Problems solved by technology

[0003] Methanol gasoline refers to a new type of environmentally friendly fuel that is blended with national standard gasoline, methanol and additives according to a certain volume (mass) ratio through a strict process. It is a fuel substitute for vehicles and an important part of new energy. Methanol gasoline The mixture is one of the most promising alternative automotive fuels, but in low temperature seasons, the miscibility of methanol-gasoline (indicated by phase separation temperature) often affects the application of such alternative fuels, so it will be added when methanol and gasoline are mixed at low temperature Emulsifier improves its mutual solubility, but most of the existing emulsifiers have poor emulsification effect, large dosage, which affects the combustion effect of methanol gasoline, and the preparation process is complicated and the preparation cost is high

Abstract

The invention relates to a methanol gasoline emulsifier and a preparation method thereof.The methanol gasoline emulsifier comprises solvent oil, ethyl acetate, dimethyl ether and methyl tert-butyl ether.The methanol gasoline emulsifier has the advantages of being easy to prepare and low in preparation cost, can effectively improve intersolubility of gasoline and methanol in a low-temperature environment when used, and is good in emulsification effect, small in dosage and suitable for industrial production. Combustion of the methanol gasoline is not affected, and comprehensive popularization and application of the methanol gasoline are facilitated.

Description

technical field [0001] The invention relates to the technical field of emulsifiers, in particular to a methanol gasoline emulsifier and a preparation method. Background technique [0002] Emulsifier is a kind of substance that can make the mixed liquid of two or more mutually immiscible components form a stable emulsion. The principle of its action is that during the emulsification process, the dispersed phase is dispersed in the continuous phase in the form of droplets (micron scale), and the emulsifier reduces the interfacial tension of each component in the mixed system, and forms a stronger film on the surface of the droplets Or due to the charge given by the emulsifier, an electric double layer is formed on the surface of the droplet to prevent the droplets from aggregating with each other and maintain a uniform emulsion. From a phase point of view, emulsions are still heterogeneous systems. The dispersed phase in the emulsion can be water phase or oil phase, most of ...
