Abstract
A kind of preparation method of isooctoate of rare earth metal and application thereof said method comprising the steps of: add a certain amount of isocaprylic acid and basic solution in reactor, stirring reaction carries out saponification; In reaction solution, add aviation kerosene, heat up, when temperature reaches certain value, add the rare earth nitrate salts solution, keep this temperature to react; After certain reaction times, with the reaction solution standing demix, the gained organic layer is the solution that contains isooctoate of rare earth metal.This isooctoate of rare earth metal can be used as the dispersion agent of present commercially available diesel oil.Characteristics of the present invention are that reaction process is simple, and raw material is easy to get, and join in the diesel oil to promote diesel combustion, reduce the generation of carbon deposit in the combustion processes, and can reduce the discharging of environmentally hazardous substance in the motor exhaust.
Description
Technical field
The present invention relates to a kind of preparation method and application thereof of isooctoate of rare earth metal.
Background technology
Along with rapid increase to energy demand, and the increasingly stringent of environmental requirement, diesel oil more and more is subject to people's attention as one of main fuel oil for vehicles.Yet for gasoline cleaning agent, the development of diesel oil detergent is later.Generally speaking, diesel oil detergent is divided into two big classes: grey type purification agent and Ashless type purification agent are arranged.
Having grey type purification agent also to be metal detergent, mainly is the metallorganics of the low strong katalysis of tool of easy betatopic, ionization energy, as organism of Ba, Ca, Mg, K, Fe, Mn, Cu, Ni, C0, Pt metal etc.Metal detergent is the effect highly significant aspect combustion-supporting and smoke elimination, have the katalysis of accelerating the carbon granule oxidation and stop diesel oil under the high temperature anoxic, to be cracked into the anticatalysis effect of carbon granule, can reduce the diesel oil kindling temperature, increase combustionvelocity, promote that diesel oil fully burns, reduce flue dust, SO and NO in the exhaust
xGeneration.
Golothan tests on single-cylinder direct-injection diesel engine and shows, add barium content and be 0.05% grey purification agent is arranged after, smoke intensity descends 40%～50%.
Caton is when having carried out the investigation result at 1900r/min to oil soluble platinum on the single-cylinder direct-injection diesel engine, and CO descends 61%, and HC (total carbon hydrogen richness) descends 68%.
At present, metal mold purification agent on the market all comes with some shortcomings in preparation and application facet, has toxicity as the organic salt of baric, and the organic salt of platinum costs an arm and a leg.So it is very significant developing a kind of cost-effective metal mold purification agent.
Discover that the rare-earth salts of isocaprylic acid also has certain dispersion and combustion-supporting effect.The rare-earth salts of isocaprylic acid has that solvability is good, usage quantity is few, purity is high, of light color, advantage such as smell is light, viscosity is little, and can be used as a kind of dispersion agent adds diesel oil to, and the burning of diesel oil is had good promoter action.
Improve the vehicle fuel quality and reduce emission of harmful substances in the tail gas, mainly solve at present by two kinds of channels: the one, improve petroleum refining process, improve the productive rate of branched paraffin and aromatic hydrocarbons, reduce olefin(e) centent, to improve octane number of fuel oil and antioxidant property; Be to add effective additives on the other hand,, reduce the oil circuit settling to improve efficiency of combustion.The former fund input is big, and the cycle is longer; The latter does not have particular requirement to device, and less investment, instant effect can greatly reduce fuel oil consumption and discharge of harmful gases.Along with constantly increasing the weight of of China's energy and environmental stress, developing efficiently, the metal mold purification agent is very significant.
Summary of the invention
According to an aspect of the present invention, provide a kind of method for preparing isooctoate of rare earth metal, said method comprising the steps of:
A. add a certain amount of isocaprylic acid and basic solution in reactor, stirring reaction carries out saponification;
B. in reaction solution, add aviation kerosene, heat up, when temperature reaches certain value, add the rare earth nitrate salts solution, keep this temperature to react;
C. after certain reaction times, with the reaction solution standing demix, the gained organic layer is the solution that contains isooctoate of rare earth metal.
Wherein, in steps A, described basic solution is preferably potassium hydroxide or sodium hydroxide solution.
In step B, described temperature of reaction is preferably 80 ℃.And isocaprylic acid, potassium hydroxide or sodium hydroxide, rare earth nitrate salt three's mol ratio is 1: 0.6～0.9: 0.2～0.25.
