摘　　要：以高沸点溶剂环己酮对棉粕脱除棉酚的工艺,运用正交试验优化了萃取条件,确定了环己酮脱除棉酚的最佳工艺条件为:料液比1∶3.5,浸取时间24 h,磷酸浓度1.8 mol/L,环己酮浓度60%。并与以丙酮为溶剂的工艺进行了对比,在浸取时间为25 h时,与丙酮相比,环己酮的棉酚脱除率从59.6%提高到81%,沸点从56.48℃提高到155.65℃,低于国标要求。棉粕脱酚工艺中采用高沸点的环己酮为溶剂,减轻了对环境的污染,提高了棉酚的提取率。In this paper,the optimal conditions of the removal of gossypol by a high boiling point solvent-cyclohexanone is studied.The optimal processing conditions obtained by orthogonal experiment are as follows：the ratio of solid to liquid is 1∶3.5,the concentration of phosphate acid is 1.8 mol/L,and the concentration of cyclohexanone is 60%.Compared with acetone,the removing rate of gossypol of cyclohexanone rises from 59.6% to 81%,and boiling point rises from 56.48°C to 155.65°C,lower than the national requirements.With cyclohexanone as solvent,the new technology decreases the environmental pollution and improves the extraction rate of gossypol.
