METHOD OF PROCESSING FUSEL OIL |
摘要 |
FIELD: chemistry.SUBSTANCE: invention relates to chemical engineering and specifically to processing fusel oil, which is a large-tonnage waste in the alcohol industry. Fusel oil from production of ethyl alcohol is processed by esterification with glacial acetic acid in the presence of a sulphuric acid catalyst, and neutralisation, wherein esterification is carried out while boiling the reaction mixture and continuously separating water using a separating flask. The obtained product is separated from the catalyst under a vacuum at temperature not higher than 110°C. The obtained product and the catalyst are separately neutralised and the obtained product is additionally dried.EFFECT: method enables to process fusel oil into a highly efficient component of mixed solvents of high quality with low cost of production and high output of the product.4 cl |
