Abstract
Provided are processes and products of manufacture that provide a green solution to the hydrolysis of C8/C10 methyl ester to fatty acids. Provided are reactive distillation processes for producing an aliphatic acid and an alcohol as hydrolysis products. Provided are processes and products of manufacture encompassing the hydrolysis of fatty acid alkyl esters to an aliphatic acid and an alcohol by a reactive distillation process. Provided are processes and products of manufacture useful for equilibrium-limited reactions and for the separation of azeotropic mixtures. Provided are reactive distillation products of manufacture and processes for alkyl alkanoate hydrolysis comprising a reaction column comprising a rectifying rectifying zone for further distillation, a reaction zone, and a stripping zone wherein products are separated from reaction mixtures, where a water stream and fatty acid alkyl ester stream can be fed into the reaction section.
