Abstract

An antiknock chemical additive for lead-free gasoline comprises the raw materials in parts by weight: 30-40 parts of industrial ethanol, 10-20 parts of industrial methanol, 5-10 parts of ferrocene, 2-10 parts of monomethyl aniline, 5-10 parts of isobutyl acetate, 20-30 parts of methyl tertiary butyl ether, and 10-15 parts of xylene. The addition amount of the antiknock chemical additive in the lead-free gasoline is 0.2-1.0%. The gasoline octane number can be increased by 20-40 units, and the antiknock property and the dynamic property of the gasoline are enhanced. The antiknock chemical additive has the advantages of easily obtained raw materials, low cost, simple process, and easy popularization; the antiknock chemical additive has obvious using effect, significantly increases the octane number, improves oil product chemical properties, has a catalytic combustion function, can allow mixed gas to be fully burnt, improves the oxidation speed, thereby reducing knocking occurrence and having good speed increasing performance; and emissions of CO, hydrocarbons, NOx and solid particles in exhaust gas are greatly reduced, environmental pollution is reduced, moreover, the lead content is extremely low, and economic benefits and social benefits are substantial.

Description

technical field [0001] The invention relates to a chemical additive, in particular to an antiknock chemical additive for unleaded gasoline. Background technique [0002] Due to the quality problems of the fuel itself and the insufficiency of the mechanical manufacturing limit of motor vehicles, there will be chilling effects, gap effects, prone to knocking, intake valves, and carbon deposits in electric nozzles; waste of fuel, pollution of the atmosphere, etc. Contents of the invention [0003] In order to overcome the above-mentioned shortcoming of the prior art, the object of the present invention is to provide a kind of unleaded gasoline anti-knock chemical additive, significantly improve octane number, improve oil chemical performance, have the effect of catalytic combustion, can make mixed gas fully burn, Increase the speed of fireworks, thereby reducing the occurrence of knocking, less environmental pollution, and significant economic and social benefits. [0004] I...
