Problems solved by technology

The former mainly includes alkyl lead, manganese-based compounds (such as methylcyclopentadiene manganese tricarbonyl MMT), iron-based compounds (such as diisobutylene carbonyl iron), mixed rare earth carboxylates and alkali metal organic antiknock agents, Although they can effectively improve the anti-knock performance of gasoline, they have the problem of particulate matter emissions, and developed countries such as Europe and the United States no longer advocate the use of them.

Embodiment 1

[0013] Add 16.2mL of methanol, 30mL of 85% sulfuric acid, 20.3mL of tert-butanol, and 20.3mL of n-pentanol into a three-necked flask equipped with a thermometer and a condenser, raise the temperature to 50°C and stir for 2.2h, then distill at elevated temperature and collect 46-120 The fraction between ℃ was dried with anhydrous magnesium sulfate to obtain 48.3 mL of methyl n-amyl ether / methyl tert-butyl ether mixture.

[0014] Mix the above mixed solution with dimethylaniline at a volume ratio of 1:1 to obtain antiknock detergent 1#.

Embodiment 2

[0016] Add 38.9mL of methanol, 60mL of 85% sulfuric acid, 40.6mL of tert-butanol, and 40.6mL of n-pentanol into a three-necked flask equipped with a thermometer and a condenser, raise the temperature to 52°C and stir for 2.5h, heat up and distill, and collect 48-120 The fraction between ℃ was dried with anhydrous magnesium sulfate to obtain 98.5 mL of methyl n-amyl ether / methyl tert-butyl ether mixed solution.

[0017] Mix the above mixture with dimethylaniline at a volume ratio of 1:1 to obtain antiknock detergent 2#.

Embodiment 3

[0019] Add 97.2mL of methanol, 90mL of 85% sulfuric acid, 81.2mL of tert-butanol, and 81.2mL of n-pentanol into a three-necked flask equipped with a thermometer and a condenser, raise the temperature to 55°C and stir for 3 hours, heat up and distill, collect 48-122°C The fractions in between were dried with anhydrous magnesium sulfate to obtain 215.1 mL of methyl n-amyl ether / methyl tert-butyl ether mixture.

[0020] Mix the above mixed solution with dimethylaniline at a volume ratio of 1:1 to obtain antiknock detergent 3#.

Abstract

The invention provides an anti-explosion gasoline cleansing agent, which is prepared by compounding methyl amyl ether / methyl tert-butyl ether mixed liquor and dimethylaniline according to the volume ratio of 1:(1-2), wherein the methyl amyl ether / methyl tert-butyl ether mixed liquor is distillate mixed liquor of a product obtained by reacting equal volumes of raw materials tert-butyl alcohol and pentanol with methanol under the catalysis of sulfuric acid. After 0.5 to 1 weight percent of anti-explosion gasoline cleansing agent is added into gasoline, the octane value of the gasoline can be remarkably improved, and high environmental intermiscibility is achieved.

Description

technical field [0001] The invention belongs to the technical field of gasoline additives in petrochemical industry, and relates to a compound preparation for improving gasoline octane number. Background technique [0002] The increasingly serious global environmental pollution has seriously threatened human survival and social development, and environmental problems have become one of the most serious challenges facing society today. Gasoline, as the most important petroleum fuel, contains water and carbon dioxide, as well as carbon monoxide, nitrogen oxides, aromatic hydrocarbons, etc. in the gas emitted from its combustion, all of which will pose hazards to humans, animals and plants to varying degrees. The production of high-quality gasoline is the most effective way to solve environmental problems. The main ways to improve the quality of gasoline include improving the refining process and developing antiknock agents. The former may cause fluctuations in oil prices. Ther...
