Question

What is the catalyst used in Manufacturing of aniline?

(a) Zinc

(b) Copper carbonate

(c) Iron

(d) None of the mentioned

This question was posed to me by my college professor while I was bunking the class.

The doubt is from Types of Reductions in chapter Amination by Reduction of Unit Processes

Answer 1

The correct option is (b) Copper carbonate

The explanation is: The reaction is carried out at very slight pressure (about 5 psig) over a reduced copper carbonate catalyst at temperatures ranging from about 200°C at the entrance to the catalytic reactor to 350°C at the exit.
