Abstract

Purifcn. of aqs. waste contg. nonionic and/or cationic detergents comprises liq.-liq. extraction using 4-20C alcohol(s) or their mixts. with their esters and/or ethers. Pref. solvents are opt. branched 8-10C alcohols, and the adipates, sebacates, phthalates, maleates and fumarates of 4-20C alcohols Extrn. is pref. at 20-100 degrees C, esp. 60-80 degrees C. Used for reducing COD of effluent from detergent prodn minimising foaming, reducing pollution. Process rapidly removes upt to 99.5% of the detergent from the effluent.
