Claim Text:
1. A process for preparing an olefin comprising: subjecting a material to a reductive dehydroxylation in presence of an iodine-based catalyst, a liquid reaction medium, and 0.1 wt % to 100 wt % gaseous hydrogen to form an olefin; performing the reductive dehydroxylation under conditions comprising a hydrogen pressure ranging from 1 psig to 2000 psig, a temperature ranging from 50° C. to 250° C., and a ratio of moles of the material to moles of iodine atoms in the iodine-based catalyst ranging from 4:1 to 27:1; wherein the material is selected from the group consisting of a vicinal polyol, an ester of a vicinal polyol, and combinations thereof; and wherein the iodine-based catalyst is selected from the group consisting of iodine (I
