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.
Claims32
A method of preparing an olefin comprising:
- (a) providing a composition comprising the polyol, (b) heating the composition in the absence of oxygen, 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;
- wherein the composition is exposed to an inert atmosphere at any time during the heating step.
A method of synthesis of allyl alcohol from glycerol, comprising the steps of:
- providing glycerol and a carboxylic acid to a reaction mixture, heating the reaction mixture under an inert atmosphere in the absence of oxygen, and distilling allyl alcohol from the reaction mixture, whereby allyl alcohol is produced at a yield of about 80% or greater.
A process for synthesis of allyl alcohol from glycerol, comprising the steps of:
- (a) providing glycerol and formic acid to a reaction mixture, (b) heating the reaction mixture under an inert atmosphere in the absence of oxygen to between about 230° C. to about 240° C., and (c) distilling allyl alcohol from the reaction mixture, whereby allyl alcohol is produced at a yield of about 80% or greater.
