中文摘要: |
采用非水相酶催化法合成氟比洛芬维生素C酯,使用高效液相色谱和质谱等方法对产物结构进行了表征.同时构建非水相反应体系,通过研究确定最优合成条件:在10 mL、0.057 mol/L的叔丁醇维生素C溶液中,分别添加2.84 mmol氟比洛芬甲酯,10%的N435脂肪酶(以底物的质量分数计),0.8 g分子筛,在70℃,200 r/min的条件下反应28 h.最优条件下的产物转化率为73.63%. |
英文摘要: |
By using five kinds of organic solvents as reaction medium, the immobilized lipase B from Candida Antarctica (Novozym 435) as the biocatalyst, Lipase-catalyzed synthesis of Flurbiprofen VC ester was studied. Thin-layer chromatogram, high-performance liquid chromatogram and mass spectrum has been used to analyze the structure of the product. The non-aqueous reaction system was established and the reaction condition was optimized. In 10 mL, 0.057 mol/L of vitamin C solution of tert-butanol was added 2.84 mmol flurbiprofen ester, the ratio of enzyme to substrate was 5% (W/W), the mount of molecular sieve was 0.8 g, and the temperature was 70℃, the rotating speed was 200 r/min, After the reaction 28 h, the maximum conversion rate of the product reaches 73.63%. |
