采用气相色谱-质谱联用技术（ GC-MS）对樟脑、松油醇和杉木油这3种不同生产过程中产生的副产品工业双戊烯A、B、C的化学成分进行分析。结果表明：工业双戊烯A、B、C中已鉴定出相对质量分数大于0.1％的成分分别为27、29、33个，其相对质量分数总和分别为98.98％、98.12％、96.34％；3个工业双戊烯样品富含单萜烯类化合物，其组成特征与其来源关系密切，工业双戊烯B含有丰富的桉叶素，而工业双戊烯C中的开环萜烯类和芳香族类物质的含量较高；3个工业双戊烯样品可通过精馏单离出双戊烯、萜品油烯和对伞花烃等产品，还可经适当分离后用作对生产伞花烃原料；此外，工业双戊烯B可提取桉叶油素，工业双戊烯C可提取3，4-二甲基-2，4，6-辛三烯。
採用氣相色譜-質譜聯用技術（ GC-MS）對樟腦、鬆油醇和杉木油這3種不同生產過程中產生的副產品工業雙戊烯A、B、C的化學成分進行分析。結果錶明：工業雙戊烯A、B、C中已鑒定齣相對質量分數大于0.1％的成分分彆為27、29、33箇，其相對質量分數總和分彆為98.98％、98.12％、96.34％；3箇工業雙戊烯樣品富含單萜烯類化閤物，其組成特徵與其來源關繫密切，工業雙戊烯B含有豐富的桉葉素，而工業雙戊烯C中的開環萜烯類和芳香族類物質的含量較高；3箇工業雙戊烯樣品可通過精餾單離齣雙戊烯、萜品油烯和對傘花烴等產品，還可經適噹分離後用作對生產傘花烴原料；此外，工業雙戊烯B可提取桉葉油素，工業雙戊烯C可提取3，4-二甲基-2，4，6-辛三烯。

The Dipentene A,B and C chemical composition of the 3 industrial dipetenne camphor,Alpha-Terpineol and fir oil was an-alyzed by gas chromatography and mass spectrometry (GC-MS).The results showed that,there were 27,29 and 33 compositions which was the relative mass fraction more than 0.1%,and the total relative mass fraction were 98.98%,98.12% and 96.34% in the industrial dipentene A,B and C,respectively.The 3 industrial dipentene enriched with monoterpene compounds,and its chemical compositions had close relationship with its origin source.The industrial dipentene B had a lot of eucalyptol,and the industrial dipen-tene C had higher content of Open-loop terpene compounds and Aromatic substances.The 3 industrial dipentene could be produced into dipentene,terpinolene and p-cymene by distillation,or could be the raw material of synthesis p-cymene.Eucalyptol could be ex-tracted from the industrial dipentene B,and 3,4-dimethyl-2,4-Octatriene could be extracted from the industrial dipentene C.
