'邬国英等对氢氧化钾催化棉籽油和甲醇制取生物柴油的酯交换反应进行了研究。棉籽油酯交换反应在醇油摩尔比6∶1，KOH质量分数1.1%，45℃下反应1h，酯交换转化率可达98.33%，制得的棉籽油甲酯生物柴油主要性能指标符合ASTM制定的生物柴油标准。游离脂肪酸会与碱发生皂化反应，过量的水则使皂化反应更易进行。某些情况下形成的脂肪酸钠、甲醇和油形成稳定的乳化液，将导致脂肪酸甲酯与甘油的分相困难。而且用均相碱催化剂生产会产生大量碱性废液，对环境造成较严重的污染，因此有必要开发固体碱催化剂取代均相碱催化转酯化反应。'

Wu Guoying and others studied the transesterification of cottonseed oil and methanol to Biodiesel Catalyzed by potassium hydroxide. The transesterification conversion of cottonseed oil methyl ester biodiesel can reach 98.33% when the alcohol oil molar ratio is 6 ∶ 1, the mass fraction of KOH is 1.1% and 45 ℃ for 1H. The main performance indexes of cottonseed oil methyl ester biodiesel meet the biodiesel standard formulated by ASTM. Free fatty acids will saponify with alkali, and excessive water will make the saponification easier. In some cases, fatty acid sodium, methanol and oil form a stable emulsion, which will make it difficult to separate fatty acid methyl ester from glycerol. Moreover, the production of homogeneous alkali catalyst will produce a large amount of alkaline waste liquid and cause serious pollution to the environment. Therefore, it is necessary to develop solid alkali catalyst to replace homogeneous alkali catalyzed transesterification.。
