| titleOfInvention | Process for producing 4,4'-dichlorodiphenyl sulfoxide |
| abstract | The invention relates to a process for producing 4,4'-dichlorodiphenyl sulfoxide comprising: (a) reacting thionyl chloride, chlorobenzene and aluminum chloride in a molar ratio of thionyl chloride : chlorobenzene : aluminum chloride of 1 : (6 to 9) : (1 to 1.5) at a temperature in the range from 0 to below 20°C, forming an intermediate reaction product and hydrogen chloride, (b) mixing aqueous hydrochloric acid and the intermediate reaction product at a temperature in the range from 70 to 110°C to obtain a crude reaction product comprising 4,4'-dichlorodiphenyl sulfoxide, (c) separating the crude reaction product into an organic phase comprising the 4,4'-dichlorodiphenyl sulfoxide and an aqueous phase, (d) washing the organic phase with an extraction liquid. |
