TD-GC-MS Analysis on Volatile Organic Compounds of Chinese Fir Biomass in Simulated Hot Drying Environment
As a necessary process, there are many volatile organic compounds of Chinese fir biomass during hot drying to pollute environment and affect the health of the people. Therefore, the chemical components from Chinese fir biomass in simulated hot drying environment were identified by TD-GC/MS to find the possible utilization of the resources and reduce environmental pollution. The main constituents at 90°С were cedrol(25.2%), 1,2-benzenedicarboxylic acid, buty l 2-methylpropyl ester(4.62%), 4-imidazolidinone, 5-(phenylmethyl)-2-thioxo-(3.87%), acetic acid(3.85%), 1-naphthalenepropanol,.alpha.-eth enyldecahydro-.alpha.,5,5,8a-tetra(3.03%), 1,2-benzenedicarboxylic acid, bis(2-methylpropyl) ester(2.07%), hexadecane(2.03%), etc. The main constituents at 120°С were cedrol(30.54%), phenol, 2,4-bis(1,1-dimethylethyl) (3.89%), globulol(2.76%), benzofuran, 2,3-dihydro-(2.71%), cyclohexasiloxane, dodecamethyl-(2.70%),.alpha.-cadinol(2.65%), taurolidine(2.33%), 2,4,6-octatrien-1-ol, 3,7-dimethyl-(E,E)-(2.31%), 3,6,8-nonatrienoic acid, 5-methyl-, ethyl ester(2.26%), 2-furancarboxaldehyde, 5-(hydroxym ethyl)-(2.25%),.tau.-muurolol(2.24%), 7,9-di-tert-butyl-1-oxaspiro(4,5)d eca-6,9-diene-2,8-dione(2.15%), 1-heptadecanamine(2.11%), N-n-butylpropionamide(2.10%), vanillin(2.04%), etc. So the volatile organic compounds of Chinese fir biomass during hot drying could be used as biomedicine, bioenergy, and so on.
