Title: Improvements in or relating to the preparation of m-chloroaniline
Inventor: LATOURETTE HAROLD KENNETH
Filed: 1959-05-21
Abstract: A process for preparing substantially pure m-chloroaniline from crude m-chloronitrobenzene containing a substantial amount of isomeric impurity comprises heating a solution of an alkali metal hydrosulphide with the crude mixture until the reaction is substantially complete and recovering substantially pure m-chloroaniline from the reaction mixture.  The reduction is preferably carried out by adding the chloronitrobenzene to a 20% aqueous solution of sodium hydrosulphide at a temperature between 80 DEG C. and the reflux temperature using a mole ratio of hydrosulphide to chloronitrobenzene of 3.2:2.  The hydrosulphide reduces the meta isomer to m-chloroaniline but converts the ortho and para isomers to thiophenols, sulphides and disulphides from which the m-chloroaniline may easily be removed by reduced pressure distillation.  The examples describe the reduction of m-chloronitrobenzene which may contain as impurity o- and p-chloronitrobenzene, nitrobenzene and 2,5-dichloronitrobenzene.
