METHOD OF FUSEL OIL PROCESSING Russian patent published in 2002 - IPC

FIELD: chemical technology. SUBSTANCE: method is performed by rectification with addition 0.01-3.0 wt.-% of alkaline agent (sodium and potassium hydroxides, carbonates and hydrocarbonates, calcium oxide, ammonia water) to temperature 131-132 C in the column vat and to 128-129 C in the condenser gaseous zone. Content of impurities in condensate is up to 3 wt.-%. Prepared vat product is subjected for direct distillation. For preparing technical isoamyl alcohol the rectification process is carried out with addition of an alkaline agent also to temperature 121-127 C in vat, water content in mass is 0.35-0.8 wt.-%. Obtained isoamyl alcohol satisfies to technical requirements. EFFECT: improved method of processing. 3 cl, 2 dwg
