摘　　要：以茶油、甲醇为原料,甲醇钠为催化剂,通过酯交换的方法制备茶油脂肪酸甲酯。结果表明:其最佳工艺条件为油醇比1:12、催化剂甲醇钠0.5%、反应温度80℃、反应时间150 min。在此条件下茶油甲酯转化率为93.17%。所制得茶油脂肪酸甲酯的组分为棕榈酸甲酯9.02%、亚油酸甲酯6.75%、油酸甲酯82.29%、硬脂酸甲酯1.94%。Fatty acid methyl ester were prepared by the transesterification using tea oil and methyl alcohol as raw materials and sodium methoxide as catalyst. The results showed that the optimal process conditions were the molar ratio of tea oil to methanol 1∶ 12,the catalyst sodium methoxide 0. 5%,the reaction temperature 80 ℃,and the reaction time 150 min. Under these conditions,the conversion rate of camellia oil methyl ester was 93. 17 %. The composition of the obtained tea oil fatty acid methyl ester was: methyl palmitate 9. 02 %,methyl linoleate 6. 75 %,methyl oleate 82. 29 %,and methyl stearate 1. 94 %.
