摘要
汽油中甲醇含量太高会影响油品质量且对汽车的供油系统及进气系统构成腐蚀,因此,国家对汽油中的甲醇含量作了一定的限制。本实验测定了NB/SH/T 0663-2014《汽油中醇类和醚类含量的测定气相色谱法》甲醇含量的检出限,甲醇的检出限为0.033%,远远小于0.20%。所以,在该标准下完全可以用Agilent Technologies 7890B GC System去测定甲醇含量。
High methanol content in gasoline will affect the quality of oil products and erode the automobile oil supply system and intake system.Therefore,China sets a limit on the methanol content in gasoline.This paper determined the detection limit of methanol specified in the NB/SH/T 0663-2014,Determination of alcohols and ethers in gasoline Gas chromatograhy,namely 0.033%,which is far less than 0.20%.Therefore,Agilent Technologies 7890 B GC System can be used to determine the methanol content,following this standard.
