Question

In which process low cost acrylonitrile is produced?

(a) Arc process

(b) Electro organic chemical process

(c) Electrorefining

(d) Electrowinning

This question was addressed to me in homework.

This is a very interesting question from Inorganic Chemical topic in chapter Inorganic Chemical Industries of Chemical Technology

Answer 1

The correct choice is (b) Electro organic chemical process

To explain: Electro organic chemical process uses low-cost acrylonitrile made in one step from propylene, ammonia and air to give adiponitrile in a second step. Alternatively, one must go in four steps from benzene to cyclohexane to adipic acid to adiponitrile.
