PROCESS FOR PURIFYING AQUEOUS ALCOHOLIC SOLUTIONS FOR PREPARING HIGH-GRADE VODKA VARIETIES Russian patent published in 1999 - IPC

FIELD: chemical industry, more particularly purification of aqueous alcoholic solutions with active carbon. SUBSTANCE: active carbon is made of kernels having micropore volume of 0.38-0.50 cu.cm/g, specific surface of 1150-1340 sq.m/g as determined by BET method. Time of contact of aqueous-alcoholic solution with active carbon varies from 1.7-2.6 h. EFFECT: more effective adsorption purification, better quality of vodka and more efficient purification process.
