Description
Technical field
The invention belongs to technical field of fine, be specifically related to a kind of gasoline octane rating promotor and preparation method thereof.
Background technology
When gasoline burns in the cylinder, if oily vapour burns, abnormal meeting causes phenomenon of detonation.2 points that have its source in that pinking produces, one is that engine compression ratio is too high, and when combustible oil gas is compressed to cylinder top dead center, temperature is too high; Two is caused by fuel performance.In gasoline, too heavy or some hydrocarbon component is easily oxidized generation superoxide, superoxide not easily decomposes easily coalescent, gasoline spontaneous ignition temperature is reduced cause, before engine spark plug igniting, gas-oil mixture in Piston Compression cylinder, gas volume reduces temperature and rises, and the flame reverse-impact that the gas-oil mixture flame of spontaneous combustion under High Temperature High Pressure and spark ignitor produce, produces random shockwave-pinking.The generation of pinking can cause the sharply rising of cylinder temperature and pressure, and random shock wave produces knock in cylinder wall, and oil gas burning is insufficient, seriously reduces motor efficiency, easily causes internals to damage.
Octane value is the important indicator weighing anti-knock characteristic of gasoline, and octane value its capability of antidetonance higher of gasoline is better.Octane value is not reached to the gasoline of requirement, for reducing or alleviating pinking, artificially can add appropriate octane enhancing additive in gasoline.The mechanism of action of the octane enhancing additive generally admitted at present is: the actives peroxide reactions of the preferential and pre-flame reaction of octane promoter component, impel the decomposition of superoxide, block chain transfer reaction to carry out, thus prolongation decomposition induction time, by the speed control of fuel combustion in normal range, make fuel trim trouble-free burning, avoid pinking.
Since octane enhancing additive comes out, industrial applications is mainly metal grey class and the large class of organic ashless class two.Metal has grey class octane enhancing additive to be the octane enhancing additive product that the mankind use the earliest, with tetraethyllead (TEL), ferrocene, the metal of the Typical Representatives such as methyl cyclopentyl-dialkyl-tricarbon manganium (MMT) has grey class octane enhancing additive to be the octane enhancing additive kind that antiknock efficiency is so far the most excellent, consumption is only ppm rank less, but there is residue problem in life-time service metal species octane enhancing additive, ash content is caused to increase, engine spark plug is caused to block, cylinder body wearing and tearing and the problem such as make the TWC Three Way Catalyst System of vehicle exhaust poisoning, in flue gas, the existence of metal ion is the arch-criminal forming PM glue core.Metal species octane enhancing additive also has larger toxicity (as TEL, MMT etc.) simultaneously, can cause the healthy hidden danger of blood system, endocrine system, reproductive system, now progressively limited or ban use after human contact.Organic ashless class octane enhancing additive mainly oxygen-containing organic compound and organic compounds containing nitrogen: its main representative material has methyl tertiary butyl ether (MTBE), tert amyl methyl ether(TAME), methyl-tert hexyl ether and methyl alcohol, ethanol, methylcarbonate (DMC), methylal, 2-butyl acetate, nitrogen monomethylaniline etc.Compared with metal species octane enhancing additive, the additive capacity of organic ashless class octane enhancing additive is generally relatively large, if MMT additive capacity in gasoline is 10
-6level, and MTBE additive capacity is 10
-1level, 2-butyl acetate addition 10
-2level, finds out that MMT antiknock efficiency is higher than organic ashless additive tens thousand of times more than; Potential threat is there is in the use of organic ashless class octane enhancing additives such as methylal, 2-butyl acetate, nitrogen monomethylaniline to engine.But with metal species octane enhancing additive, organic ashless class octane enhancing additive produces without colloid after having burning, avoid the automobile hardware such as cylinder body wearing and tearing, sparking plug blocking impaired, and make gasoline Thorough combustion, decreasing pollution thing discharges, and uses organic ashless class octane enhancing additive to become the economic effective measure improving anti-knock characteristic of gasoline.Therefore, cleanliness without any pollution in a kind of production process environmental protection, combustion processes is developed and the organic ashless class octane enhancing additive that anti-knocking property are good, addition is few is particularly important.
