    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.

  • Patent number: 4243653
    Abstract: Non-ionic polyiodo saccharidic ether substituted anilines are provided as contrast media, the ether being non-glycosidyl. The compounds have excellent physical properties in having acceptable water solubility or capable of stable suspension, relatively low osmotic pressure, good thermal stability, so as to be heat sterilizable, and a high iodine proportion. The compounds can be prepared from polynitroaromatics by substitution and reduction.
