Abstract: The invention relates to a process for the production of nitroaryl compounds which are at least monosubstituted, by nitration of aryl compounds which are at least monosubstituted, which process comprises carrying out the nitration in a two-phase system which consists of an inorganic phase consisting of sulfuric acid having a concentration of at least 80% and an organic phase consisting of an inert organic liquid in which the nitration product is almost insoluble in the presence of sulfuric acid, at a temperature in the range from -30.degree. to 100.degree. C., with nitric acid as nitrating agent.The novel process can be generally employed for aryl compounds which are at least monosubstituted. The corresponding nitroaryl compounds are obtained in high yield and isomeric purity.

Abstract: A process for the production of 4-acylamido-2-nitro-1-alkoxybenzenes by acylating p-alkoxyaniline with an acylating agent to 4-acylamido-alkoxybenzenes and subsequently nitrating these latter to 4-acylamido-2-nitro-1-alkoxybenzenes, which process comprises carrying out the reaction in an inert solvent, without isolation of the intermediates, using 88 to 95% sulfuric acid in the weight ratio of 6:1 to 10:1, based on the p-alkoxyaniline employed, during the nitration step.
