The emission of phenols from a European car working with leaded and unleaded fuels with different percentage of aromatics has been considered. Fuels having the same aromatic content, but with a different composition of aromatic fraction, have also been taken into account. The results obtained showed that the emission of phenols increases with the increase of the aromatic content of fuel and also when unleaded instead of leaded fuels are used. The type of aromatic present in fuels was found to be important in forming the amount of both total and individual phenols emitted in the exhaust gas and in determining the number of phenolic compounds formed during combustion, although the phenol and isomer cresols were produced by combustion of all the fuels tested. The quantitative determination of individual phenols has been carried out on the benzene extract of the aqueous condensate and of the particulate matter of exhaust gas by the NaOH-extraction-GC-chromatographic method.
研究了一辆欧洲汽车使用含不同芳烃百分比的含铅和无铅燃料时酚类的排放情况。还考虑了具有相同芳烃含量但芳烃馏分组成不同的燃料。所得结果表明，酚类排放随着燃料芳烃含量的增加而增加，并且在使用无铅燃料而非含铅燃料时也会增加。尽管所测试的所有燃料燃烧都会产生苯酚和异构甲酚，但发现燃料中存在的芳烃类型对于形成废气中排放的总酚和单个酚的量以及确定燃烧过程中形成的酚类化合物数量很重要。已通过NaOH萃取 - 气相色谱法对废气的水冷凝物和颗粒物的苯提取物中的单个酚进行了定量测定。
