Abstract
p-Nitrophenetol is prepared by heating an aqueous alcoholic solution of p-nitrochlorbenzene of low concentration with a quantity of an alkaline reagent, such as sodium ethoxide, not substantially in excess of that chemically equivalent to the chloro-derivative, at or above the normal boiling-point of the aqueous alcohol and without ebullition. For concentrations of the chloro-derivative of 3 per cent and upwards, less than the equivalent of the alkali may be used. According to examples, concentrations of 3 and 5 per cent of p-nitrochlorbenzene in 85 per cent alcohol are heated with sodium ethoxide and caustic soda respectively in an autoclave at temperatures of 90-120 DEG C. To prevent reduction to azoxy-compounds the autoclave is lined with enamel, silver or nickel.
