preparation example Construction

[0016] The present invention also provides a method for preparing the above gasoline detergent, which includes mixing high surface-active polyetheramine, gasoline octane number improver and alkane solvent oil at room temperature or not exceeding 60°C. The preparation equipment and process can adopt conventional processes. The improvement of the present invention is that the composition of gasoline detergent is different, and there is no restriction on mixing. Preferably, it can be specifically that the reactor, such as a blender, is cleaned first, and the octane of gasoline is removed. The value improver and mineral spirits are added to the blending kettle, then polyetheramine is added, and the mixture is stirred and mixed uniformly at room temperature or under the condition of not exceeding 60°C.

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

Embodiment 1

[0020] Clean the blending kettle, add 5vol% octane 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), stir and mix well at room temperature to obtain gasoline detergent sample S1.

Embodiment 2

[0022] The gasoline detergent sample S2 was prepared by the same method 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 uses thereof. Background technique [0002] With the rapid development of the automobile industry, the number of automobiles in my 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 substances in exhaust gas. How to keep the car engine in a good working condition for a long time, make the fuel gasoline fully burn, reduce fuel consumption and improve emissions. This requires the fuel intake system of the automobile engine to be kept clean for a long time. For this reason, the national environmental protection standards clearly stipulate that effective gasoline detergents must be added to motor gasoline. [0003] Moreover, in modern automobile technology, the fuel electronic injection system (PFI) has completely replaced the car with carburetor, and the dire...
