A refractometric method is proposed for determining the concentration of aromatic diamines and their mixtures in amide-salt solvent. The kinetic curves of dissolution of aromatic amines were obtained and can be used to assess the relative importance of each factor of the dissolution process (dissolution temperature, stirrer speed, type of stirrer).
