Embodiment Construction

[0029] The above embodiment 2 can be used as the optimal solution. This solution reduces the initial boiling point of the prepared methanol gasoline, and the vehicle can still be started normally at an ambient temperature of minus 20°C during vehicle use, achieving "triggering at the touch of a button", and solving the problem of difficult cold starting.

[0030] Among the above examples, examples 1 to 4 are formulations for vehicles in winter, examples 5 to 8 are formulations in spring and autumn, and examples 9 to 13 are formulations in summer. Wherein Example 9 is the best solution for use in summer, and this solution mainly overcomes the problem of air resistance when getting off the car at high temperature.

Abstract

The co-solvent composition for compounding methanol gasoline consists of methyl tert-amyl ether 0-61 weight portions, dimethyl carbonate 0-52 weight portions, methyl tert-butyl ether 0-47 weight portions, allcyl polyoxyethylene ether 0.1-10 weight portions, isopropyl ether 0-10 weight portions, ethyl ether 0-30 wt%, tert-butanol 0-45 weight portions, iso-butanol 0-25 weight portions, isopropanol 0-15 weight portions, antioxidant í‹501íŒ 0-8 weight portions, xylene 0-20 weight portions, urotropin 0-7 weight portions, butanone 0-36 weight portions and acetone 0-20 weight portions. It is added while compounding methanol gasoline to raise the intersolubility between methanol and gasoline and raise the relevant physical and chemical performances of methanol gasoline.

Description

technical field [0001] The invention relates to an additive or assistant used in the preparation of methanol and gasoline mixed fuel, especially an additive or assistant capable of homogeneously blending methanol and gasoline. Background technique [0002] Gasoline is a petrochemical product, and today's massive exploitation and utilization of petroleum resources has caused human beings to face a serious situation where natural resources are about to be exhausted. According to evaluation statistics, from now on, the world's average oil exploitation limit is only 30 years, the Middle East has the most abundant oil reserves, only about 90 years, North America is the least, only about 10 years, South America and my country are within the average limit, About 30 years, the average in Asia is about 15 years. Therefore, all countries attach great importance to the research, development and utilization of gasoline substitutes. [0003] On the other hand, since motor vehicles basic...
