复合裂解高效提取菜油脚—皂脚脂肪酸

Efficient recovery to fatty acids from rape oil foots-soap foots by complex splitting.

为了解决高效提取菜油脚—皂脚脂肪酸的技术关键，显著提高菜油脚—皂脚脂基裂解率和脂肪酸得率，提出水解― 醇解、皂化复合裂解清洁工艺．结果表明，脂基裂解率９８ ％ ，脂肪酸得率９６ ％ ，芥酸纯度９５ ％ ．最佳工艺条件及其影响显著性程度为：水与菜油脚—皂脚体积比３ ：１（ 影响显著） ，水解时间１２ｈ（ 影响显著） ，水解温度１９０ ℃，黑脚醇解－ 皂化时间８ ｈ ．

For solution to technology crux of efficient recovery to fatty acids from rape oil foots-soap foots, notable raise to fat-base splitting rate and fatty acids getting rate on oil foots-soap foots, 'hydrolysis-alcoholysis, saponification' complex splitting cleaner process had been raised. Results had indicated,fat-base splitting rate 98%, fatty acid getting rate 96%, erucic acid purity 95%. The best technology factors and the notable degree of their effects are:volume ratio of water/(rape oil foots-soap foots = 3:1 (effect notable), hydrolysis time = 12h (effect notable), hydrolysis temperature=190℃, alcoholysis-saponification time of black foots = 8h.
