Phosphinous chloride, dimethyl- - Introduction
Dimethylchlorophosphine, the chemical formula is C2H6ClP, is an organic phosphorus compound. It is a colorless liquid with a pungent odor. Dimethylchlorophosphine can react with water vapor in the air to produce hydrogen chloride, a dangerous corrosive gas.
Dimethylchlorophosphine are widely used in organic synthesis. It can be used as a reagent, as a source of ligands in transition metal catalyzed reactions, and participate in the selective addition and oxidation of olefins. In addition, it can also be used in the preparation of catalysts and pyrotechnics for free radical reactions.
There are two main methods of preparing Dimethylchlorophosphine. One is obtained by reacting trimethylphosphine with a chlorine atom binding agent, and the other is obtained by reacting phosphorous chloride with a methylating agent. The preparation process requires attention to personal protective measures and operating conditions to avoid harmful gases and chemical reactions.
Due to the irritating and corrosive nature of Dimethylchlorophosphine, proper safety precautions must be taken when using them. Protective gloves, safety glasses and protective clothing should be worn to avoid contact with skin and eyes. Operate in a well-ventilated environment and away from flammable and explosive materials. In case of accidental exposure or inhalation, medical attention should be sought immediately.
