摘要
选择某加油站所售的国ⅥB车用汽油为研究对象,采用顶空气相色谱-质谱法测定国ⅥB车用汽油中挥发性有机组分峰面积比.结果表明:国ⅥB车用汽油中挥发性有机组分主要为C5～C9组分,其中烷烃最多,芳烃其次,烯烃最少;烷烃中异戊烷峰面积比最高,其次是异己烷和三甲基戊烷;芳烃中甲苯峰面积比最高,其次是二甲苯;烯烃主要为C6组分,其中3-甲基-2-戊烯峰面积比最高.国ⅥB车用汽油中挥发性有机组分峰面积比可作为国ⅥB车用汽油危害因素识别与加油站空气中VOCs污染防治的重要依据.
Abstract
The peak area ratio of volatile organic components in China VIB vehicle gasoline sold at a certain gas station was determined using headspace gas chromatography-mass spectrometry.The results show that the volatile organic compounds in China VIB vehicle gasoline are mainly C5-C9 components,in which alkanes are the most abundant,aromatics are the second,and olefins are the least.The peak area ratio of isopentane is the highest in alkanes,fol-lowed by isohexane and trimethylpentane.The peak area ratio of toluene is the highest in aromatic hydro-carbons,followed by xylene.In alkenes,C6 compo-nents are dominant,with 3-methyl-2-pentene having the highest peak area ratio.The peak area ra-tio of volatile organic compounds in China VIB gaso-line can serve as an important basis for identifying hazardous factors of China VIB gasoline and preven-ting VOCs pollution in the air of gas stations.
