Embodiment 1

[0063] Embodiment 1: the preparation of antiknock agent

[0064] Add 100kg of p-aminoanisole and 400kg of styrene into a reaction kettle equipped with a mechanical stirrer, a thermometer, an addition funnel and a condenser tube, heat up to 60°C, stir for 1 hour, and cool to room temperature to obtain a gasoline antiknock agent.

[0065] Add 0.5ml of the above-mentioned antiknock agent to 99.5ml of 92# base gasoline, test according to GB / T5487 gasoline octane number determination method (research method), and record the RON octane number of gasoline from 92.5 to 93.5.

Embodiment 2-6

[0066] Embodiment 2-6: the preparation of antiknock agent

[0067] Adopt the equipment and steps of embodiment 1, adjust the component of antiknock agent, content, addition amount, stirring temperature and stirring time, prepare the antiknock agent of embodiment 2-6.

[0068] The above parameters and RON values ​​are summarized in Table 1 below.

[0069] Table 1: Preparation parameters and RON promotion results of the antiknock agents of Examples 1-6

[0070]

[0071]

[0072] Note: the RON of the blank gasoline of the above-mentioned embodiments 1-6 is 92.5.

[0073] From the data of Examples 1-6 combined with other experiments done by the inventors, it can be seen that the synergistic effect of (N-methyl) p-aminobenzidine / diethyl ether and styrene / indene is obvious. If the gasoline RON needs to be increased by about 1 point, it is more appropriate to add 0.5v% p-aminoanisole compound antiknock agent; if it needs to be increased by about 3 points, then add N-methyl ...

Embodiment 7

[0082] Embodiment 7: the impact of different antiknock agent additions on RON

[0083] The antiknock agent that embodiment 1 obtains joins in 92# base gasoline with the volume percentage of 0.2%, 0.4%, 0.6%, 0.8%, 1.0% and 1.5%, and the octane number change of gasoline is shown in table 3 below.

[0084] Table 3: Effect of different antiknock agent additions on RON

[0085] The amount of antiknock agent added, v% 0 (blank) 0.2 0.4 0.6 0.8 1.0 1.5 RON 92.5 92.9 93.6 93.9 94.0 94.0 94.1

[0086] figure 1 The data listed in Table 3 are shown. It can be seen that the addition of p-aminoanisole compound antiknock agent in the range of 0.2-0.6v% can significantly improve RON.

Abstract

A fuel antiknock agent and its production method and a fuel composition comprising the fuel antiknock agent, wherein the fuel antiknock agent comprises: (i) one or more compounds of general formula I, wherein R 1 Selected from H or C1-6 alkyl, R 2 selected from C1-8 alkyl; and (ii) one or more compounds of general formula II, wherein, R 3 selected from C2-6 alkenyl, R 4 selected from H or C1-4 alkyl, or R 3 and R 4 Together with the carbon atoms they are attached to form a C5-10 saturated or unsaturated five-, six-, seven- or eight-membered ring, R 5 Selected from H or C1-8 alkyl. For manufacture, the various components are mixed and stirred at a temperature of 50-100° C. for 0.5-3 hours.

Description

technical field [0001] The invention relates to a fuel antiknock agent and a fuel composition, belonging to the field of petrochemical industry. Background technique [0002] As we all know, the most effective way to improve the efficiency of gasoline engines is to increase the compression ratio of the engine, but once the compression ratio is increased, the knocking combustion will be significantly enhanced, and it is necessary to use gasoline with a higher octane number to reduce knocking. The methods to increase gasoline octane number mainly include catalytic reforming and aromatization technology, as well as etherification, alkylation, isomerization and other processes, or to reconcile gasoline composition, and can also be added by adding gasoline octane number improver (commonly known as anti Explosive agent) to achieve. Because the former involves the improvement of the refining process, there are problems of complex process and huge investment, while the latter is ef...
