中文摘要: |
在无溶剂体系中, 采用介孔分子筛SBA-15固定化P. fluorescens脂肪酶 (PFL)拆分(R,S)-3-氯-1-苯基丙醇. 结果表明, 在以乙酸乙烯酯为酰基供体、 水活度为0.19、 温度为60 ℃、 “记忆”pH为7.0 的优化条件下反应28 h, 酶促拆分转化率(c)达到49.87%, 产物对映体过量值(eep)达到98.73%, 显示了良好的应用前景. |
英文摘要: |
In solvent-free reaction system, the resolution of (R,S)-3-chloro-1-phenylpropanol was performed by P. fluorescens lipase (PFL) immobilized into Mesoporous molecular sieve SBA-15. It was found that conversion (c) of the enzymatic resolution reached 49.87%, and enantiomeric excess for the product (eep) reached 98.73%, under the optimized conditions of using vinyl acetate as acyl donor, water activity 0.19, “memory” pH 7.0, 60 ℃ for 28 h in solvent-free system, presenting a good promise in the enzymatic resolution of (R,S)- 3-chloro-1-phenylpropanol. |
