The preparation method of high flash point alcohol ether diesel of the present invention is: various raw material is added together shear-mixed in shears and evenly, can obtain high flash point alcohol ether diesel.
The using method of high flash point alcohol ether diesel of the present invention is: directly added in the fuel tank of diesel engine by this alcohol ether diesel, and this alcohol ether diesel can be used in combination in any ratio with ordinary diesel oil.
The present invention selects polymethoxy dimethyl ether DMM
3 ~ 8for main raw material.Polymethoxy dimethyl ether is a class lower molecular weight acetals polymkeric substance, and its general formula is expressed as: CH

3n value be 3 ~ 8, wherein n=3 ~ 5 are best.The oligopolymer of n=2 and the compound (methylal) of n=1, its boiling point and flash-point on the low side, therefore as diesel-dope Shortcomings, and the oligopolymer that n is greater than 8, tend to crystallization at low temperatures, therefore should not as diesel-dope.But when n=3 ~ 5, cetane value is up to 78 ~ 100, if directly join in diesel oil, amount very little its advantage applies not out, if measure larger, can cause the cetane value in diesel oil too high, easily causes and burns instantaneously too soon, produce a large amount of cigarette carbon, run counter to desire.Therefore, final choice polymethoxy dimethyl ether DMM of the present invention
3 ~ 8.
In the present invention, the effect of ethylene glycol ethyl ether is: be mainly used as solvent, emulsifying agent, stablizer, extraction agent, softening agent etc.Alcohol ether diesel is agricultural in using occupies very large ratio, and in storage, comparatively alcohol ether gasoline is much safe again, is easy to people is benumbed, mismanagement.Like this, ethylene glycol ethyl ether both can prevent the alcohol ether diesel contingent water absorbability in transport, storage, use procedure because class alcohol more vivaciously causes, and contingent chance water stratification problem, affects the use properties of alcohol ether diesel; The effect of softening agent can be taken into account again, slow down the extracting of alcohols to softening agent in caulking gum in engine.Also can act synergistically with other additive in the lump, Overlay is obvious.
As alcohols, no matter be low-carbon alcohol or higher alcohols, its flash-point is not high, or even very low.The present invention finds when actual production higher alcohols, by some higher alcohols as after 2-amylalcohol, propyl carbinol, 2-methyl butanol, cyclopentanol, Pentyl alcohol and 2-hexanol mix in proportion, the alcohol mixture of higher flash point can be obtained, solve the general not high problem of mixed alcohols flash-point, this problem is also the root problem that most alcohol ethers Flash Point of Diesel is not high.
Meanwhile, when the alcohol mixture that the present invention selects adds in diesel oil, without the need to considering the problem of dissolving each other of diesel oil and alcohol mixture, because in alcohols, carbon atom quantity is larger, the mixing oil distillation curve of alcohol and diesel oil is more close to the distillation curve of diesel oil, and that is, the physical property of higher alcohols is closer to diesel oil.Due to the alcohol mixture price comparatively cheap nearly 1,000 yuan of diesel oil, alcohol ether diesel is made also to have certain economy.Also overcoming general alcohol ether diesel is in ordinary diesel oil, add the suitable low-carbon alcohol of usage quantity and solubility promoter, because the price of solubility promoter is far above low-carbon alcohol, just makes alcohol ether diesel without price advantage.The more important thing is that alcohol mixture has oleophylic and hydrophilic radical, utilize surfactivity to make the phase system of alcohol ether diesel more stable, its resisting phase separation ability strengthens greatly, and the ability that especially water resistant is separated can reach 3%, and this is that a lot of alcohol ether diesel is difficult to accomplish.Nonetheless, if consider that diesel oil is in use mixed into moisture, due to the existence of moisture, will the acid corrosion of activator metal and galvanic corrosion, when in diesel oil during moisture-free, acid attack is very weak, the mainly copper corrosion that causes of active sulfide, and the existence of water in alcohol ether diesel, will cause the ionization of acid, the acid corrosion of active metal is aggravated, and activates other corrosion behaviors.The present invention finds after test of many times, and the mixture of ethanamide, 1,2,3-benzotriazole, Berberine can make the problems referred to above be alleviated.Wherein, ethanamide is the fine solvent of gas chromatography and inorganics, is also widely used as the stablizer of softening agent, also for moisture adsorbent processed, lubricant etc.; 1,2,3-benzotriazole, is applied to rust-preventive agent, deicing fluid, oils oxidation inhibitor (various lubricating oil, hydraulic efficiency oil, brake solution, transformer oil), emulsifying agent, copper ore floatation agent and metal inhibitor; Berberine is that heterogeneous ring compound is adsorbed on metal coating surface by unimolecular layer, chemisorption mode, forms layer protecting film at coating surface, thus retardance acid solution is to the corrosion of coating, plays the effect on protective coating surface.
The present invention utilizes ether, alcohol excellent, shortcoming separately, and adds additive, by maximizing favourable factors and minimizing unfavourable ones, play organic synergy, when both having solved polymethoxy dimethyl ether as additive, the problem of addition, solves again the too high disadvantageous problem causing burning too fast of cetane value.Solve again the problem that in traditional alcohol ether diesel, after oleyl alcohol mixing, flash-point is not high simultaneously.So, the alcohol ether diesel of such blending, on using function, on exhaust emissions, on resisting phase separation, (general alcohol ethers diesel oil low-carbon alcohol is too many, the poor stability of phase), store use safety first-class leading indicator can close to or be better than GB diesel oil GB252-2011 standard-required, be desirable automobile-used clean energy.
The present invention compared with prior art has the following advantages:
1, the flash-point of alcohol ether diesel of the present invention is high, is not less than 55 DEG C, and general alcohol ether diesel, flash-point, generally not higher than 25 DEG C, is mostly met naked light in room temperature and is namely dodged;
2, the discharge of alcohol ether diesel of the present invention is cleaned, and after producing in proportion, quality product can upgrade to state I V standard by state III diesel oil;
3, the powerful of alcohol ether diesel of the present invention, cold start-up is normal, significantly reduces condensation point of diesel oil, improves combustioncharacteristics, improves thermo-efficiency;
4, alcohol ether diesel of the present invention can make smoke intensity reduce by 80%, and oxynitride can reduce by 50%, and sulphur content reduces obviously;
5, when the water content of alcohol ether diesel of the present invention does not surpass 3%, not stratified;
6, the temperature lower (generally below-17 ~-18 DEG C) that is separated of alcohol ether diesel of the present invention, its resisting phase separation excellent property;
7, the prices of raw and semifnished materials such as alcohol mixture, polymethoxy dimethyl ether that adopt of alcohol ether diesel of the present invention are all lower than diesel-fuel price, have quite significant economy.
In a word, alcohol ether diesel of the present invention is while guarantee reaches more than 55 DEG C high flash point, and other main physical and chemical index can reach or be better than GB diesel oil GB252-2011 standard-required.Overcome traditional alcohol ethers diesel oil or fuel to cause because flash-point is too low storing, transport, use dangerous, not have practicality shortcoming.Because added polymethoxy dimethyl ether is (increase the oxygen level of diesel oil containing oxygen agent, the soot that burning can be made to produce and particulate matter fewer than pure diesel oil), high hexadecane value agent (cetane value when its n is 3,4,5 reaches 78 ~ 100), and to have and the advantage such as diesel oil mutual solubility is good; Added alcohol mixture is except flash-point is higher, and clean fuel especially, burning only produces CO
2and water; Therefore, prepared alcohol ether diesel discharge is few, and PM particle is less, is conducive to environmental protect, and administering atmospheric haze, is one of current clean fuel oil with actual application value.
Below in conjunction with embodiment, the present invention is described in further detail.
