Abstract
A simple, rapid and selective titrimetric procedure for the determination of 0.1–20 mg of aryldialkylamine has been developed. The method is based on the reduction of the aryldialkylamine oxides with iodide in acidic medium. The rate of reaction is accelerated by heating the reactants just to boiling, and after cooling the reaction products, the liberated iodine is titrated with thiosulphate solution, with starch as indicator. The method can be applied successfully to the determination of aryldialkylamine oxides in the presence of aliphatic and aromatic amine oxides and amines.
