Embodiment 1

[0033] Use the p-methylaniline polyoxypropylene ether obtained in Synthesis Example 1 to compound with antioxidants, rust inhibitors, corrosion inhibitors and cosolvents. The mass ratio of each component is: 65.0% p-methylaniline Polyoxypropylene ether, 2.5% T502, 1.5% T747, 1.0% T551 and 34.0% aromatic oil.

[0034] The above components are measured according to the proportions to be added, mixed and stirred uniformly at room temperature until transparent, and filtered to obtain the gasoline detergent of the present invention. The gasoline detergent of the present invention is added to the commercial 93# gasoline at a dose of 600ppm. After evaluation by professional departments, the physical and chemical indexes of the oil meet the requirements of GB17930-2006. According to the GB / T19230.4 test method, the reduction rate of deposits generated by the intake valve of the automobile is simulated, and the change of the deposit increase in the combustion chamber of the automobile eng...

Embodiment 2

[0036] The 3-tert-butylaniline polyoxypropylene ether obtained in Synthesis Example 2 is compounded with antioxidants, rust inhibitors, corrosion inhibitors and cosolvents. The mass ratio of each component is: 70.0% 3-tert-butyl Base aniline polyoxypropylene ether, 2.5% T502, 1.5% T747, 1.5% T551 and 24.5% aromatic oil. Repeat the preparation method of Example 1 to obtain the gasoline detergent of the present invention.

[0037] The gasoline detergent of the present invention is added to the commercial 93# gasoline at a dosage of 700 ppm. After evaluation by the professional department, the physical and chemical indexes of the oil meet the requirements of GB17930-2006. According to the GB / T19230.4 test method, the reduction rate of deposits generated by the intake valve of the automobile is simulated, and the change of the deposit increase in the combustion chamber of the automobile engine is simulated by the thermogravimetric analyzer. After testing, the simulated intake valve ...

Embodiment 3

[0039] The 3-tert-butylaniline polyoxypropylene ether obtained in Synthesis Example 2 is compounded with antioxidants, rust inhibitors, corrosion inhibitors and cosolvents. The mass ratio of each component is: 80.0% 3-tert-butyl Base aniline polyoxypropylene ether, 2.5% T502, 1.5% T706, 1.0% T551 and 15.0% aromatic oil. Repeat the preparation method of Example 1 to obtain the gasoline detergent of the present invention.

[0040] The gasoline detergent of the present invention is added to the commercial 93# gasoline at a dosage of 800ppm. After evaluation by the professional department, the physical and chemical indexes of the oil meet the requirements of GB17930-2006. According to the GB / T19230.4 test method, the reduction rate of deposits generated by the intake valve of the automobile is simulated, and the change of the deposit increase in the combustion chamber of the automobile engine is simulated by the thermogravimetric analyzer. After testing, the simulated intake valve s...

Abstract

The invention relates to a gasoline detergent prepared from aromatic amine polyoxypropylene ether. The aromatic amine polyoxypropylene ether is represented by a structural formula (I), wherein R is hydrogen or an alkyl group of C1 to C10, and can be positioned at an ortho-position, a meta-position or a para-position on a benzene ring relative to nitrogen atoms; and the summation of a and b is a natural number in the range of 9 to 33. When used in gasoline, the gasoline detergent prepared from the aromatic amine polyoxypropylene ether serving as a main component can remarkably reduce the generation of sediments in fuel-intake system of a gasoline engine.

Description

Technical field [0001] The invention relates to a gasoline detergent prepared with aromatic amine polyoxypropylene ether, and also relates to a synthesis method of aromatic amine polyoxypropylene ether. Background technique [0002] Aromatic amine polyoxypropylene ether is a kind of polyetheramine, which belongs to tertiary amine type polyetheramine. It can be used in epoxy resin accelerated curing, bonding, textile dyeing aid, ink and pigment dispersion, etc. Because the aromatic amine polyoxypropylene ether has excellent surface activity and oil solubility, and is not easy to generate deposits and gums at high temperatures, it can be used as the main component of automotive gasoline detergent. [0003] The detergent used in automotive gasoline can inhibit and remove the formation of deposits in the fuel intake system of gasoline engines, and can maintain and restore the fuel intake system of the car engine to the state of a new car as much as possible, thereby achieving relative...
