Abstract

This invention relates to a method for preparing acetyl chloride by reacting 1,1-dichloroethane with chlorine and oxygen under the irradiation of light.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A method for the preparation of acetyl chloride characterized by interacting 1,1-dichloroethane and chlorine gas and oxygen gas under light irradiated conditions. 
     
     
       2. A method according to claim 1, wherein oxygen gas and chlorine gas are fed in a ratio within a range of 5:1 - 1:5. 
     
     
       3. A method according to claim 1, wherein the reaction is conducted with the use of light having a wavelength smaller than 5000 A. 
     
     
       4. A method according to claim 3, wherein said wavelength is within a range of 2000 - 4500 A. 
     
     
       5. A method according to claim 1, wherein the reaction is conducted at a temperature of from room temperature to 200° C. 
     
     
       6. A method according to claim 5, wherein said temperature is within a range of 20° - 100° C.
