Abstract:
1. A method for preparation of a liquid aliphatic nitrile containing composition comprising the steps of: a) mixing a source of fatty acid sidechains with a nitrogen source to form a mixture; b) heating the mixture at an elevated pressure in a sealable vessel; c) while heating, removing water generated by reaction from the mixture with control of heat, pressure, temperature, and chemical equilibrium through mass transfer to drive a reaction of the source of fatty acid sidechains with the nitrogen source irreversibly to form liquid aliphatic nitriles; and d) distilling a liquid product containing nitrile derivatives of the fatty acid sidechains formed from the reaction mixture and collecting a first distillate of the liquid aliphatic nitrile containing composition for use as a biodiesel fuel.
