Abstract
The invention discloses a transition metal gasoline antiknock agent which comprises a manganese metal organic substance and an arylamine compound, wherein in terms of 10000 parts of the antiknock agent by weight, the manganese metal organic substance accounts for 4-16 parts and the arylamine compound accounts for 99996-99984 parts. The transition metal gasoline antiknock agent disclosed by the invention has the advantages that gasoline, added with the transition metal gasoline antiknock agent, is relatively low in influence on spark plugs and engines because deposited manganese metal generated from combustion of fuel is much less than an antiknock agent containing the manganese metal organic substance as a single component, and simultaneously, the gasoline can avoid additional pollution on air, prolong service lives of automobile engines, and reduce damage to environment and human; moreover, through the transition metal gasoline antiknock agent, octane number of the gasoline is improved by 3.0-10.0 units, an induction period of the gasoline is prolonged and actual content of colloids is reduced; therefore, quality of a gasoline product is improved.
Description
Technical field
The invention belongs to gasoline dope field, be specifically related to a kind of transition metal type gasoline antiknock.
Background technology
Along with the continuous increase of the fast development of automobile industry and the compression ratio of motor car engine, motor vehicle industry requires specification to become more and more higher to quality of gasoline at present.This is mainly because low octane value gasoline very easily produces pinking, easily jeopardizes the internal structure of engine.In order to address this problem, people add gasoline octane rating improving agent (being commonly called as octane promoter) in base gasoline, and this additive can effectively improve the octane value of base gasoline.This method is widely used because of easy and simple to handle and economical and effective.
In recent years, the octane promoter using is both at home and abroad divided into two kinds by the application characteristic of gasoline antiknock, be respectively metal and have grey class and organic ashless class, and metal has grey class to have very important effect in oil refining industry, development prospect is boundless, the lead alkyl antiknocks that 20 beginnings of the century were found, because of its preparation technology simple, effect is remarkable, the advantage such as with low cost and being widely used, but itself there is extremely strong toxicity, and in the process of gasoline combustion, generate lead compound particle and can make the poisoning of catalyst of automobile exhaust purifier, and finally exit the market of octane promoter.In mid-term in 20th century, along with eliminating of organometallic lead antiknock compound, ferrocene octane promoter starts to progress into people's the eye of looking, and is mainly because it has the pressure that can reduce in cylinder, the advantage such as rate of heat release peak value and less topsoil that reduces Fuel Petroleum.But in the process that uses the type detonator, find that it has increased the load of engine, cause its scope of application to narrow.
Summary of the invention
The invention provides a kind of transition metal type gasoline antiknock, the octane value that its object is to solve existing gasoline antiknock is lower, and fuel performance is not high, and the poisonous defect of tail gas of discharge after burning.
Technical scheme of the present invention is such:
A kind of transition metal type gasoline antiknock, is made up of manganese metallorganics and aromatic amine compounds, and taking overall weight part as 10000, the content of each component is respectively: described manganese metallorganics is 4-16 part, and described aromatic amine compounds is 99996-99984 part.
Further: described manganese metallorganics is 8-14 part; Described aromatic amine compounds is 99992-99986 part.
Further: the organic group of described manganese metallorganics is C
7-C
15carbonyl, described aromatic amine compounds is by C
1-C
3the aniline that alkyl replaces.
Further: described manganese metallorganics is the one in methyl cyclopentyl-dialkyl-tricarbon manganium (MMT), cyclopentadiene tricarbonyl manganese (CMT) or ten manganese carbonyls.
Further: described aromatic amine compounds is o-toluidine, m-toluidine, to one or more mixtures in monomethylaniline or 1,3 xylidine.
Beneficial effect of the present invention: a kind of transition metal type gasoline antiknock provided by the invention, it is mainly manganese metallorganics with aromatic amine compounds with different mass than composite and obtain.In gasoline, add this transition metal type gasoline antiknock, because the sedimentation manganese metallographic phase producing after fuel combustion is few more a lot of than the octane promoter of the manganese metallorganics of one-component, so to sparking plug, the impact of engine is less, can not cause extra pollution to air simultaneously, can extend the work-ing life of motor car engine, reduce the infringement to environment and human body, and this transition metal type gasoline antiknock can improve a gasoline octane rating 3.0-10.0 unit, can extend the content of induction period of gasoline and reduction existent gum, thereby promote the quality of gasoline products.If add the transition metal type gasoline antiknock described in 1.5% in same gasoline, it can improve 3.4 units of gasoline octane rating, if when addition is 3%, can improve 6.7 units of gasoline octane rating.Described aromatic amine compounds is o-toluidine, m-toluidine, to one or more mixtures in monomethylaniline or 1,3 xylidine.Synergy between aromatic amine compounds and manganese metallorganics is stronger, while synergy is between the two also to carry high-octane positive cooperativity, by adjusting the quality proportioning between the two, can effectively improve the octane value of gasoline, simultaneously less on the impact of gasoline quality, as the project indicator such as existent gum, inductive phase.
