[Objective] This study was conducted to extract the scarce natural liquor flavorings desired by many liquor factories from yellow water. [Method] Strong water absorbent resin was used to absorb moisture from the yellow water in order to concentrate it into dense yellow water at first, followed by azcotropic dis- tillation of the previously concentrated yellow water, and then, catalytic esterification was performed to the remaining liquid after the distillation. [ Results] The 7. 066 7 fractions of concentrated yellow water with 56.7% ethanol could be obtained after the treatment of 100 fractions of yellow water with strong water absorbent resin. Azeotrope of 0.432 8 fraction of natural acetaldehyde, 0. 269 4 fraction of ethyl formate and methyl alcohol, 0. 975 0 fraction of ethyl acetate and methyl alco- hol could be obtained after the azeotropic distillation per 100 fractions of concentrated yellow water. After the addition of CaC12, O. 220 7 fraction of ethyl formate and 0. 514 2 fraction of ethyl acetate could be obtained after distillation of the azeotrope. Finally, 92. 094 8 fractions of esterification liquid with 38 kinds of flavor- ing compound could be obtained after catalytic esterification of 100 fractions of concentrated yellow water, and the content of ethyl acetate, ethyl propionate, ethyl- butyrate, ethyl valerate, ethyl lactate and ethyl bexanoate were as much as 142.9, 22.2, 54.2, 3.3,75.4 and 158.9 g/L, respectively. [ Conclusion] Top-grade Luzhou-flavor liquor could be made by mixing 6.5 fractions of common liquor with acetaldehyde, ethyl formate, ethyl acetate and esterification liquid which were ob- tained from 1 fraction of yellow water. Therefore, the yellow water has a great recycling value, and it tells us that the technique of extracting liquor flavorings from yellow water has tremendous market value. 展开更多
