The polyether polyamine compound has the characteristics of efficiently clearing deposited carbon of the diesel (gasoline) motor fuel system and thoroughly clearing the deposited carbon of an air intake system and a combustion chamber of a diesel motor. By using the maintenance product for the diesel motor fuel system, the economic efficiency of fuel can be improved, the demounting-free maintenance of the diesel motor can be achieved, the tail gas emission of an automobile is reduced, and energy conservation and environmental protection can be realized.
Description
Technical field
The present invention relates to a kind of polyether polyamine, specifically a kind of polyether polyamine compound and a kind of oil for diesel engine fuel system maintenance article that contain this compound.
Background technology
Along with the continuous development of diesel motor function and perfect, the rotating speed of diesel motor is also increasingly high.Four stroke times of piston motion are also shorter and shorter, how to let diesel oil in the shorter and shorter time, fully burn, and this not only is related to the work-ing life of mover, and are related to the saving of the energy and reduce exhaust gas discharging, thus the protection environment.
Polyetheramine is fuel oil or an oil dope commonly used in the prior art; Be mainly used in the increase of inhibition deposit of gasoline engine combustion chamber and the greasy filth in the lubricant removal; Its function ratio is more single, can not remove the carbon deposit of inside, combustion chamber and nozzle interior effectively.
Summary of the invention
Technical assignment of the present invention is the deficiency to above-mentioned prior art, and a kind of polyether polyamine compound is provided.
The further technical assignment of the present invention provides the compound method of above-mentioned polyether polyamine compound.
The further again technical assignment of the present invention provides a kind of oil for diesel engine fuel system maintenance article that contain above-claimed cpd.
Polyether polyamine compound by following structural formula (I) expression:
The compound method of polyether polyamine compound of the present invention is:
Taking by weighing polyetheramine adds in the reaction vessel; Add a certain amount of triethylamine again, and an amount of 2-chloroethyl amine hydrochloride is added in the flask in batches, stir under the room temperature; After reaction finishes reaction solution is carried out underpressure distillation, purification, promptly get the polyether polyamine compound of structural formula shown in (I).Productive rate is 90%.
In the above-mentioned compound method, the method for purification of polyether polyamine is identical with the method for purification of polyetheramine in the prior art.
Reaction formula is:
A kind of oil for diesel engine fuel system maintenance article are prepared from following materials of weight proportions:
Said polymer detergent-dispersant additive is a polyether polyamine, and the structural formula of said polyether polyamine is:
Said rust-preventive agent preferred alkyl sulphonate.
The preferred polyisobutene of said combustion improver, the molecular weight of said polyisobutene is between 1000 to 3500.
Said sanitas preferred, polyethers polyamines, the structural formula of said polyether polyamine is:
The preferred 124 Triazole verivate of said metal passivator, thiadiazoles derivative and N, a kind of or any several kinds mixture in N` one or the two salicylidene tn.
Said solvent oil be 120# solvent oil, 200# solvent oil, aviation kerosene ,-35# diesel oil ,-40# diesel oil or-in the 50# diesel oil any one.
Polyether polyamine compound of the present invention has the characteristic that can remove diesel oil (gasoline) engine fuel oil system carbon deposit efficiently; Can thoroughly remove diesel motor inlet system and combustion chamber deposit; Be particularly suitable for being used in and do the detergent-dispersant additive use in the fuel oil, solved the problem that the oil for diesel engine fuel system carbon deposit is difficult to remove.
Oil for diesel engine fuel system maintenance article of the present invention focus on it and can make diesel oil more fully burning in the extremely short time.Practice thrift diesel oil, reduced the carbon deposit that engine cylinder and piston and valve place produce because of the diesel oil incomplete combustion.The polymer detergent-dispersant additive cooperates combustion improver, rust-preventive agent and metal passivator etc. efficiently, reaches the multiple maintenance purpose that removing, maintenance combine.
Wherein, The polymer detergent-dispersant additive in use deposits the greasy filth that gets off because of oil oxidation on can clean fuel oil system inwall; Make oil circuit keep unimpeded; And prevent to clear up the greasy filth, the settling that get off and stop up oil circuit with graininess, the greasy filth of clearing up is dissolved in the fuel oil with atomic graininess, thereby has avoided the obstruction of oil circuit.Rust-preventive agent is used for the corrosion of anti-sealing to the prime the fuel system metallic surface.Combustion improver makes in the diesel oil component of high cut fully burn, and has improved the economy of fuel oil.Sanitas is used to prevent that moisture, sulfocompound from causing corrosion to the metal cylinder body.Metal passivator is used to prevent the catalysis and the oxidation of metal pair diesel oil, in the maintenance article, is aided with metal passivator, makes the metallic surface of prime the fuel system be in inactive state, thereby has reduced the catalyzed oxidation of metal pair oil product, stops and reduce the regeneration of new greasy filth.Solvent oil is used to quicken mutual mixing velocity and the homogeneity of these maintenance article to diesel oil.
Pass through probationary certificate; Use oil for diesel engine fuel system maintenance article of the present invention, not only can practice thrift the diesel oil about 3%, and the CO content in the exhaust emissions can reduce more than 10%; The soot particles thing can reduce more than 80%; Dynamic performance has obvious improvement, disassembles clear, and curing time on average can increase more than 3 times.Not only new engine is had obvious effects, improve middle and later periods diesel motor performance aspect have especially outstanding especially and obvious effects.
