Problems solved by technology

And the research mainly focuses on its research on preventing the precipitation of ice crystals. However, the shortcoming of current anti-icing agents is that the flash point is low. The flash point of general jet fuel (about 45 ° C ~ 49 ° C), which limits its application in the field of military jet fuel

preparation Embodiment 1

[0042] At room temperature, introduce nitrogen gas into a 500L stirred tank for about 20 minutes to remove the air in the reactor, then add 100 kg of diethylene glycol methyl ether, and then add 1 kg of antioxidant 2,6 di-tert-butyl p-cresol under stirring, Continue to stir for 15 minutes. After the mixture is evenly stirred, add 0.015 kg of preservative benzotriazole and 0.01 kg of refined naphthenic acid (T1601) as antiwear agent. Stirring was continued for about 30 minutes to obtain the final anti-icing agent composition.

preparation Embodiment 2 to 24

[0044] Obtain the anti-icing agent composition in Preparation Example 2 to 24 according to the same method of Preparation Example 1, and the components of the anti-icing agent composition in Preparation Examples 2 to 24 are shown in Table 1 below:

Abstract

The invention relates to a deicing composition for military jet fuel. The deicing composition for military jet fuel comprises diethylene glycol monomethyl ether, an antioxidant, a corrosion remover and an antiwear agent. The deicing composition for military jet fuel has a high flash point and is particularly suitable for the military jet fuel.

Description

technical field [0001] The invention relates to an anti-icing agent composition for jet fuel, specifically, the anti-icing agent composition has a high flash point and is especially suitable for military jet fuel. Background technique [0002] Jet fuel, also known as aviation kerosene, is divided into military jet fuel and civilian jet fuel in foreign countries. In my country, it was originally a common jet fuel for military and civilian use. The latest revision of GB6537-2006 "No. 3 Jet Fuel" also divides it into military jet fuel and civil jet fuel. fuel. Moisture in jet fuel is easy to form ice crystals at low temperatures, and in severe cases, it will block the oil filter system of the engine and cause safety accidents. The basic way to prevent the formation of ice crystals is to add anti-icing agents. Anti-icing agent has both lipophilicity and hydrophilicity. It is a chemical substance soluble in both oil and water. It can not only prevent the crystallization of water ...
