Embodiment 1

[0043] Take the raw materials according to the following weight ratio:

[0044] α-Methylaniline 81 kg

[0045] Methyl tert-butyl ether (MTBE) 15 kg

[0046] Toluene 2 kg

[0047] Straight-run gasoline 0.9 kg

[0048] Raffinate oil 0.9 kg

[0049] 2.6-di-tert-butyl-p-cresol 0.1 kg

[0050] The method for preparing antiknock agent of the present invention is as follows:

[0051] 1. Firstly, straight-run gasoline and raffinate are mixed to make uniform mixed hydrocarbons.

[0052] 2. Dissolve 2.6-di-tert-butyl-p-cresol in the above-mentioned mixed hydrocarbons, and form a solution of 2.6-di-tert-butyl-p-cresol after fully dissolving.

[0053] 3. Pour α-methylaniline into the synthesis tank,

[0054] 4. Pour toluene and methyl tert-butyl ether (MTBE) into the synthesis tank in turn, stir evenly,

[0055] 5. Pour the solution of 2.6-di-tert-butyl-p-cresol into the synthesis tank and stir evenly to make this product.

[0056] The whole operation process is carried out in a ...

Abstract

The anti-knocking agent for gasoline is made up by using (by weight portion) alpha-methylaniline 46-81 portions, methyl tert-butyl ether (MTBE) 15-50 portions, toluene 2-4 portions, distilled gasoline 0.9-1.5 portions, raffinate oil 0.9-1.5 portions and 2,6-di-tert-butyl-p-cresol 0.1-0.6 portions and uniformly mixing them at plus or minus 35 deg.C and normal pressure. Said invented product can raise octane value of gasoline, and solve the knocking problem of gasoline when it is combusted.

Description

[0001] Field [0002] The gasoline antiknock agent and its preparation method involved in the invention belong to a kind of chemical additive of gasoline. Background technique [0003] The detonation combustion of gasoline in the engine cylinder will cause the temperature of the cylinder to rise sharply, resulting in extremely high pressure and vibration, which will damage the machine parts. To solve the knocking problem when gasoline is burned in the cylinder, it is necessary to increase the octane number of gasoline. There are currently three ways to increase the octane rating of gasoline. One is that oil refining enterprises improve the process configuration of oil refining production, such as the use of platinum reforming, alkylation and other processing technologies. This method increases equipment investment and cost due to the change of process configuration. The second is to add components with high octane number to the oil and choose the best blending scheme. The h...
