Abstract

The invention discloses an alcohol-based gasoline additive which comprises the following components by weight: 1-3 parts of dimethyl adipate, 0.2-1.5 parts of amyl dicyclohexyl phenol, 0.5-2 parts of oleic acid, 0.005-0.1 part of pentadecafluorooctanoic acid and 0.02-0.15 part of polyisobutene succinimide. The alcohol-based gasoline additive has remarkable effects of preventing rubber swelling and corrosion, can be used for improving the oxidation resistance of alcohol-based gasoline, and has a good industrial application prospect.

Description

technical field [0001] The invention relates to an alcohol-based gasoline multifunctional additive, its preparation method and its specific application in methanol gasoline to solve the problems of rubber swelling, corrosion and oxidation of methanol gasoline, and belongs to the technical field of petrochemical industry. Background technique [0002] As a new type of clean fuel, methanol gasoline has shown certain advantages in terms of economy and vehicle exhaust emissions. It is a new measure to solve energy substitution and control air pollution. [0003] As a clean new energy, methanol gasoline can not only reduce the emission of nitrogen oxides and particulate matter, but also save energy. It has been promoted and tried in some provinces and cities in my country. However, the polar and non-polar components in methanol gasoline will have a serious swelling effect on the rubber parts of the automobile oil system, resulting in aging of rubber parts and oil leakage. At the ...
