Hydrolysis of ferric chloride in solution
A process has been developed that recovers the chloride ions as HCl and either minimizes the volume of radioactive waste or permits recycling of the radioactive chlorides. The process involves a two-step hydrolysis at atmospheric pressure, or preferably under a slight vacuum, and relatively low temperature, about 200{degrees}C.

VINYL CHLORIDE PRODUCTION-SUMMARY
oxychlorination called the balanced process. Direct chlorination by itself is a process that operates at lower temperatures and produces fewer by products when compared to oxychlorination. Oxychlorination is used in vinyl chloride production because it consumes the hydrochloric acid (HCl) generated by 1,2 dichloroethane (EDC) pyrolysis.

Process for the preparation of ferric chloride.
The conventional process for manufacturing ferric chloride in solution firstly involves attacking iron with HCl leading to the formation of ferrous chloride: Fe + 2HCI => FeCI 2 + H 2. Then, the ferrous chloride thus obtained is converted into ferric chloride by chlorination: FeCI 2 + 1 / 2CI 2 => FeCI 3.
