Methanol gasoline additive and preparation method

Abstract

The invention belongs to the field of an automobile, and particularly relates to a methanol gasoline additive and a preparation method, and the additive can effectively reduce the swelling corrosion on the automobile. The additive comprises isopropyl ether, phenylpropyl triazole, petroleum ether, ferrocene, fatty acid methyl ester, C2C8 alcohol, benzene, Span-80, triethanolamine, 1,3,5,7-tetraazatricycle, isopropanol, alkylphenol polyether and sulfonate; and the additive is composed of the following components in parts by weight: 0.15-0.67 part of the isopropyl ether, 0.03-0.1 part of the phenylpropyl triazole, 0.01-0.08 part of the petroleum ether, 0.02-0.08 part of the ferrocene, 0.03-0.09 part of the fatty acid methyl ester, 0.2-0.8 part of the C2C8 alcohol, 0.4-0.9 part of the benzene, 0.03-0.09 part of the Span-80, 0.03-0.08 part of the triethanolamine, 0.2-0.7 part of the 1,3,5,7-tetraazatricycle, 0.3-0.8 part of the isopropanol, 0.08-0.16 part of the alkylphenol polyether and 0.02-0.08 part of the sulfonate.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a methanol gasoline additive and a preparation method. Background technique [0002] Nowadays, the national government attaches great importance to the sustainable development of the automobile industry, and strongly supports the research, development and market application of new energy vehicles represented by energy vehicles. For this reason, Chinese scientists began to specialize in methanol gasoline in the 1990s, starting from 15% methanol content and gradually increasing it to 85% and 100%. [0003] Additives are needed in the preparation process of methanol gasoline, and the additives are prepared from raw materials with different ratios under certain temperature and pressure conditions. Add the additive to methanol, and then modify the methanol through the organic reaction of methanol and the additive, then add gasoline and anti-oxidation cleaning and stabilizing agent, stir fo...

AI Technical Summary

Problems solved by technology

[0004] However, when the additives produced by the traditional raw material ratio and preparation method are made into methanol gasoline and applied to automobiles, the swelling and corrosion of the automobile oil pump will be caused, and the unburned methanol will flow into the body along the cylinder wall of the combustion chamber. Oil seal swelling and cylinder wall colloid corrosion lead to increased engine wear and reduced engine service life, which is not conducive to long-term maintenance of the car
