    • PROBLEM TO BE SOLVED: To provide a method for producing a 4-nitrosodiphenylamine in good operability, with which excellent selectivity is maintained, agglomeration of a 4-nitrosodiphenylamine is controlled and fine particles are obtained in good dispersibility so that adhesion of the agglomerated material to a reactor wall and a stirring shaft is prevented.
      SOLUTION: The method for producing a 4-nitrosodiphenylamine comprises reacting a diphenylamine with a nitrosating agent and hydrogen chloride in the presence of a surfactant in a solvent. In the method, a nitrosating agent selected from nitrosyl chloride, a nitrite, an alkyl nitrite and a nitrogen oxide is preferable as the nitrosating agent and a nonionic surfactant or an anionic surfactant is preferable as the surfactant.

    • PROBLEM TO BE SOLVED: To provide a method for producing a chloronitroso compound from a compound selected from an alkene and a cycloalkene in good operability and economically advantageously.
      SOLUTION: The method for producing a chloronitroso compound comprises mixing a mixture containing a compound selected from an alkene and a cycloalkene, a nitrite and water with hydrogen chloride at -4 to 20°C. In this method, hydrochloric acid is preferably used as hydrogen chloride and a 5-6C compound, more preferably 2-methyl-2-butene or 2,3-dimethyl-2-butene is used as the compound selected from an alkene and a cycloalkene.
