Abstract
The invention discloses an additive which can stabilize and synergize the effects of a vehicle-used methanol-diesel. The additive is made from preferably selected raw materials and components as follows: isoamyl alcohol, n-heptanol, isopropanol, n-butyl alcohol, OP-15 and di-tert-butyl-4-methylphenol by certain percentage by weight are sequentially driven into a reactor with stirring and circumfluence functions and evenly dispersed by being stirred at a low speed, and mutually and totally dissolved into transparent and stable additive product of the invention. The additive not only solves the difficult problems of the existing methanol-diesel and ensures that the methanol-diesel has excellent water resistance, cold resistance, stability for long term storage and no phenomena of emulsion separation and phase separation when being randomly mixed with commercial gasoline; simultaneously, the additive self also has the function of high octane number and belongs to oxygenated additive which becomes an ideal component of the methanol gasoline and obviously enhances the octane number of the methanol gasoline; the burning is more complete and the pollutant emission of tail gas is reduced and an engine does not need to be modified when the methanol gasoline is used.
Description
Technical field
The invention belongs to the methanol fuel for vehicles technical field, especially relate to a kind of stable synergistic of methanol gasoline for vehicle.
Background technology
From world wide, the disposable energy such as oil, coal will progressively exhaust, the natural rich coal resources of China, but also be limited.Along with China's rapid development of economy, solving alternative and reducing the automobile-used oil fuel of consumption is the ten minutes urgent task.Methyl alcohol is abundant as the source, the relatively low a kind of clean fuel of cost receives global concern.Full methanol fuel exists polarity strong again, and calorific value is low, and incomplete combustion produces shortcomings such as formaldehyde.Thereby methyl alcohol and gasoline mixes burning and can reach and substitute and reduce petrol consumption, can overcome the purpose of the deficiency of itself again.But resolve that methanol gasoline is water-fast, low temperature resistant, prolonged preservation and the problem that is easy to generate emulsus and is separated when being mixed with gasoline.
At present, short with the methanol gasoline quality guaranteed period that existing additive or emulsifying agent are produced, can not standing storage, poor stability, the efficiency of combustion of methanol gasoline can not get improving, and makes methanol gasoline can not satisfy the requirement of motor spirit.
Summary of the invention
Technical problem to be solved by this invention is at above-mentioned deficiency of the prior art, a kind of methanol gasoline steady quality of production is provided, do not produce emulsus when being mixed and be separated the stable synergistic of methanol gasoline for vehicle that the methanol gasoline efficiency of combustion is improved significantly with gasoline.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of stable synergistic of methanol gasoline for vehicle is characterized in that the raw material composition and the weight percent of this additive is:
Primary isoamyl alcohol 15-30% n-Heptyl alcohol 6-15% Virahol 15-25% propyl carbinol 30-55%
OP-15 2-6% ditertbutylparacresol 0.5-3%.
The preferred technical solution of the present invention is: a kind of stable synergistic of methanol gasoline for vehicle is characterized in that the raw material composition and the weight percent of this additive is:
Primary isoamyl alcohol 20% n-Heptyl alcohol 10% Virahol 20% propyl carbinol 46%
OP-15 3% ditertbutylparacresol 1%.
Preparation method of the present invention is: under whipped state, with primary isoamyl alcohol, n-Heptyl alcohol, Virahol, propyl carbinol, OP-15 and ditertbutylparacresol, by above-mentioned weight percent, squeeze into successively in the reactor of band stirring and refluxing, stir at a slow speed at normal temperatures and pressures, make its homodisperse, dissolve fully mutually, make the stable synergistic of methanol gasoline for vehicle of the present invention of transparent and stable.
The present invention compared with prior art has the following advantages: additive of the present invention can make the methyl alcohol of any ratio and commercial gasoline under emulsification, dispersion and the hydrotropy effect of a certain amount of additive product of the present invention, and, make it to form the methanol gasoline product of transparent and stable by the external force stirring; This additive has not only solved methanol gasoline and has had excellent water resistance, lower temperature resistance, extended storage stability, and be mixed down arbitrarily emulsus does not take place with commercial gasoline, a difficult problem that is separated, additive itself has the high-octane rating effect again simultaneously, and belong to oxygen containing additive, become the desirable component of methanol gasoline, make the octane value of methanol gasoline obtain obviously to improve, it is more complete to burn, the exhaust pollutant discharging reduces, impel the advantage of methanol gasoline to obtain to give full play to, shortcoming is effectively suppressed, can accomplish methanol gasoline in use engine need not change, oily station can be refueled arbitrarily.
Below by embodiment technical scheme of the present invention is described in further detail.
