To achieve optimum yield in synthesis of HCN, oxygen should be in excess.(a) True(b) FalseThis question was addressed to me in a national level competition.This is a very interesting question from Technical Manufacturing of Amino Compound in portion Amination by Ammonolysis of Unit Processes

Answer»

Correct choice is (b) False

The EXPLANATION is: In order to obtain optimum yields, it is necessary to use less OXYGEN (as AIR) than the amount shown in the above equation, to prevent EXCESSIVE oxidation of AMMONIA to nitrogen oxides and methane to carbon oxides.
