AI Technical Summary
Existing technologies for manufacturing carbonyl halides involve the use of large amounts of halogenated hydrocarbons, resulting in high environmental impact and low yields of halogenated hydrocarbons. Furthermore, the manufacturing process of phosgene presents safety hazards and high toxicity issues.
By irradiating a mixture of halomethane and oxygen with high-energy light in the presence of oxygen, and controlling the distance, time, and temperature between the light source and the gas, the efficient photodecomposition of halomethane to generate carbonyl halides is achieved, which are then used to react with alcohols and other compounds to generate target compounds.
This method improves the yield of halomethanes, reduces environmental impact, lowers safety risks, and enables the efficient and safe production of carbonyl halides and related compounds.
