Question

Write the chemical equation of manufacture of chlorine by Deacon’s process and also write chemical equation of the reaction of Cl$_2$ with sulphur.

Hint:

Always mention the catalyst (CuCl$_2$) and temperature in Deacon’s process, as it is crucial for industrial application.

Answer 1

Step 1: Deacon’s process.
In Deacon’s process, chlorine is manufactured by the oxidation of hydrogen chloride gas using oxygen in the presence of a catalyst (CuCl$_2$).
\[ 4HCl + O_2 \xrightarrow{CuCl_2, 723K} 2Cl_2 + 2H_2O \] Step 2: Reaction of chlorine with sulphur.
When chlorine reacts with sulphur, sulphur dichloride is formed.
\[ S + Cl_2 \rightarrow SCl_2 \] Conclusion:
- Deacon’s process is an industrial method for preparing chlorine.
- Chlorine reacts with sulphur to give sulphur dichloride (SCl$_2$).
