以丙酮为助溶剂，氢氧化钾为催化剂，研究了植物油与甲醇的酯交换反应。考察了丙酮用量、KOH用量、醇油摩尔比、反应温度等因素对脂肪酸甲酯（FAME）产率的影响。最佳工艺条件为：25 wt.%丙酮和1.0重量%油中的KOH催化剂;甲醇与油的摩尔比为4.5：1;反应温度为25 ℃。在此条件下，30 min后植物油转化为FAME的转化率超过98%。将该方法应用于从废弃食用油（WCO）、菜籽油、鲶鱼和小桐子油生产生物柴油（BDF），产品主要质量指标满足JIS 2390 BDF标准。(C)2012爱思唯尔有限公司保留所有权利。
An homogeneous reaction process using acetone as a co-solvent for the transesterification of vegetable oils with methanol in the presence of potassium hydroxide catalyst has been developed. The effects of the main parameters, such as the amounts of acetone and KOH, the molar ratio of methanol to oil and the reaction temperature, on fatty acid methyl esters (FAME) yield were investigated. The optimal conditions were: 25 wt.% acetone and 1.0 wt.% KOH catalyst in oil; a molar ratio of methanol to oil of 4.5: 1; and a reaction temperature of 25 degrees C. Under these conditions, the conversion of vegetable oil to FAME exceeded 98% after 30 min. This method was applied to produce biodiesel fuel (BDF) from waste cooking oil (WCO), canola, catfish and Jatropha curcas oils, with the main product quality factors satisfying the JIS 2390 BDF standards.
