摘要： 羟基香茅醛具有玲兰样香气,是一种传统的合成香料,主要用于调配各种花系列香精、食品香精、化妆品香精等。我们对它的合成方法进行了改进研究,用二乙醇胺与香茅醛缩合生成噁唑烷衍生物,将醛基保护,再用硫酸加助催化剂将其双键水合,进而将缩合物水解得握基香茅醛。

Abstract: The hydroxycitronellal has been synthesized from citronellal. The oxazolidine derivative has been prepared from citroncllal and diethanolamine by using dehydrator for protecting citroncllal carbonyl. The citroncllal-dicthanolamine adduct were hydrated with the sulfuric acid and an affix catalytic promoter with subsequent hydrolysis to hydroxycitronellal.The optimum experimental conditions were obtained by using orthogonal experimental design. Thc yield of the condensation compound and the hydroxycitronellal have been achieved to be 96.6% and 87.7% respectively. The rate of inversion of the citronellal achieved 84.7%.

Key words: hydroxycitronellal, citronellal, diethanolamine, perfume
