Five straight-chain saturated fatty acids were firstly extracted from 15 fractions of yellow 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 ℃. The esterification liquid contains five esters： ethyl acetate, ethyl propionate, ethyl butyrate, ethyl valerate and ethyl caproate, with contents of 17.68%, 2.58%, 6.32%, 0.06% and 19.40%, respectively. The esterification liquid prepared from 1 fraction of yellow water could blend 10.54 fractions of white liquor into top-grade Luzhou-flavor liquor after esterification. It indicates that yellow water has very good recycling and utilization value.展开更多
