Py-GC／MS Analysis on Benzene／Ethanol Extractives of Eucalyptus camaldulensis Wood Meal in Pulping Wastewater from South China

摘要

Eucalyptus wood is mainly used for pulping．But water and other chemical aids ale severely wasted because the content of extractives is high．What’s worse,water pollution from the extractives is very serious in South China．Therefore，the benzene／ethanol extractives of E.camaldulensis wood meal were identified by Py-GC／MS．The main constituents were phenol，2-methoxy-4-(1-propenyl)-(6．33%)，phenol,2,6-dimethoxy-4-(2-propenyl)-(6．28%)，phenol,2，6-dimethoxy-(5．7%)，hexadecanoic acid(5．1%)，ethanone，1-(3-methoxyphenyl)-(5．09%)，ergosta-4，6，22-trien-3．beta．-ol(4-38%)，beta-sitostexol(4．05%)，etc．So the benzene／ethanol extractives can be used as biomedicine，bioenergy,and so on.
