摘要: In order to significantly improve the biosynthesis of acyl-L-carnitines catalyzed by lipase, there must be an efficient and suitable reaction medium that is not only polar but also hydrophobic. [Bmim]PF6, which satisfies the above two requirements, was applied as the medium. The optimal reaction conditions were: for isovaleryl-L-carnitine, 0.22a4(W), 200mg molecular sieves, 60oC, 4: 1 of molar ratio (fatty acid: L-carnitine), 150rpm and 60h; for octanoyl-L-carnitine and palmitoyl-L-carnitine, 0.22a(W), 250 mg molecular sieves, 5: 1 of molar ratio (fatty acid: L-carnitine), 200rpm, 48h, 60((sic))C (octanoyl-L-carnitine) and 65((sic))C (palmitoyl-L-carnitine). Their overall yields could reach 59.14%, 90.79% and 98.03%, respectively. The yields of isovaleryl-L-carnitine, octanoyl-L-carnitine and palmitoyl-L-carnitine in [Bmim]F-6 were 16.21%, 73.67% and 44.22% more than those in acetonitrile, respectively. [Bmim]PF6 as the medium was better than acetonitrile. It could not only enhance the yields of acyl-L-carnitines, but also protect the lipase activity.
