摘　　要：采用大豆油在固体碱催化剂作用下与甲醇酯化反应制备生物柴油,研究了醇油摩尔比、催化剂浓度、反应时间、反应温度、搅拌强度对反应产率的影响。试验结果表明:醇油摩尔比6:1、催化剂1.5%、反应时间4h、反应温度65℃、搅拌强度6档为最优操作条件。采用气相色谱分析产品成分,生物柴油质量达到德国指标。Bio-diesel was prepared by transestorification of soybean oil by means of methanol,using solid base catalyst in this paper. The effect of reaction was studied by methanol/oil mole ratio,catalyst dosage,reaction time and temperature, whisk intensity. The results indicated that the optimal conditions for bio-dicsel fuel are methanol/oil mole ratio of 6, catalyst dosage of 1.5%,reaction time for 4h, reaction temperature for 65℃. The chemical compositions were analysised by GC. The quality of bio-diesel reach the target of Germany.
