Methanol gasoline additive for vehicles and preparation method thereof

The invention relates to a methanol gasoline additive for vehicles and a preparation method thereof, belonging to the technical field of petrochemical industry and aiming to solve the problems of mutual dissolution, corrosion, air resistance, swelling and the like in the preparation process of methanol gasoline. In a technical scheme, the methanol gasoline additive for vehicles is prepared by mixing the following raw materials in parts by weight: 15 to 30 parts of ethanol, 10 to 20 parts of isopropyl ether, 1 to 9 parts of dimethyl carbonate, 1 to 15 parts of acetone, 0.1 to 6 parts of dimethyl ketone, 0.5 to 8 parts of isopropanol, 1.5 to 10 parts of tertiary butanol and 1 to 8 parts of iron naphthenate. The preparation method comprises the steps of weighing raw material components according to the weight parts, and mixing and standing under normal temperature and pressure. The methanol gasoline additive for vehicles has the advantages of good safety and environment protection, and well solves the problems of mutual dissolution, corrosion, air resistance, swelling and the like in the preparation process of the methanol gasoline, and the preparation method has the advantages of preparation under normal temperature and pressure, simple technology, and simple and convenient operation. The methanol gasoline blended with the additive is suitable for various vehicles and has excellent economy and market application prospects.
