摘要

: Rhodinol是香茅醛和香叶醇的混合物,可以用有机酸酯化成香茅醛酯和香叶醇酯,产生特定的气味作为香料。本研究以香茅油为原料,将香茅油中的香茅醛先还原为香茅醇,合成了Rhodinol酯。用nabh4在以乙醇为溶剂和无溶剂及摩尔比变化的条件下进行了还原。通过还原产物(rhodinol)的酯化反应制备rhodinol酯。在没有溶剂的情况下,以香茅醛与nabh4的摩尔比为1:1的条件下,香茅油中香茅醛的还原效果良好,成功地将香茅醛转化为香茅醇,其中香茅醇和香叶醇的总含量为65.85%。红景天醇酯化反应产69.69%的红景天醇酯,其中含有55.16%的香茅酰乙酸酯和14.53%的香叶酰乙酸酯。

Synthesis of Rhodinol Ester from Citronella Oil Reduction Product
: Rhodinol is a mixture of citronellol and geraniol that can be esterified using organic acids into citronellol esters and geraniol esters to generate a specific odour as fragrances. Rhodinol esters in this study were synthesized from citronella oil by first reducing to convert the citronellal in citronella oil into citronellol. Reduction was carried out using NaBH 4 in conditions with ethanol as a solvent and without a solvent and the variation of mole ratio. Esterification of reduction product (rhodinol) was done to produce rhodinol ester. Reduction citronellal in citronella oil was efficient without solvent in the mole ratio of citronellal and NaBH 4 1:1, and successfully converted citronellal to citronellol with the rhodinol total (citronellol and geraniol) was 65.85%. Esterification of rhodinol produced 69.69% rhodinol ester which contains 55.16 % citronellyl acetate and 14.53% geranyl acetate.
