摘要: 提供一种新的快速检测方法,并且配合方法研制出了相应的便携仪器。该方法通过测定萃取液,排
除了汽油中烃类和醚类的干扰;通过特殊的复合催化剂A的应用,使得醇类的转化仅到相应醛的程度。以某种特定
的酸B为显色剂,排除其他可能存在的醇类的干扰。应用该方法和仪器对10个汽油样品检测(5个车用乙醇汽油,5
个车用无铅汽油),以气相色谱法测定值作为真值,考察了该方法的快速性、选择性、可靠性,并比照其他快速法,从
测试数据的重复性和准确性方面验证了该方法的优越性。

Abstract: This research affords a new method to test the content of methanol in the gasoline, and a special portable instrument was developed according to this method. The disturbance caused by the existence of hydrocarbons and ethers in gasoline was excluded by extraction, and the alcohol was selective oxidized to aldehyde over catalyst A, and the presence of other alcohol can be neglected by selecting suitable color developing agent. The methanol content in 10 different kinds of gasoline samples (including samples of five Ethanol gasolines and of five unleaded gasoline) has been tested by this special instrument. According to the experimental data with GC and this method, the testing speed, selectivity and reliability of the method has been investigated, and the results shows that good reproducibility and accuracy of this method has been demonstrated as compared with those of other rapid test methods.
