Determination of certain unsaturated hydrocarbons by titration with permanganate in non-aqueous medium.
Ion-association complexes of permanganate with tetrabutylammonium can be dissolved in chloro- or bromobenzene and used for photometric titration of certain unsaturated hydrocarbons at 45-50 degrees . MnO(2) is precipitated and must be filtered off before the absorbance is measured.
