METHOD OF PROCESSING ETHYL ALCOHOL HEAD FRACTION AND CONCENTRATE HEAD FRACTION Russian patent published in 2002 - IPC

FIELD: chemical technology. SUBSTANCE: invention relates to methods of processing ethyl alcohol and concentrate of head fraction using the prepared products as components of alcohol-containing solvents. Method is performed by direct distillation of ethyl alcohol head fraction and concentrate head fraction in the presence of alkaline agents (sodium and potassium hydroxides, carbonates and hydrocarbonates, calcium oxide, ammonia water) taken in the amount 0.01-3.0 wt.-%. Process is carried out at temperature 81-92 C in vat. Vat residue obtained in the process of distillation is used as an addition to fuel mazut. Method provides the use of esters, aldehydes, methanol, ethanol and a possibility to use a vat residue as an addition to fuel mazut. EFFECT: improved method processing. 1 dwg
