catalyst system is a heterogeneous catalyst system selected from the group consisting of Pd/C, Pd/alumina, Pd/silica, Pd/CG, Pt/C, Pt/alumina, molybdenum oxide, vanadium pentoxide, Rh/alumina, Ru/Al2O3, bismuth molybdate, and combinations thereof;
- the saturated compound is selected from the group consisting of:
- and
- the unsaturated compound is
- when the saturated compound is
- the unsaturated compound is
- when the saturated compound is
- the unsaturated compound is
- when the saturated compound is
- the unsaturated compound is
- when the saturated compound is
