据报道,2005年4月1日,安徽、江苏、江西和山东四省即将同步推广乙醇汽油,同时各加油站也相继禁止销售普通汽油。四省为何做出这样的决定,用化学方法如何制作酒精,操作过程需要注意的具体事项有哪些?现结合本人体会,谈谈管窥之见。一、推广使用乙醇汽油的意义车用乙醇汽油是指在汽油组分中按体积混合加入10％的变性乙醇燃料(C_2H_5OH)后作为汽车燃料用的汽油。研究结果表明,燃料乙醇作为汽油燃料具 According to reports, on April 1, 2005, the four provinces of Anhui, Jiangsu, Jiangxi, and Shandong will soon promote the use of ethanol gasoline. At the same time, gas stations have also banned the sale of regular gasoline. Why did the four provinces make such a decision and how to make alcohol using chemical methods? What are the specific issues that need to be noted during the operation? 1. Significance of Promoting the Use of Ethanol Gasoline Ethanol gasoline is gasoline that is used as fuel for automobiles when 10% of denatured ethanol fuel (C_2H_5OH) is mixed by volume in the gasoline component. Research results show that fuel ethanol is used as a gasoline fuel
