Synthetic example 2

[0029] Preparation of the synthesis reactor: brush the 2L high-pressure reactor with distilled water several times until it is clean, dry the reactor, and lower the temperature to 50-70°C for later use.

[0030] In the first step, 450 g of hexadecylamine was added to the reaction kettle, and after nitrogen replacement twice, the vacuum was drawn while raising the temperature, and when the temperature rose to 130° C., the vacuum valve was closed. Slowly add 180g of propylene oxide, and after the reaction is complete at 135-160°C, cool down to 80°C and discharge.

[0031] The second step: add 370g of the product obtained in the first step and 3.8g of solid KOH into the reactor, heat up to 90-110°C, vacuum dehydrate for 0.5-1.0h, then press 1500g of propylene oxide into the reactor, and control the feeding speed , keep the pressure of the reactor at 0.1-0.5MPa, keep the reaction temperature at 135-160°C, react until the pressure of the reactor no longer drops, cool down to normal...

Embodiment 1

[0033] Laurylamine polyoxypropylene ether obtained in Synthesis Example 1 is compounded with antioxidant, rust inhibitor, corrosion inhibitor and cosolvent, and the mass ratio of each component is: 65.0% laurylamine polyoxypropylene ether , 2.5% T502, 1.5% T747, 1.0% T551 and 30.0% aromatic oil.

[0034] The above-mentioned components are measured according to the ratio to be added, mixed and stirred evenly at room temperature until transparent, and the gasoline detergent of the present invention is obtained after filtration. The gasoline detergent of the present invention is added to commercially available 93# gasoline at a dose of 600 ppm. After evaluation by a professional department, the physical and chemical indicators of the oil product all meet the requirements of GB17930-2006. According to the GB / T19230.4 test method, the decrease rate of deposits generated by the automobile intake valve is simulated, and the change of the deposit increment of the combustion chamber of...

Embodiment 2

[0036] The cetylamine polyoxypropylene ether obtained in Synthesis Example 2 is compounded with antioxidant, rust inhibitor, corrosion inhibitor and cosolvent, and the mass ratio of each component is: 70.0% cetylamine 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 commercially available 93# gasoline at a dose of 700 ppm. After evaluation by a professional department, the physical and chemical indicators of the oil product all meet the requirements of GB17930-2006. According to the GB / T19230.4 test method, the decrease rate of the deposit generated by the automobile intake valve is simulated, and the change of the deposit increment of the combustion chamber of the automobile engine is simulated by a thermogravimetric analyzer. After testing, the sediment reduction rate of the ...

Abstract

The invention relates to a gasoline detergent prepared by using fatty amine polyoxypropylene ether expressed as a structural formula (I), wherein R is alkyl of C10 to C20; and p+d is a natural number of 12 to 31. The gasoline detergent prepared by using the fatty amine polyoxypropylene ether as a main component is used in gasoline and can obviously reduce the generation of sediments of a fuel air inlet system of a gasoline engine.

Description

technical field [0001] The invention relates to a gasoline detergent prepared with fatty amine polyoxypropylene ether, and also relates to a synthesis method of fatty amine polyoxypropylene ether. Background technique [0002] Fatty amine polyoxypropylene ether is a kind of polyether amine, which belongs to tertiary amine type polyether amine. It can be used in accelerated curing of epoxy resin, bonding, textile dyeing, ink and pigment dispersion, etc. Because the aliphatic amine polyoxypropylene ether has excellent surface activity and oil solubility, and is not easy to form deposits and gums at high temperatures, it can be used as the main component of automotive gasoline detergents. [0003] The detergent used in 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 automobile engines to the state of new cars as much as possible, so as to achieve relative reduction i...
