Usage

General Description

1,2-Dichlorotrifluoroethyl trifluoromethyl ether, also known as Halon 3611, is a chemical compound primarily used as a fire-extinguishing agent. It is a clear, colorless liquid that is highly volatile and non-flammable, making it an effective choice for suppressing fires in enclosed spaces. 1,2-DICHLOROTRIFLUOROETHYL TRIFLUOROMETHYL ETHER is a member of the halogenated ethers family and is known for its excellent fire-fighting capabilities and relatively low toxicity. It is commonly used in applications where traditional water-based fire suppression methods may not be practical, such as in computer server rooms, aircraft, and in some industrial settings. However, due to environmental concerns and its potential to contribute to ozone depletion, the use of 1,2-Dichlorotrifluoroethyl trifluoromethyl ether has been largely phased out in favor of more environmentally-friendly fire suppression alternatives.

Method for preparing fluorine-containing halogenated ether

The invention relates to a method for preparing fluorine-containing halogenated ether, belonging to the technical field of organofluorine chemistry. The method comprises the following steps: using fluorooxytrifluoromethane and halogenated alkene as raw materials and continuously feeding gas phase halogenated alkene and gas phase fluorooxytrifluoromethane into a reactor to undergo thermal addition reaction to obtain fluorine-containing halogenated ether; controlling the spray pressure of fluorooxytrifluoromethane to be 0.1-1MPa, the reaction temperature to be 80-200 DEG C and the mole ratio of fluorooxytrifluoromethane to halogenated alkene to be (0.6-1.3) to 1. The method has the beneficial technical effects that the two raw materials are in gas phase; continuous obtainment of fluorine-containing halogenated ether with high yield and efficiency can be ensured by controlling the specific spray pressure of fluorooxytrifluoromethane, the specific reaction temperature and the specific reaction raw material ratio; the method only adopts two kinds of reaction raw materials, is simple in process, can be used for continuous production, has the advantages of low metering requirements, convenience in operation and high yield and efficiency and is very suitable for industrial production.
