摘　　要：通过GC和GC MS,研究了香叶基丙酮合成反应过程中馏出物的主要化学组成及其特征。结果表明,反应馏出物中除含正常的乙醇以外,还有未来得及反应而被夹带出来的原料乙酰乙酸乙酯和芳樟醇,其次还含有少量分解产物乙酸乙酯和乙酸、脱水产物月桂烯、异构产物香叶醇和橙花醇等成分,同时含有较多的来源于原料的杂质成分。实验室和工业规模条件下,对于本合成反应的控制存在明显的不同,小试验较易于控制两种反应原料的馏出,而在中试生产时则更易于控制产物香叶基丙酮被夹带。The reaction distillate from synthesis of geranylacetone was analyzed through GC and GCMS to investigate its composition as well as reformation mechanism.As results,besides main ethyl alcohol as predicted in the distillate,there are entrapped raw reactants ethyl acetoacetate and linalool,and small amounts of goal geranylacetone,ethyl acetate and acetic acid from decomposing of ethyl acetoacetate,myrcene from dehydration of linalool,geraniol and nerol from isomerization of linalool,as well as the impurities existed in the raw materials.The results also showed that the reactants are easy to be controlled in the laboratory,but on the contrast the entrapped geranylacetone is easy to be cut off in a pilot.
