[0037] The preparation method of 3-phenyl-1-(2-amino-3,4,5-trimethoxy-phenyl) propenone at least comprises the following steps:

[0038] 0.8 mol of acetophenone and 0.7 mol of 2'-amino-3',4',5'-trimethoxyacetophenone were added to 0.8 ml of methanol in which 0.7 mol of cinnamaldehyde was dissolved. Add 0.4 mL of 6 mol / L sodium hydroxide solution to it, stir for 40 min, and refrigerate overnight. Filter, wash with ice water and methanol until neutral, and the methanol needs to be refrigerated for more than 12 hours before use. Purified by recrystallization to obtain 3-phenyl-1-(2-amino-3,4,5-trimethoxy-phenyl)propenone.

The environmentally-friendly energy-saving emission reduction gasoline additive is prepared from the following ingredients in parts by weight: 4-9 parts of ethyl tert butyl ether, 2-5 parts of dimethyl carbonate,1-3 parts of 3-phenyl-1-(2-amino-3,4,5-triethoxy-phenyl)acrylketone, 2-6 parts of 3,4,5-trihydroxy benzene formamide, 3-9 parts of 1-(4-hydroxy phenyl)-5-sulfydryl-tetrazole, 1-5 parts of benzotriazole, 4-8 parts of ethyl acetate, 2-5 parts of triethanolamine, 11-15 parts of isopentyldiol and 14-30 parts of solvent.

Description

technical field [0001] The invention relates to the field of gasoline additives, in particular to an environmentally friendly energy-saving and emission-reducing gasoline additive and a preparation method thereof. Background technique [0002] Gasoline is a transparent liquid, flammable, with a distillation range of 30°C to 220°C, and its main components are C5-C12 aliphatic hydrocarbons and naphthenes and a certain amount of aromatic hydrocarbons. Gasoline is obtained by refining straight-run gasoline components, catalytically cracked gasoline components, catalytically reformed gasoline components and other gasoline components, which are refined and blended with gasoline additives. . [0003] Gasoline additives are also known as "fuel treasures" on the market, also known as fuel additives, fuel-saving additives, gasoline detergents, etc. Simply put, gasoline additive is a substance added to automobile fuel for the purpose of "energy saving and emission reduction". "Energ...
