固体超强碱催化合成生物柴油

Synthesis of Biodiesel Catalyzed by Solid Super Base

以猪油和甲醇为原料,在固体超强碱催化作用下,发生酯交换反应合成生物柴油;考察了醇油摩尔比,催化剂质量分数,反应时间,反应温度对生物柴油回收率的影响。结果表明,醇油摩尔比为9:1,催化剂质量为动物油质量的2%,70℃反应3h为较理想的反应条件。

Biodiesel was synthesized with the ester exchange reaction from animal oil and methanol catalyzed by solid super base. The influence of the molar ratio of alcohol and oil, quantity of catalyst, reaction time and temperature was investigated. The experimental results show that the optimum condition is the mass fraction of catalyst in animal oil 2 % , the reaction time 3 h, the reaction temperature 70 ℃ and the molar ratio of alcohol to oil 9 ： 1.
