Question

Limited per-pass conversion, does not causes any technical problem in reactor.

(a) True

(b) False

The question was posed to me during an interview.

My doubt is from Types of Reductions topic in section Amination by Reduction of Unit Processes

Answer 1

Correct option is (b) False

To elaborate: Vapour-phase reductions are sometimes fraught with a number of technological problems: (1) limited per-pass conversion, thus necessitating separation of aniline from nitrobenzene and (2)sensitivity of catalytic operations which may result in over reduction and relatively low yields of amine compared with competitive processes, particularly Bechamp reductions.
