摘要
以苯－乙醇为溶剂，在对煤气管道沉积物提取、分离后，采用 ２５ ｍ×０． ２４ ｍｍＩ．Ｄ．的石英毛细管ＯＶ－１０１柱进行了ＧＣ，ＧＣ－ＭＳ分析，鉴定出１９种有机成分，并用归一法作了定量分析，并且采用ＩＲ、点滴试验等方法对其无机物作了定性鉴定。
The deposit in coal gas pipe 1ine was extracted and separated with benzene- ethanol. The extract was analyzed by capillary gas chromatography and gas chromatography- mass spectrometry with 25m×0. 24 mm I. D quartz OV-101 column. Nineteen organic com- ponents were indentified and quantitatively determined. The inorganic compounds of deposit were analyzed by drop test and infrared spetrometry.
