摘　　要：用傅里叶变换红外光谱仪(FTIR)分析稻壳粉末乙醇解残渣,发现残渣富含含氧基团。依次用CS2和等体积的CS2与丙酮的混合溶剂萃取残渣,得到萃取物E1和E2,用气相色谱/质谱联用仪(GC/MS)分析E1和E2,从E1中检测出3种烷烃、苯族烃和萘族烃各5种、2种含硅有机化合物和2-乙氧基四氢呋喃;从E2中检测出2种含氧有机化合物和5种烃类化合物,其中含氧有机化合物的相对含量比E1中的相应物含量高。The analysis of the residue from the ethanolysis of rice husk powder with Fourier transform infrared spectrometer shows that it is rich in oxygen-containing moieties. The sequential extraction of the residue with CS2 and isometric CS2 and acetone mixed solvent affords extracts 1 and 2 （El and E2）, which are analyzed with gas chromatography/mass spectrometer. Three alkanes, five benzene derivatives, five naphthalene derivatives, two silicon-containing organic compounds and 2-ethoxytetra- hydrofuran are detected in E1 , and two oxygen-containing organic compounds and five hydrocarbons are detected in E2. It is also found that the total content of oxygen-containing organic compounds is much higher in E2 than in E1.
