chlorodi-p-tolylphosphane - Introduction
Di-p-tolylphosphine chloride is an organophosphorus compound with the chemical formula C6H5CH2PCl2. It is a colorless to pale yellow liquid with a pungent odor at room temperature.
Di-p-tolylphosphine chloride has good solubility and is soluble in organic solvents such as ether, chloroform and dichloromethane. It has a melting point of about -10°C and a boiling point of about 192°C. The compound has high reactivity and can react with various electrophiles (such as aldehydes and ketones), nucleophiles (such as amines) and aromatic compounds. Di-p-tolylphosphine chloride can also be used as an esterifying agent, an oxidizing agent, a flame retardant, and the like.
A common method for preparing di-p-tolyl phosphine chloride is by reacting p-tolyl phosphorochloridate with dichloromethane, followed by distillation to obtain the product. During the preparation process, care should be taken to use appropriate protective measures, such as wearing chemical protective gloves, goggles and protective clothing, to avoid contact with skin, eyes and respiratory tract.
When using di-p-tolylphosphine chloride, you should follow safe operating procedures and store it in a closed container, away from fire and heat sources. Due to its high reactivity and irritation, it is necessary to avoid contact with flammable substances and strong oxidants, and to avoid inhalation of its vapors. At the same time, when disposing of waste, it should comply with local regulations to ensure environmental safety.
