ABSTRACT:
Disclosed is a process for converting a carbohydrate or lactic acid feedstock into an ethanol product in the presence of a metal salt at a reaction temperature ranging from about 250.degree. to about 400.degree. C. The improvement comprises establishing a reaction mixture of said feedstock, said metal salt, water, and an organic solvent. The organic solvent has a boiling point above about 150.degree. C., is stable at the reaction temperature, and solvates said feedstock. The solvent is selected from the group consisting of an alcohol, an ether, a tertiary amine, an amine oxide, a quaternary ammonium hydroxide, and a sulfoxide.
