Chemical Components Determination of Benzene/Ethanol Extractives of Eucalyptus camaldulensis Wood by Py-GC/MS
Eucalyptus wood begins to be used for pulping.However,water and other chemical aids are severely wasted because the content of extractives is high.What is the worst,water pollution from the extractives is very serious.Therefore,the chemical components from fresh E.camaldulensis wood were extracted with benzene/ethanol and identified by Py-GC/MS after concentration.Relative content of each component was determined by area normalization.56 compounds of the extractives were identified.The main constituents were stigmasterol,22,23-dihydro-(19.11%),stigmastan-3,5-diene(4.98%),stigmastanol(4.77%),ethanediai(4.13%),stigmast-4-en-3-one(4.06%),acetone(3.3%),n-hexadecanoic acid(3.11%),1-hexacosanol(2.71%),9,19-cyclolanost-25-en-3-ol,24-methyl-(2.45%),9,12-octadecadienoic acid(z,z)-(2.17%),9,19-cycloergost-24(28)-en-3-ol,4,14-dimethyl-(2.16%),vitamin E(2.12%),cyclopropa5,6stigmast-22-en-3-one,3,6-dihydro-(1.77%),acetic acid(1.34%),ethanol(1.19%),cedrol(1.12%),benzene(1.09%),(1.04%),etc.The main components of benzene/ethanol extractives of fresh E.camaldulensis wood are not only abundant and healthy to human,but can also be used as bioenergy materials.
