Abstract
A process for the continuous production of monocarboxylic acids from the corresponding alcohols by alkali fusion wherein the oxidation is continuously accomplished in an extrusion reactor without addition of diluents and the alkali salts of the monocarboxylic acids are discharged from the reactor as a solid product and are directly neutralised with mineral acids. High-purity monocarboxylic acids are obtained after phase separation.
