Problems solved by technology

[0004] At present, the existing aliphatic alcohol gasoline consumes a lot, storage and transportation are stratified, it is difficult to cold start at low temperature, it has air resistance at high temperature, it has corrosion to metal, it has problems such as dissolution or swelling to non-metal, and low anti-knock performance. Therefore, this property The product is difficult to promote, waiting for the birth of gasoline detergent

Embodiment 1

[0048] Prepare the following raw materials: 83 kilograms of methanol; 11 kilograms of ethyl formate; 3 kilograms of light solvent oil; 3 kilograms of dimethyl carbonate of the reagent product, the total weight of the above-mentioned basic components is 100 kilograms, and then prepare 0.1 kilogram of ethanolamine; Benzoyl 0.1 kg; T-746 rust inhibitor 0.0003 kg. The ambient temperature of the preparation is -31°C±1°C. Use a mixing kettle, start the mixing kettle, and add methanol, ethyl formate, light solvent oil, dimethyl carbonate, T-746 rust inhibitor, Benzoyl peroxide and ethanolamine were stirred and mixed for 30 minutes, and the pH value was adjusted to 6.0 with aliphatic nitrogen-containing compounds and / or acetic acid. After the mixing was completed, a mixed solution was obtained, and the mixed solution was left to stand for 24 hours to obtain a finished gasoline detergent. The finished product is mixed with gasoline at a ratio of 48:52.

Embodiment 2

[0050] Prepare the following raw materials: 91 kilograms of ethanol; 7 kilograms of propyl formate; 1 kilogram of No. 200 solvent oil; 1 kilogram of dimethyl carbonate of industrial grade, the total weight of the above-mentioned basic components is 100 kilograms, and then prepare 1 kilogram of diethanolamine; Dibenzoyl oxide 1 kg; T-747A rust inhibitor 0.1 kg. The ambient temperature of the preparation is 44°C±1°C, use a mixing tank, start the mixing tank, and add ethanol, propyl formate, No. 200 solvent oil, dimethyl carbonate, T-747A rust inhibitor, Oxidize dibenzoyl and diethanolamine and stir and mix for 45 minutes, adjust the pH value to 7.5 with aliphatic nitrogen-containing compounds and / or acetic acid, obtain a mixed solution after the mixing is completed, and stand the mixed solution for 8 hours to obtain the finished product of gasoline detergent. The finished product is blended with gasoline at a ratio of 29:71.

Embodiment 3

[0052] Prepare the following raw materials: 87 kg of propanol; 9 kg of isopropyl formate; 2 kg of No. 1000 solvent oil; 2 kg of commercially available dimethyl carbonate, the total weight of the above basic components is 100 kg, and then prepare 0.5 kg of triethanolamine ; 0.5 kg of dicarbonyl dicyclohexyl peroxide; 0.05 kg of LB-748 rust inhibitor. The ambient temperature of the preparation is 5°C±1°C. Use a mixing kettle, start the mixing kettle, and add propanol, isopropyl formate, No. 1000 solvent oil, dimethyl carbonate, and LB-748 rust inhibitor in sequence under continuous stirring , dicarbonyl peroxide, and triethanolamine were stirred and mixed for 38 minutes, and the pH value was adjusted to 6.5 with aliphatic nitrogen-containing compounds and / or acetic acid. After the mixing was completed, the mixed solution was obtained, and the mixed solution was left to stand for 17 hours to obtain gasoline clean The finished product of the agent, the finished product is mixed wi...

Abstract

The invention provides a gasoline detergent. The gasoline detergent is prepared from aliphatic alcohols, aliphatic carboxylates, solvent oil, dimethyl carbonate, aliphatic nitrogen-containing compounds, peroxides and anti-corrosion and anti-dissolution compounds. The gasoline detergent can supply enough oxygen and enough micro detonating agents; synchronous full combustion of gasoline and the gasoline detergent is accelerated; the combustion is stable; the heating value is high; the generation of poisonous and harmful gas is reduced; components of tail gas are changed; the detergency of the gasoline is improved; the environment friendliness is improved; original deposited carbon is effectively removed; when the gasoline is continuously used, the deposited carbon is not generated; is effectively saved, and the pollution of automobile tail gas to the air is effectively reduced, so that the blue sky is protected; acid rain and haze are reduced; green mountains and rivers are indirectly protected; the gasoline detergent has the effects of saving energy, protecting environment and reducing emission, also has good environmental protection benefits and social benefits, and is used as green new energy which is urgently needed by people.

Description

technical field [0001] The invention discloses a gasoline detergent and a preparation method thereof. Background technique [0002] As we all know, energy environmental protection, energy saving and emission reduction are the most important issues in the world today, affecting the national economy, the people's livelihood and the survival of future generations. etc. During the combustion process, a certain amount of harmful gas is produced. Seriously affect the quality of the environment. On the other hand, the shortage of traditional coal and oil series also needs to be solved urgently. [0003] In view of this situation, it is of great significance to make full use of various renewable resources and research and develop gasoline detergents to replace some petroleum fuels. [0004] At present, the existing aliphatic alcohol gasoline consumes a lot, storage and transportation are stratified, it is difficult to cold start at low temperature, it has air resistance at high te...
