摘要 研究了Mucor sp.JX23发酵液直接生物催化肉桂醛选择加氢制肉桂醇的反应,并考察了肉桂醛质量浓度、反应pH值、温度、时间等因素对反应转化率和选择性的影响。结果表明,Mucor sp.JX23发酵液的最适催化条件为:肉桂醛质量浓度3g/L,反应体系的初始pH=6.0,28℃反应70h。在此条件下,肉桂醛的转化率为82.9%,肉桂醇的选择性为90.4%。 The selective hydrogenation of cinnamaldehyde to cinnamyl alcohol catalyzed by Mucor sp. JX23 fermentation broth was studied. Effects of different factors on cinnamaldehyde conversion and the selectivity to cinnamyl alcohol were investigated. The hydrogenation product was qualitatively analyzed by GC-MS and quantitatively analyzed by HPLC. The best results were obtained with cinnamaldehyde conversion of 82.9% and cinnamyl alcohol selectivity of 90.4% when cinnamaldehyde concentration was 3.0 g/L at pH 6.0, and reaction temperature was 28℃ for 70h reaction time.
