Problems solved by technology

Polyisobutylamine is the main representative detergent, which has an excellent cleaning effect on fuel nozzles and intake valve carbon deposits, but because it is too difficult to decompose, it is easy to increase the generation of carbon deposits in the combustion chamber; polyetheramine detergents are effective in inhibiting combustion Chamber carbon has a unique effect, and its cleaning effect on high-temperature components is not as good as that of the third-generation detergent

preparation example Construction

[0030] The preparation method of described ureido carbamate is as follows:

[0031] Put 38g of toluene diisocyanate (TDI) into a fully dried four-necked flask, and after heating up to a reaction temperature of 80°C, add 85g of isoprene glycol and octylamine, and stir and react for 3 to 4 hours under the protection of nitrogen. Rapidly cool down to below -5°C, and determine that the NCO% reaches the theoretical value of 0-0.06% (mass ratio), and the product is obtained, and the molar ratio of isoprene glycol and octylamine is 1:1.

[0032] In some embodiments, the weight ratio between the amino acid ester and the fatty acid alkyl alcohol ester is 1: (0.5-1.5); preferably, the weight ratio between the amino acid ester and the fatty acid alkyl alcohol ester The weight ratio is 1:(0.8-1.2); more preferably, the weight ratio between the amino acid ester and the fatty acid alkyl alcohol ester is 1:1.

Abstract

The invention relates to the field of fuel cleaning agents, and provides a cleaning agent suitable for liquid fuel. The cleaning at least comprises raw materials of vegetable oil, fatty acid alkyl alcohol ester and amino acid ester, wherein the total number of carbon atoms in the fatty acid alkyl alcohol ester is no more than 44. The invention also provides a preparation method of the cleaning agent. The preparation method at least comprises the following steps: (1) adding the vegetable oil and the amino acid ester into a reaction kettle and mixing uniformly; (2) adding the fatty acid alkyl alcohol ester and stirring uniformly; and (3) finally adding cyclodextrin, and filtering by using a filter of 5 [mu]m to obtain the cleaning agent.

Description

technical field [0001] The invention relates to the field of fuel detergents, and more particularly to a detergent suitable for liquid fuels and a preparation method thereof. Background technique [0002] The number of automobiles in our country is increasing rapidly, and the environmental pollution caused by the combustion and emission of fossil fuels cannot be ignored. During the operation of the car, the deposits produced by the engine intake system and the combustion chamber will seriously affect the normal injection, atomization, mixing and combustion of fuel, which will make the driving performance of the car engine worse, the power and fuel economy will be reduced, and the emission will deteriorate , destroy the environment. At present, gasoline locomotives used in our country, especially small cars, mainly use electronically controlled fuel direct injection technology in their engines. The application of this technology puts forward higher requirements on the quali...
