Introduction
O-chlorobenzoyl chloride. Here are some important properties and information about this compound:
Properties: O-chlorobenzoyl chloride is a colorless liquid with a pungent odor. It is highly corrosive and reacts with water to form hydrogen chloride gas. It has high volatility and is easily soluble in organic solvents such as ethanol, ether and benzene.
Uses: O-chlorobenzoyl chloride is an important intermediate in organic synthesis. For example, it can be used to synthesize pesticides-like compounds such as o-chlorophenol and o-chlorophonool, as well as in the synthesis of dyes and phosphates.
Preparation method: The preparation method of o-chlorobenzoyl chloride is generally made by reacting benzoyl chloride with aluminum chloride at room temperature. The specific steps are to suspend benzoyl chloride in anhydrous ether, then slowly add aluminum chloride and stir fully, and after the reaction is completed, the target product is obtained by distillation and purification.
Safety Information: O-chlorobenzoyl chloride is an irritating and corrosive compound and should be handled with care. Appropriate protective equipment such as chemical protective gloves, goggles, and protective clothing must be worn when in use. Avoid contact with skin and eyes, and avoid inhaling its vapors. A well-ventilated environment must be maintained during use or storage.
