Introduction
3,5-Difluorobromobenzene is an organic compound. The following is an introduction to the properties, uses, preparation methods and safety information of 3,5-difluorobromobenzene:Properties: 3,5-Difluorobromobenzene is a colorless liquid with a strong burning odor. It is soluble in organic solvents such as ethanol, methylene chloride, and ethers.Uses: 3,5-Difluorobromobenzene has a wide range of uses in the chemical industry. It can also be used in the production of dyes and in rubber processing.Preparation method: The preparation of 3,5-difluorobromobenzene can be obtained by brominating benzene to phenyl bromide, and then reacting with hydrogen fluoride to obtain 3,5-difluorobromobenzene. Among them, benzene bromination process can be used cuprous bromide or dibromide oxide as brominating agent, and the bromination reaction is carried out at room temperature. Hydrogen fluoride is heated to an appropriate temperature and then reacted with phenyl bromide.Safety information: 3,5-Difluorobromobenzene should be used or handled with caution. It is irritating and corrosive to the eyes, skin, and respiratory tract. Rinse with plenty of water immediately after contact. A full-face mask, protective gloves and protective eyewear should be worn when in use. 3,5-Difluorobromobenzene is also flammable and should be kept away from fire sources and high temperature environments, and should be stored in a cool, dry and well-ventilated place.
