月桂酸合成路线

月桂酸上游产品

月桂酸下游产品

月桂酸制备

1.工业生产方法可归纳为两类：一是从天然植物油脂经过皂化或高温高压下分解得到；二是从合成脂肪酸中分离。日本主要以椰子油和棕榈核仁油为原料制取月桂酸。用来制取十二酸的天然植物油有：椰子油、山苍子核仁油、棕榈核仁油及山胡椒仁油等。其他植物中，如棕仁油、擦树籽油、樟树籽油等亦可服务业制取十二酸。提取十二酸所余的C12馏分，含有大量十二烯酸，可在常压加氢，不需催化剂，能以86%以上的转化率转烃为十二酸。

2.从椰子油和其他植物油水解后分离精制而得。

3.以甘油酯形式天然存在于椰子油、山苍子核仁油、棕榈核仁油及胡椒仁油等中。工业上可由天然油脂水解而得。将椰子油、水和催化剂加入高压釜中，在250℃、约5MPa压力下水解成甘油和脂肪酸，其中含十二烷酸达45%～80%，经蒸馏得十二烷酸。

4.棕榈核仁油法　马来西亚的棕榈油产量占全世界总产量的一半以上。其中棕榈核仁油主要由C6～C18的脂肪酸组成，通常月桂酸占46%～51%。

5.山胡椒核仁油法　山胡椒属樟科植物，是一种落叶乔木。山胡椒核果呈球形，果实初为绿色，成熟后为黑色，山胡椒核仁油含月桂酸在30%以上。

其他植物中，如棕仁油、檫树籽油、樟树籽油等亦可用来制取月桂酸。
