制备方法与用途

用途

月桂酸油醇酯可作为双酚A环氧树脂的活性稀释剂。它毒性小，使用方便，并能改善一些树脂硬化后的性能，例如抗冲强度等。其参考用量范围为5%～15%。

合成

正丁醇首先与三氟化硼乙醚络合物中的乙醚发生络合反应，生成正负离子对。该正负离子对进一步与环氧氯丙烷进行醚化反应，生成醚化中间体。随后，在碱金属氧化物的作用下，醚化中间体会脱去氯原子并发生闭环反应，最终生成正丁基缩水甘油醚（月桂酸油醇酯）。

  四乙基铵氨基酸离子液体包裹的皱纹念珠菌脂肪酶对脂肪酸酯的酶促酯化反应

  摘要：

  通过使用两种新型的四乙基铵氨基酸离子液体涂层的念珠菌脂肪酶（ILs- CRL）作为己烷中的生物催化剂，研究了油醇与各种脂肪酸的酯化反应生产的脂肪酸酯。通过将皱纹念珠菌脂肪酶与L-组氨酸四乙铵（IL1）和L-天冬酰胺四乙铵（IL2）混合来制备两种酶衍生物。所述ILs- CRL含有等效蛋白质浓度在系统CRL表明特别是中链脂肪酸（C更高酯化活性12 -C 16）相比于未涂覆的CRL。ILs的亲水性可能在与酶表面的氢键结合中起重要作用，从而稳定ILs- CRL。
