There is difference of opinion as to the course of the reaction, but many chemists hold that the ferrous salt in solution is converted into a basic salt at the expense of 1 D. R. P. 172569. HYDROGEN ATION 93 the oxygen of the nitro-compound, which undergoes reduc- tion, and that the basic salt in turn reacts with the iron in such a way that ferrous chloride is regenerated : 2 4 FeQ 2 + 4 C 6 H 5 -N0 2 + 4 H 2 = i2Fe 2 C! 4 O + 4 C 6 H 5 NH 2 . I2Fe 2 Q 4 O + QFe Another explanation of the react...ion is that the ferrous chloride produced acts as a carrier, and the reduction proceeds through the action of iron and water : C 6 H 5 -N0 2 + 2Fe + 6HC1 = C 6 H 5 'NH 2 + 2FeQ 3 + 2H 2 O. C 6 H 5 -N0 2 + 2Fe + 4 H 2 _ C 6 H 5 'NH 2 + 2 Fe(OH) 3 . The velocity of the reaction depends upon the quantity of ferrous chloride present, and also varies with the amount of acid in the solution. Reduction with Hydrosulphites and Formaldehyde Sulphoxylates. In discharging a number of dyes employed in pattern printing on textile fabrics, the addition of a catalyst to the reducing agent has been found to increase its efficiency in a very marked manner.
