preparation example Construction

[0016] The present invention also provides a preparation method for the above-mentioned gasoline detergent, which comprises uniformly mixing high-surface-active polyetheramine, a gasoline octane number improver, and alkane solvent oil at room temperature or at a temperature not exceeding 60°C. The preparation equipment and technology can adopt conventional technology. The improvement of the present invention is that the components of the gasoline detergent are different, and there is no restriction on mixing. In a preferred situation, the reactor such as the blending tank can be cleaned up first, and the gasoline octane Add value improver and solvent naphtha into the blending tank, then add polyether amine, stir and mix evenly at room temperature or not exceeding 60°C.

[0017] The present invention also provides the use of the above-mentioned gasoline detergent, which is added to gasoline at a dosage of 500-2000ppm. Less usage and lower cost. The gasoline detergent of the in...

Embodiment 1

[0020] Clean the blending kettle, add 5vol% octane number improver (methyl tert-butyl ether, Nanjing Fengcheng Chemical Co., Ltd.) and 45Vol% solvent oil (D80, Maoming Petrochemical) into the blending kettle, and then add 50Vol% polyetheramine (Lz9522c from Lubrizol Company), stirred and mixed uniformly at room temperature to obtain gasoline detergent sample S1.

Embodiment 2

[0022] Gasoline detergent sample S2 was prepared in the same manner as in Example 1, except that the amount of polyetheramine was 30 vol%, the amount of gasoline octane improver was 10 vol%, and the amount of mineral spirits was 60 vol%.

Abstract

The invention provides a gasoline detergent, a preparation method, and applications thereof. The gasoline detergent comprises polyether amine with a surface activity, a gasoline octane value improver, and alkane solvent naphtha, wherein by taking the volume percentage of the gasoline detergent as the baseline, the volume percentage of the polyether amine is 30-70 vol%, the volume percentage of the gasoline octane value improver is 3-20 vol%, and the volume percentage of the alkane solvent naphtha is 25-60 vol%. The gasoline detergent can more effectively remove the carbon deposition on the oil nozzle, combustion chamber, and intake valve of a motor, improves the economic profit of fuel combustion, reduces the gasoline consumption, prevents the motor wear, prolong the service life of the motor, and decreases the maintenance fee. The cost of the gasoline detergent is low, because an ideal effect can be achieved by using only a few amount of the gasoline detergent.

Description

technical field [0001] The invention relates to a gasoline detergent, a preparation method and an application thereof. Background technique [0002] With the rapid development of the automobile industry, the number of automobiles in our country is increasing rapidly. As automobiles bring convenience to people's production and life, they also increase the consumption of petroleum resources and the emission of harmful exhaust substances. How to keep the car engine in a good working condition for a long time, so that the fuel gasoline can be fully burned, reduce fuel consumption and improve emissions. This must require the fuel intake system of the automobile engine to be kept clean for a long time. For this reason, it is clearly stipulated in the national environmental protection standard that an effective gasoline detergent must be added in motor gasoline. [0003] Moreover, in modern automobile technology, electronic fuel injection system (PFI) has completely replaced car...
