试验研究了猪油在催化剂(NaOH)的作用下与甲醇发生转酯化反应生成脂肪酸甲酯(生物柴油)的工艺条件。试验结果表明,该转酯化反应的最佳操作条件为:NaOH用量为猪油量的1.0%、醇油摩尔比6:1、反应温度60℃、反应时间(60～75)min。
The process conditions of lard oil transesterification with methanol under the action of catalyst (NaOH) to produce fatty acid methyl ester (biodiesel) were studied. The results showed that the optimum conditions for the transesterification reaction were as follows: the dosage of NaOH was 1.0% of lard, the molar ratio of alcohol to oil was 6: 1, the reaction temperature was 60 ℃ and the reaction time was 60-75 min.
