Title: Production of nitrophenetoles
IPC: C07C205/37
Filed: 1959-05-15
Abstract: Nitrophenetoles are prepared by heating together a nitrochlorobenzene, a caustic alkali and ethanol in the presence of a solvent comprising ethanol, discontinuing the reaction after substantial but less than the maximum possible conversion to the corresponding nitrophenetole has taken place, subjecting the resultant mixture of nitrochlorobenzene and the corresponding nitrophenetole to distillation under reduced pressure so as to separate a fraction containing substantially all the unchanged nitrochlorobenzene together with some nitrophenetole and recycling the fraction to a subsequent conversion step.  The reaction is preferably carried out using caustic soda and 95% aqueous ethanol to an 85% conversion and then distilling the mixture at 180-200 DEG C. at 20-60 mms. pressure.  The examples describe the preparation of the para and ortho isomers.
