preparation example Construction

[0052] The invention provides a kind of preparation method of polyether amine compound, comprises the following steps:

[0053] 1) Under the action of the catalyst, after the dehydrogenation reaction of the gemini polyether alcohol, the gemini polyether ketone is obtained;

[0054] 2) Under the condition of hydrogen, after the gemini polyether ketone obtained in the above steps, the catalyst, calcium oxide and liquid ammonia are subjected to amination reaction, a polyetheramine compound having a structure shown in formula I is obtained;

[0055]

[0056] Wherein, the m=3-10, n=3-10, x=5-15, y=5-15.

[0057] In the above-mentioned preparation method of the present invention, the structure of the material, the selection of parameters and the preferred range thereof are consistent with those of the aforementioned polyetheramine compounds, and the selection of parameters and the preferred range thereof will not be repeated here.

[0058] In the present invention, firstly, under ...

Embodiment 1

[0086] Add gemini polyether alcohol (wherein, m=4, n=4, x=7, y=8) to the high-temperature and high-pressure reactor, add Raney nickel catalyst accounting for 3% of the mass of gemini polyether alcohol, vacuumize, 235°C After reacting for 19 hours, purging with nitrogen, and then filtering to obtain gemini polyether ketone.

[0087] Add gemini polyether ketone to the high-temperature and high-pressure reaction kettle, add a Raney nickel catalyst accounting for 6% of the mass of gemini polyether ketone, add calcium oxide with twice the molar number of gemini polyether ketone, and vacuumize. Introduce hydrogen gas with twice the mole number of Gemini polyether ketone, add liquid ammonia with twice the mole number of Gemini polyether ketone, recover unreacted hydrogen and ammonia after reacting at 210°C for 8 hours, filter and rotary evaporate to obtain a new type of Gemini polyether amine, Yield 95.2%.

[0088] Add 85% of Shell Heineken synthetic oil, 4.8% of BASF's highly activ...

Abstract

The invention provides a polyether amine compound, which has a structure shown as formula I, wherein m=3-10, n=3-10, x=5-15, y=5-15. The invention provides a novel polyether amine compound, special Gemini polyether amine with a structure shown as formula I is adopted as the cleaning agent, and a specific formula and other assistants are supplemented to prepare the gasoline detergent. The gasolinedetergent provided by the invention still can effectively control the formation of intake valve deposits under the condition of a small dosage, improves the problems of difficult start-up, unstable idling speed, difficult acceleration and the like of engines, also can avoid corrosion and save fuel, thereby realizing the optimum performance of engines. The gasoline detergent provided by the invention has the advantages of low carbon deposit cleaning cost, good effect at a small dosage, and simple and convenient use.

Description

technical field [0001] The invention belongs to the technical field of gasoline engine detergents, and relates to a polyetheramine compound, a preparation method thereof, and a gasoline detergent, in particular to a gemini polyetheramine, a preparation method thereof, and a gasoline detergent. Background technique [0002] With the rapid development of the automobile industry, the number of automobiles is increasing rapidly. As automobiles bring convenience to people's production and life, they also increase the consumption of petroleum resources and the emission of harmful substances such as exhaust. How to keep the car engine in a good working condition for a long time, so that the fuel gasoline can be fully burned, reduce fuel consumption and improve emissions. This must require the fuel intake system of the car engine to be kept clean for a long time, and the most effective way is to add a detergent to the gasoline. [0003] Gasoline detergent is a compound gasoline ad...
