Question

Which catalyst is used in conversion of chlorobenzene to phenol by Rasching process?

• A. Calcium phosphate
• B. Calcium carbonate
• C. Calcium sulphate
• D. Calcium chloride

Hint:

Remember: Rasching process converts chlorobenzene to phenol using steam and calcium phosphate as catalyst.

Answer 1

The Correct Option is A

Step 1: Recall the Rasching process.
The Rasching process is an industrial method used to convert chlorobenzene into phenol using steam at high temperature and pressure.
Step 2: Identify the catalyst used.
Calcium phosphate acts as a catalyst in this process and facilitates the hydrolysis of chlorobenzene to phenol.
Step 3: Eliminate incorrect options.
Calcium carbonate, calcium sulphate, and calcium chloride are not used as catalysts in the Rasching process.
Step 4: Conclusion.
Hence, the catalyst used in the Rasching process is calcium phosphate.
