This study was conducted to extract scarce natural liquor flavorings desired by many liquor factories from yellow water. Five straight-chain saturated fatty acids were firstly extracted from 15 fractions of yeHow water, forming 1 fraction of the ethanol solution composed of the mixture of the five straight-chain saturated fatty acids. Then, 100 fractions of the ethanol solution could produce 94. 857 6 fractions of esterification liquid through catalytic esterification at 80 m. The esterification...更多
This study was conducted to extract scarce natural liquor flavorings desired by many liquor factories from yellow water. Five straight-chain saturated fatty acids were firstly extracted from 15 fractions of yeHow water, forming 1 fraction of the ethanol solution composed of the mixture of the five straight-chain saturated fatty acids. Then, 100 fractions of the ethanol solution could produce 94. 857 6 fractions of esterification liquid through catalytic esterification at 80 m. The esterification liquid contains five esters: ethyl acetate, ethyl propionate, ethyl butyrate, ethyl valerate and ethyl caproate, with contents of 17. 68V, 2. 58V, 6. 32%, 0.06V and 19.40V, respectively. The esterification liquid prepared from 1 fraction of yeHow water could blend 10. 54 fractions of white liquor into top-grade Luzhou-flavor liquor after esterification. It indicates that yeHow water has very good recycling and utilization value.收起
