ABSTRACT:
The invention relates generally to chemical reactions and processes, and in particular to a method for enhancing the rate of a chemical reaction and to apparatus for carrying out the method. The invention more particularly relates to methods and apparatus which utilize microwave and ultrasonic energy to enhance chemical reaction rates; and in specific instances, the invention relates to methods, processes and apparatus for the synthesis of biodiesel fuels. The methods, processes and apparatus of the invention are useful for the synthesis of biodiesel fuels; and also useful for production of reaction products of esterification and/or transesterification reactions including fatty acid alkyl esters.
