Abstract

The invention discloses an isocrotyl acylamide isoheptyl ester composition and a preparation method. The composition comprises tetrahydrofurfuryl alcohol, crotonamide, ethyl acetate, antioxidant and preservative; the preparation method comprises the following steps: weighing the chemical raw materials according to the mass ratio; adding the tetrahydrofurfuryl alcohol to a reaction kettle, vacuumizing and raising the temperature of the reaction kettle to 70-75 DEG C; adding the crotonamide and the ethyl acetate, stirring and cooling by a cooler to about 25 DEG C; and adding 6-di tert butyl paracresol and isothiazole quinoline ketone and stirring so as to obtain a product. The composition has no toxicity, no pollution, no special peculiar smell and little addition quantity, obviously improves the performance of a gasoline octane number promoter, is brown oil transparent liquid, and has the density of 970-990Kg / m<3>, the solidifying point of not higher than -50 DEG C, and the boiling point of 180+ / -5 DEG C. The invention has simple process, low cost, oil saving and pollution reduction, reduces the fuel oil sediment of an engine, lightens the abrasion of the engine and is widely usedfor petrochemicals.

Description

technical field

[0001] The invention relates to an external admixture used in petroleum products, in particular to an isobutenyl amide isoheptyl ester composition and a preparation method. Background technique

[0002] Over the years, manganese-based organic compounds are one of the best quality octane accelerators among many metal and non-metallic octane accelerators, abbreviated as MMT. MMT can effectively increase the octane number in unleaded gasoline, and also reduce engine wear; but its biggest disadvantage is the high cost, about four times that of lead octane boosters, and it also has damage The effect of automobile exhaust purification makes it controversial in use, and more importantly, the octane number can only increase by 2 to 2.5 units after adding it. Long-term use is bound to cause metal accumulation, spark plug failure, shortened exhaust valve life, and increased combustion chamber carbon deposits.

[0003] People are also studying the use of pure organic ...
