Abstract

The invention discloses a high-concentration gasoline detergent and a preparation process thereof. The high-concentration gasoline detergent comprises polyether amine, polyisobutylene amine, di-tert-butyl-p-methylphenol, bis(salicylidene)propane diamine, benzotriazole, xylene, aviation kerosene, n-butyl alcohol, isopropanol and SP demulsifying agents, and the weight percentages of the components are as the follows: 15-25% of the polyether amine, 25-35% of the polyisobutylene amine, 0.5-1% of the di-tert-butyl-p-methylphenol, 0.5-1% of the bis(salicylidene) propane diamine, 0.5-1% of the benzotriazole, 1-10% of the xylene, 15-25% of the aviation kerosene, 3-8% of the n-butyl alcohol, 5-10% of the isooctanol and 2-5% of the demulsifier SP. The preparation process comprises the following steps: step 1, selecting materials; step 2, carrying out mixing; step 3, carrying out concentrating; step 4, adjusting the pH value; and step 5, carrying out discharging. The high-concentration gasoline detergent can be used for replacing other expensive gasoline detergents, the concentration degree is high, the use amount is low, the effect is remarkable, the raw materials are relatively cheap, production cost is greatly saved, sediments at oil nozzles and sediments at air inlet valves can be removed, and meanwhile, formation of combustion chamber deposits (CCD) are reduced, so that secondary pollution of existing detergents is avoided.
