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%。
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, deodorization effect was more distinct. When using pure essential oil as deodorant and mole ratio of essential oils to ammonia of 12, deodorization rate can reach 100%. When using ethanol solution of essential oil as deodorant and mole ratio of essential oils to ammonia of 8, the deodorization rate can reach 100%.
