摘要: 以杉木屑为原料,采用干馏法制备杉木油,分别得到干馏油、木醋液、焦油和木炭,产率分别为4.0%、38.0%、14.3%、28.8%,除此之外还得到不凝性可燃气,产率为15.0%。对杉木屑干馏油、木醋液和不凝性气体的性质、组成进行研究,结果发现:杉木屑的固液产品总转化率达到了80%以上;杉木干馏油的主要组成为α-柏木烯29.36%、β-柏木烯11.87%、柏木醇12.10%等;木醋液的主要成分为1-甲基亚乙基环己烷24.07%、乙酸19.77%、4-乙基愈创木酚11.71%、糠醛8.06%等;不凝性可燃气主要由H2、CO和CH4组成。

Abstract: Essential fir oil was prepared by destructive distillation using Chinese fir chips as raw material. The yields of destructive distillation oil, wood vinegar, tar and charcoal were 4.0%, 38.0%, 14.3% and 28.8%, respectively. Non-condensable flammable gas was also generated during destructive distillation, the yield of gas was 15.0%. The property and composition of destructive distillation oil, wood vinegar and non-condensable gas were studied. The results showed that all of the fir chips were converted into products with conversion rate over 80%. The compositions of destructive distillation oil were α-cedrene 29.36%, β-cedrene 11.87%, cedrol 12.10%, etc. The main organic components of the vinegar were 1-methyl-ethylidene-cyclohexane 24.07%, acetic acid 19.77%, 4-ethylguaiacol 11.71%, furfural 8.06%, etc. Main components of non-condensable combustible gas were H2, CO and CH4.
