  • Method of converting a polyol to an olefin
    Patent number: 8273926
    Abstract: A method of preparing an olefin comprising: reacting a polyol in the presence of a carboxylic acid, such that an olefin is produced by the deoxygenation of the polyol. The reacting step can comprise (a) providing a composition comprising the polyol, (b) heating the composition, and (c) introducing the carboxylic acid to the composition wherein the introducing step occurs prior to, at the same time as, or subsequent to the heating step. In one embodiment, the polyol is glycerol, the carboxylic acid is formic acid, and the olefin is allyl alcohol, which is produced at a yield of about 80% or greater.
