Abstract
[Objective]To extract the scarce natural liquor flavoring from yellow water.[Method]First,yellow water was concentrated into dense yellow water by using super absorbent resin to absorb the moisture in the yellow water;next, the previously conentrated yellow water would be azeotropic distillation , and then to adopt catalytic esterification for the remainder liquid after the distillation.[Result]The 7.0667 portion concentrated yellow water with 56.7% alcohol could be obtained after treatment of super strong water-absorbent resin for 100 portion yellow water.Azeotrope of 0.4328 portion natural acetaldehyde, 0.2694 portion ethyl formate and methyl alcohol, 0.9750 portion ethyl ace-tate and methyl alcohol could be obtained after azeotropic distillation of per 100 portion concentrated yellow water.0.2207 portion ethyl for-mate and 0.5142 ethyl acetate could be obtained after distillation with CaCl2 for the azeotrope.92.0948 portion esterified liquid with 38 kinds of flavoring conpounds could be obtained after catalytic esterification of 100 portion concentrated yellow water and the content of ethyl acetate, ethyl propionate, ethylbutyrate, ethyl valerate, ethyl lactate and ethyl hexanoate were as much as 142.9,22.2,54.2,3.3,75.4 and 158.9 g/L.[Conclusion]Superior Luzhou-flavor liquor can be made by mixing 6.5 portion common liquor with acetaldehyde, ethyl formate, ethyl acetate and esterification liquid which are obtained from 1 portion yellow water, so the yellow water has a great recycling value , but also shows the process and method of the research has good value of popularization and utilization value.关键词
