Embodiment 1-4

[0047] According to the ratio of raw materials in Table 1 and according to the following method to prepare fuel-saving gasoline detergent containing friction modifier.

[0048] (1) Add carrier oil, diluent, detergent, and dispersant to the reaction kettle in sequence and heat to 55°C while stirring, and stir for 0.5h to mix evenly;

[0049] (2) Add friction modifier, antioxidant, rust inhibitor, demulsifier, keep warm and stir for 0.5h to mix evenly;

[0050] (3) Cool down to 40°C, add an octane number improver, stir for 1 hour, filter through a 5 μm filter, and release to obtain the product.

[0051] Table 1: Raw material ratio table of embodiment 1-4

[0052]

Embodiment 5

[0054]Raw material (mass percentage) of fuel-saving gasoline detergent containing friction modifier: 40% of Mannich base, 7% of borated polyisobutylene succinimide, 8% of ethyl tert-butyl ether, N,N-di( 12) Molybdenum alkyl dithiocarbamate 4.5%, antioxidant 0.4%, dodecenyl succinic acid 2.2%, simethicone 0.1%, dimethyl carbonate 15%, the balance is azelaic acid Bis(2-ethylhexyl) ester.

[0055] The antioxidant is obtained by uniformly stirring and mixing 50 wt% of 4,4'-dioctyl dianiline and 50 wt% of 4,4'-dimethyl dianiline.

[0056] Preparation of fuel-saving gasoline detergent containing friction modifier:

[0057] (1) Add bis(2-ethylhexyl) azelate, dimethyl carbonate, Mannich base, and borated polyisobutylene succinimide in turn to the reaction mixing kettle and heat to 55°C, 400 rpm Stir for 0.5h to mix evenly;

[0058] (2) Add molybdenum N,N-di(dodecyl)alkyldithiocarbamate, antioxidant, dodecenylsuccinic acid, and simethicone, at a temperature of 55°C, and stir at 400 ...

Embodiment 6

[0061] A fuel-saving gasoline detergent containing a friction modifier was prepared according to the method of Example 5, except that the antioxidant was only 4,4'-dioctyldiphenylamine. The fuel-saving gasoline detergent containing the friction modifier of Example 6 was obtained.

Abstract

The invention discloses a gasoline cleansing agent containing friction modifier and capable of saving fuel oil and a preparation method of the gasoline cleansing agent. The gasoline cleansing agent containing friction modifier and capable of saving fuel oil is composed of, by mass, 20-70% of a clearing agent body, 5-15 parts of a dispersing agent, 5-15% of octane enhancer, 2.5-7.5% of the friction modifier, 0.1-0.8% of antioxygen, 0.1-4.5% of an antirust agent, 0.01-1% of demulsifier, 10-50% of diluents and the balance carrier oil.

Description

technical field [0001] The invention relates to a fuel additive, in particular to a fuel-saving gasoline detergent containing a friction modifier and a preparation method thereof. Background technique [0002] Gasoline additives are functional substances added to gasoline in order to make up for the defects in some properties of gasoline and to give gasoline some new and excellent properties. It is composed of various organic molecules, anti-oxidation, anti-corrosion and other materials. Power, remove carbon deposits, clean oil circuit, save fuel, anti-rust and other functions. [0003] When the car engine is running, the temperature of the fuel injector is around 100°C, and the temperature of the intake valve is between 200-300°C. At such a temperature, the unstable components in gasoline are prone to oxidative condensation reactions, forming colloids and carbon deposits, which are deposited on the fuel injectors, intake valves, and the walls of the combustion chamber at t...
