荷花是《楚辞》中出现频率最高的“香草”意象之一。
The optimal reaction conditions in yield of 18%~93% at 30 ℃ for 10 h were as follows: vanillyl alcohol was 5 mmol;n(vanillyl alcohol) ∶n(methyl nonanate) was 50 ∶75;lipase was 1 g;ratation speed of shaker was 200 r·min-1.
最佳反应条件为:香草醇5 mmol,n(香草醇)∶n(脂肪酸酯)=50∶75,脂肪酶Novozyme 435(1 g)为催化剂,丙酮(100 mL)为溶剂,摇床转速为200 r。
Vanillyl nonanoate was synthesized using acetone as solvent and NaHCO3 as acid collector by nananoyl chloride and vanillyl alcohol with the yield of 35.
以丙酮为溶剂、NaHCO3为缚酸剂,壬酰氯与香草醇反应合成了壬酸香草醇酯,收率为35。
