Problems solved by technology

With the process of unleaded gasoline, people began to use MTBE to blend gasoline in large quantities, but MTBE is an oxygen-containing compound, which can lead to an increase in the emission of nitrogen oxides in exhaust pollutants: MTBE itself has a low calorific value, and a large proportion of addition will make The dynamic performance of the vehicle cannot be fully utilized

Abstract

The invention relates to a gasoline anti-knock additive and its preparation method and belongs to the field of petrochemical industry. The gasoline anti-knock additive is prepared by using the following ingredients: 15-25% of toluene, 10-15% of ortho-toluidine, 5-10% of methylcyclopentadienyl manganese tricarbonyl, 12.5-20% of isobutyl acetate, 20-35% of methyl tert butyl ether and 10-15% of diisobutylene. The preparation technology is simple, and the gasoline anti-knock additive can be prepared only by using one reactor. When the gasoline anti-knock additive is combusted, there is no sediment or residue and efficiency is high. In addition, the preparation technology is simple and the whole process is carried out in the same reactor.

Description

Technical field: [0001] The invention belongs to the field of petrochemical industry, in particular to a gasoline antiknock additive. Background technique: [0002] An important indicator of motor gasoline grade is the octane number of gasoline. When the octane number of gasoline is low, it will lead to asynchronous combustion of the oil-air mixture in the engine, that is, two or more abnormal combustions of asynchronous explosive combustion will occur during the combustion process of the engine, and collisions will occur inside the cylinder due to severe gas vibration. Knocking sound, that is, the phenomenon of "knock combustion" of the gasoline engine occurs, referred to as knock. Obviously, knocking is an abnormal combustion phenomenon of bad oil, which not only reduces the performance of the engine, but also causes damage and early failure to engine parts. [0003] Process method and blending method are the main means to increase octane number, but there are problems s...
