Abstract

The invention belongs to the technical field of fuel additives and particularly relates to an alcohol-based fuel preservative. The alcohol-based fuel preservative is prepared from the following raw materials: esters, methyleugenol, 4-nonylphenol, 1-allylbenzotriazole and 2,2'-dipicolylamine, wherein the esters are one or more of eugenyl acetate, ethyl 6-hydroxyhexanoate and dimethyl methylmalonate. The lcohol-based fuel preservative can prevent the metal surface of a fuel system from corrosion and rust, and the service life of equipment is prolonged.

Description

technical field [0001] The invention belongs to the technical field of fuel additives, in particular to an alcohol-based fuel preservative. Background technique [0002] Alcohol-based fuel refers to gasoline containing a certain proportion of methanol or ethanol. Methanol, as a new type of energy to replace traditional fuels, can be blended with gasoline and diesel, and can also be used directly as a fuel. Its advantages in environmental protection, power, and economy are universally recognized. Methanol is considered as "the cleanest automobile engine fuel in the world is methanol fuel", "the future automobile engine fuel is methanol fuel", etc. Authoritative experts predict that it will be the best alternative fuel for fossil fuels in the next 20 to 30 years. [0003] However, the current methanol fuel is easy to absorb water, and there is moisture in the fuel, which will easily cause corrosion and rust on the metal surface of the fuel system, and reduce the service life ...
