preparation Embodiment 1

[0029] Preparation Example 1 [polyether polyamine compound (structural formula I)]:

[0030] Weigh 27.2.0g (about 0.1mol) of polyetheramine into a three-necked flask, then add a certain amount of triethylamine, and add 13.8g (about 0.12mol) of 2-chloroethylamine hydrochloride into the flask in batches. After the reaction was completed, the reaction liquid was distilled and purified under reduced pressure to obtain 28.8 g of the title compound - polyetherpolyamine, with a yield of 90%.

[0031] The product was analyzed by electrospray mass spectrometry, ESI-MS: 320.84 (measured value); 320.54 (calculated value).

[0032] Product is carried out infrared absorption spectroscopic test, survey result is as follows: 1) in 3400cm -1 There is a broad peak near it, which is caused by -NH stretching vibration; at 3000~2700cm -1 range has a set of steep and strong peaks, which are caused by -CH in the hydrocarbon chain 3 and -CH 2 Caused by stretching vibration; 3) at 1600~1200cm -1...

Abstract

The invention disclose a novel polyether polyamine compound with a structural formula (I) and a synthesis method thereof as well as a maintenance product for a diesel motor fuel system. 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 anda 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 [0001] The invention relates to a polyether polyamine, specifically a polyether polyamine compound and a diesel engine fuel system maintenance product containing the compound. Background technique [0002] With the continuous development and improvement of the functions of diesel engines, the speed of diesel engines is also getting higher and higher. The four-stroke time of piston movement is getting shorter and shorter. How to make diesel fuel fully burn in a shorter and shorter time is not only related to the service life of the engine, but also related to energy saving and reduction of exhaust emissions, thus protecting environment. [0003] Polyetheramine is a fuel or lubricating oil additive commonly used in the prior art. It is mainly used to inhibit the increase of deposits in the combustion chamber of gasoline engines and remove sludge in lubricating oil. Its function is relatively simple and cannot effectively remove the inside of the combustion cha...
