Abstract
The preparation method of organic magnesium vanadium-inhibiting agent is characterized by that the neutralization reaction of solvent and magnesium compound is implemented in the presence of catalyst, and after neutralization reaction, in the presence of Co2 the complexation reaction is carried out. As compared with existent technology said invented product does not lump, and when it is used, it does not block gun nozzle, and the guality and property of complex product are stable.
Description
The present invention relates to a kind of fuel oil additive, particularly a kind of when suppressing oil inflame to the additive of surface corrosion of internal combustion turbine metal blade and fouling.
There is following shortcoming in harmful element such as vanadium, sodium to the corrosion disoperation of combustion equipment in the fuel oil though existing oil soluble organic-magnesium vanadium inhibitor can suppress effectively:
1, owing to contain volatile organic solvent, the shelf-time one is long, and additive lumps because of the volatilization of solvent easily, can not use.
2, contained particle is bigger in the additive, stops up gun hole during use easily.
3, chance water reacts and forms gelatin product, can't use.
Goal of the invention of the present invention is to provide that a kind of solvent is not volatile, particles contained little, the stupid water preparation method of the oil soluble organic-magnesium vanadium inhibitor that forms gelatin product that can not react in the additive.
The present invention is achieved in that the preparation that comprises petroleum base sulfonic acid, naphthenic acid, high molecular weight fatty acid, MgO, MgCO
3, MgSO
4And Mg (OH)
2Cleaning, purifying, drying, activation, petroleum base sulfonic acid, naphthenic acid, high molecular weight fatty acid and MgO, MgCO
3, MgSO
4, Mg (OH)
2And organic solvent mixed chemical reaction process, fractionation by distillation, removal of impurities process, its special feature is that organic solvent can be a petroleum alkane, can be aromatic hydrocarbons or both mixing, petroleum base sulfonic acid, naphthenic acid, high molecular weight fatty acid and MgO, MgCO
3, MgSO
4, Mg (OH)
2And organic solvent mixed chemical reaction process be under the effect of catalyzer in and chemical reaction, be at CO then
2Complex reaction under participating in, catalyzer can be an organic multicomponent amine, can be organic acid, can be organic polyhydric alcohol, can be wherein two or three in organic multicomponent amine, organic acid, the organic polyhydric alcohol.
Here, the time of mixed chemical reaction is 3-5 hour, and temperature is 40-80 ℃, normal pressure.
When adopting three kinds of catalyzer simultaneously, the three should be in batches, substep adds.
Catalyst consumption is the 1-5% of material total amount, has so both guaranteed that chemical reaction is abundant, is unlikely to waste expensive catalysts again.
The present invention compared with the prior art, owing to adopted alkane, aromatic hydrocarbons, in mixing He in the chemical reaction, add catalyzer, like this, more complete with chemical reaction in the mixing, organic solvent is not volatile, has made things convenient in fractionation by distillation, removal of impurities operation the macrobead in the work in-process is removed, be difficult for stopping up advantages such as gun hole when making the finished product vanadium-inhibition agent have prevented from caking, use, at CO
2Complex reaction under participating in, the complexing product characteristics that is generated is stable, becomes gelatin material after being difficult for meeting water.
Now in conjunction with the embodiments the present invention is described in further detail:
