摘要
通过利用浓硫酸作催化剂对酸值较高的乌桕油进行预酯化。预酯化后的乌桕油与甲醇在氢氧化钾作为催化剂微波仪中进行酯交换反应得到脂肪酸甲酯,采用单因素实验的方法来研究酯交换反应的最优工艺条件,酯交换反应温度为60℃,反应时间为3 min,催化剂KOH的用量为1.0%(油重),酯交换反应的转化率为98.87%。
The pretreatment of esterificafion to tallow oil which had high acid value was carried out by using sulfuric acid as catalyst. The transesterification of the treated tallow oil and methanol was carried out by using sodium hydroxide to produce fatty methy ester. Through single factor method analysis, the optimum reacting conditions obtained for the transes - terification were set at temperature 60℃, reaction time 3min, and catalyst dosage 1.0% （ on tallow oil mass）. The conversion of transterification was 98.87%.
