Problems solved by technology

Alcohol antiknock agents are rarely used in the blending production of gasoline due to poor miscibility with gasoline, large oxygen content and national standard restrictions; the application of ether antiknock agents is more popular, methyl tert-butyl ether ( MTBE) is its main representative, but its oxygen content is too high and its calorific value is low; amine antiknock agents are highly alkaline and prone to corrosion, and because of their high price, there are few market applications; lipid antiknock agents The anti-knock efficiency is low when the agent is used alone, and it is mostly used as an anti-knock agent component.

Embodiment 1

[0025] The preparation method of the gasoline antiknock agent that present embodiment provides is as follows:

[0026] In the mixing tank, add 5-methylenecyclopentadiene, dipropylaminomethyl o-cresol, tert-butanol, polyisobutenylamide isooctyl ester successively, and the mixing ratio is 3:3:2:1 ( weight), after adding one kind of raw material and stirring evenly, another kind is added, and the gasoline antiknock agent is obtained after the above raw materials are fully mixed.

[0027] The gasoline antiknock agent provided in this example should be stored and transported in accordance with the relevant regulations on flammable chemicals, and can usually be packaged in 200L iron drums or special tank trucks for dangerous goods. The gasoline antiknock agent should be kept away from fire sources, strong oxidants, static electricity, etc., and all production equipment and electrical equipment should have explosion-proof functions.

Embodiment 2

[0044] The preparation method of the gasoline antiknock agent that present embodiment provides is as follows:

[0045] In the mixing tank, add 5-methylenecyclopentadiene, dipropylaminomethyl o-cresol, tert-butanol, polyisobutenylamide isooctyl ester successively, and the mixing ratio is 3.5:3.5:2:1 ( weight), after adding one kind of raw material and stirring evenly, another kind is added, and the gasoline antiknock agent is obtained after the above raw materials are fully mixed.

[0046] The gasoline antiknock agent provided in this example should be stored and transported in accordance with the relevant regulations on flammable chemicals, and can usually be packaged in 200L iron drums or special tank trucks for dangerous goods. The gasoline antiknock agent should be kept away from fire sources, strong oxidants, static electricity, etc., and all production equipment and electrical equipment should have explosion-proof functions.

Embodiment 3

[0053] The gasoline antiknock agents and commercially available gasoline antiknock agents in Example 1 and Example 2 were added to the same gasoline oil sample, and the comparison results of the actual colloid and induction period in gasoline are shown in Table 3.

[0054] table 3

[0055]

[0056] As can be seen from Table 3, compared with commercially available antiknock agents, the gasoline antiknock agent provided by the invention can prolong the induction period of gasoline and reduce the content of actual colloid, thereby ensuring the quality of the antiknock gasoline obtained.

Abstract

The invention provides a gasoline antidetonant, a preparing method thereof and antiknock gasoline. The gasoline antidetonant is prepared from 5-methylene cyclopentadiene, Dipropyl aminomethyl o-cresol, tertiary butanol and poly-isobutenyl amide di-iso-octyl sebacate in a weight ratio of 2-4:2-4:1-3:1. The gasoline antidetonant provided by the invention has excellent antiknock performance, does not contain metal and reduces pollution to the environment and harm to a human body, the gasoline antidetonant is simple in production process and low in cost. The antiknock gasoline comprising the gasoline antidetonant has excellent antiknock performance and is non-toxic and environment-friendly.

Description

technical field [0001] The invention relates to a gasoline antiknock agent, a preparation method thereof and antiknock gasoline, belonging to the technical field of petrochemical industry. Background technique [0002] The octane number is the most important quality index of motor gasoline. It comprehensively reflects the level of a country's oil refining industry and vehicle design. Adding antiknock agents to gasoline is an important means to increase the octane number of motor gasoline. Gasoline antiknock agent can improve the antiknock performance of gasoline, that is, the octane number and antiknock index of the research method of the national standard "GB17930-20061" of unleaded gasoline for vehicles, and is the main means of producing high-grade gasoline. [0003] Gasoline antiknock agents can be divided into different types according to their chemical properties. At present, the common ones are mainly metallic and non-metallic antiknock agents. Metallic antiknock age...
