| 摘 要： | 提取松针精油,采用GC-MS技术分析了所得精油的化学成分,并利用提取的精油进行了氨气脱臭实验。松针精油中鉴定出24种主要成分,其中单萜烯、倍半萜烯和含氧萜烯质量分数分别为59.24%、28.39%和6.53%。室温、密闭容器中脱臭时,精油与氨的摩尔比越大,脱臭率越高,以乙醇为溶剂时,脱臭效果更显著。精油原液为脱臭剂的实验中,精油与氨的摩尔比增至12:1时,脱臭率达到100%;精油乙醇溶液(体积比为1:1)为脱臭剂的实验中,精油与氨的摩尔比8∶1时,脱臭率达到100%。

| Abstract: | Essential oil was extracted from pine needles and its compositions were determined by GC-MS.Ammonia deodorization experiment of extracted essential oil was done and 24 organic compounds in the essential oil were identified.Amount of monoterpene,sesquiterpene and oxygenated terpene in the essential oil was 59.24%,28.39% and 6.53% respectively.At room temperature,with mole ratio of essential oils to ammonia was greater in airtight containers,the deodorization rate was higher.While using ethanol as solvent,deo... |
