Abstract
The invention relates to the field of gasoline additives, in particular to a high-cleaning-efficiency gasoline additive. The high-cleaning-efficiency gasoline additive mainly comprises the following components in percentage by volume: 8-10 percent of a dispersing agent, 0.5-1 percent of a polymerization inhibitor, 1-3 percent of a light stabilizer, 0.5-1 percent of an emulsion breaker, 1.5-10 percent of a rust inhibitor, 6-10 percent of a cosolvent and the balance of basic liquid. The adding amount of the high-cleaning-efficiency gasoline additive in gasoline is 0.05-0.2 percent by volume. The high-cleaning-efficiency gasoline additive is suitable for leaded gasoline and unleaded gasoline. By using the high-cleaning-efficiency gasoline additive, the generation of oil sludge and carbon deposits can be reduced greatly, generated deposits can be cleaned, fuel is saved, and the power performance of an automobile engine is improved effectively, and the content of harmful substances produced by incomplete combustion in emitted tail gas is lowered.
Description
Technical field
The invention belongs to gasoline dope field, be specifically related to a kind of high-clean gasoline additive.
Background technology
21st century is environmental protection century, and the discharge that reduces obnoxious flavour in vehicle exhaust is a problem anxious to be resolved.Important pollutent in exhaust emissions is hydrocarbon polymer, carbon monoxide and nitrogen oxide.Hydrocarbon polymer easily generates ozone in the sun and forms chemical smoke with nitrogen oxide after entering atmosphere, and the ozone in high-altitude can cover ultraviolet ray, favourable to human body, and the ozone in low latitude can insulting respiratory system, also can affect crop growth.Carbon monoxide enters blood of human body and is combined with oxyphorase, can reduce blood transport function, causes poisoning even causing death when serious.Nitrogen oxide not only affects human respiratory, causes the generation of trachitis, pneumonia and pulmonary disorder, is also the main component of producing acid rain.
China's gasoline composition has been compared very big-difference with external gasoline, most importantly catalytic cracking component proportion is high, the chief component of catalytic cracking is alkene, at high temperature very easily oxidation, polymerization generate weakly acidic greasy filth and carbon distribution to the high gasoline of olefin(e) centent, this will cause engine oil path to stop up, air-fuel ratio imbalance, incomplete combustion, engine power declines, and causes obnoxious flavour amount in emission to increase.
In gasoline, adding high-clean gasoline additive is one of effective way addressing this problem.High-clean gasoline additive is a kind of tensio-active agent, it not only has effect of cleaner engines oil piping system, and the particle washing down can be disperseed, take away burning by gasoline, thereby recover the normal fuel injection function of engine, improve engine combustion state, reduce the exhaust emission being increased by incomplete combustion.
Summary of the invention
Main purpose of the present invention is to provide a kind of high-clean gasoline additive, this additive add-on is little, can significantly reduce the generation of greasy filth, carbon distribution, the also settling having generated capable of washing, fuel economy, effectively improve motor car engine dynamic performance, reduce the harmful substance contents producing due to incomplete combustion in exhaust emissions.
High-clean gasoline additive of the present invention, be made up of dispersion agent, stopper, photostabilizer, emulsion splitter, rust-preventive agent, solubility promoter and basal liquid, its volume addition is respectively: dispersion agent 8～10, stopper 0.5～1, photostabilizer 1～3, emulsion splitter 0.5～1, rust-preventive agent 1.5～10, solubility promoter 6～10, basal liquid surplus.
Described dispersion agent is benzoyl polyisobutene Dimethylamino pyridine.Its effect is by the basic group of macromole one end and the oil-soluble group of the other end, carbon distribution to be dissolved in gasoline, reaches the object of peptization, solubilising and cleaning.
Described photostabilizer is the two water oxygen acid esters of dihydroxyphenyl propane.Its effect is to absorb high-energy free radical, thereby prevents the generation of coking and minimizing and inhibited oxidation nitrogen under high temperature.
Described rust-preventive agent is benzal ketoamine derivative.
Described basal liquid is the mixed solution of kerosene and BTX aromatics, and ratio is 1:1.These two kinds of composite basal liquids and other solvent phase ratios, have better solubility property to greasy filth and coking, and add in gasoline with the additive of high density, can not produce and dissolve and expand the sebific duct in pneumatic thickener assembly, plastic component, purifier and oil pump.And after gasoline combustion, can not produce secondary pollution.
Stopper, emulsion splitter and solubility promoter are existing common solvent.
The addition of described high-clean gasoline additive in gasoline is volume fraction 0.05% ~ 0.2%.
Described high-clean gasoline additive is applicable to doped fuel and white gasoline.
High-clean gasoline additive of the present invention, add in gasoline, as motor spirit, can significantly reduce the generation of greasy filth, carbon distribution, the also settling having generated capable of washing, reach fuel economy, effectively improve motor car engine dynamic performance, reduce the harmful substance contents producing due to incomplete combustion in exhaust emissions.
Embodiment
(1) benzoyl polyisobutene Dimethylamino pyridine preparation
Chlorinated benzene formyl and high-activity polyisobutene are added in reactor, at 125 DEG C, react 4h, obtain benzoyl polyisobutene, worth benzoyl polyisobutene and the chloro-DMAP of 3-are led to hydrogen at appropriate Raney nickel catalyzator effect lower seal, in (200～220) DEG C, under 8～10MPa condition, react 4h, through cooling, filtration distillation, dehydration obtains benzoyl polyisobutene Dimethylamino pyridine.
(2) configuration of high-clean gasoline additive
