Process for producing peracids from aliphatic hydroxy carboxylic acids

Patent ·
OSTI ID:6714518

A process is disclosed for producing peracids from lactic acid-containing mixtures derived from biomass processing systems. The process includes adjusting the pH of the mixture to about 8 to 9 to form an alkaline precipitate. The alkaline precipitate is then removed therefrom to produce a residual solution containing lower aliphatic hydroxy acids. The residual solution is then oxidized continuously to produce gaseous lower aliphatic aldehydes. The gaseous aldehydes are removed immediately as they are generated to prevent further oxidation to carboxylic acids and are then converted to peracids.
