Problems solved by technology

The process of preparing polyisobutylene amine by chlorination is simple, but it will inevitably leave a small amount of chlorine in the product, which will easily cause secondary pollution to the environment
[0007] U.S. Patents US5567845 and US5124484 utilize hydroformylation reactions to prepare polyisobutylene amines, and no toxic Cl is used in the production process 2 , the product does not contain chlorine, but the reaction requires noble metals as catalysts and must be carried out under very high pressure, the reaction system is very viscous, and it is difficult to achieve catalyst regeneration

example 1

[0047] Add 93 grams of aniline, 1000 grams of highly active polyisobutylene (molecular weight 1000), 30 grams of boron trifluoride ether and 300 ml of mixed trimethylbenzene into the enamel reaction kettle, replace the air in the reaction kettle with nitrogen, heat up to 150 ° C and stir 8 hours. After the reaction was completed, cool to room temperature, add 8 grams of butanol, neutralize with excess NaOH and wash with water to pH=8~10, anhydrous NaOH 2 SO 4 After drying and filtering, the filtrate was distilled under reduced pressure to remove the solvent and other low boilers to obtain 1028 g of the product.

example 2

[0049] 137 grams of N-phenylethanolamine, 1000 grams of highly active polyisobutylene (molecular weight 1000), 40 grams of boron trifluoride ether and 450 milliliters of heavy aromatics are added in the enamel reaction kettle, and the air in the reaction kettle is replaced with nitrogen, and the temperature is raised to Stir at 170°C for 10 hours. After the reaction is completed, cool to room temperature, add 15 grams of polyoxyethylene polyoxypropylene polyether, neutralize with excess NaOH and wash with water to pH = 8 ~ 10, anhydrous Na 2 SO 4 After drying and filtering, the filtrate was distilled under reduced pressure to remove the solvent and other low boilers to obtain 1095 g of the product.

example 3

[0051]Add 137 grams of N-phenylethylenediamine, 1000 grams of highly active polyisobutylene (molecular weight 1000), 30 grams of boron trifluoride ether and 350 milliliters of mixed trimethylbenzene into the enamel reaction kettle, and replace the air in the reaction kettle with nitrogen , heated to 160°C and stirred for 8 hours. After the reaction was completed, cool to room temperature, add 10 g of butanol, neutralize with excess KOH and wash with water to pH = 8-10, anhydrous Na 2 SO 4 After drying and filtering, the filtrate was distilled under reduced pressure to remove the solvent and other low boilers to obtain 1082 g of the product.

Abstract

The invention relates to novel polyisobutene amine used as a gasoline cleansing agent and a synthetic method of novel polyisobutene amine. Polyisobutene amine can be represented as the general formula shown in the specification, in the formula, n is the repeating unit number of a polyisobutene chain segment, and X is an organic group containing amino. Polyisobutene amine is prepared from high-activity polyisobutene and aminobenze through a Friedel-Crafts alkylation reaction by one step, the synthesis process is simple, the production cost is low, the product yield is high, high pressure and a noble metal catalyst used in a traditional production process of polyisobutene amine are avoided, and good application prospect is realized.

Description

technical field [0001] The invention relates to a novel polyisobutene amine used as a gasoline detergent and a synthesis method thereof, belonging to the field of petrochemical industry. Background technique [0002] At present, the olefin content in my country's motor gasoline is relatively high (the olefin content is 30-50%), which is much higher than the motor gasoline standards of developed countries such as Europe, America and Japan. Due to the high working temperature at the engine nozzle and intake valve, unstable components such as olefins (especially diolefins) in gasoline are prone to oxidation and condensation reactions, and under the combined action of other impurities in gasoline, the final product Forms of carbon are deposited in critical parts of the engine. The existence of carbon deposits will lead to the deterioration of gasoline combustion process, increased fuel consumption, reduced engine power and performance, and increased emissions of exhaust polluta...
