- Abstract
The oxidation of aniline hydrochloride by ammonium peroxydisulfate in non-aqueous media was studied, when the monomer or oxidant or both were not completely soluble. Polyaniline was formed in acetone, methanol and toluene. Aniline oligomers only were produced in chloroform and n-butylacetate. No interaction of the monomer and the oxidant was observed in dimethylsulfoxide and N-methylpyrrolidone. UV-visible and Fourier transform infrared spectra were recorded in order to study the molecular structure of the final products. Conductivity was measured for conducting protonated forms and corresponding bases. An explanation of aniline hydrochloride oxidation in various organic media is offered. Copyright © 2011 Society of Chemical Industry We report the oxidation of aniline hydrochloride in various organic solvents-protic, aprotic, polar, non-polar-in which the reactant (aniline hydrochloride) and oxidant (ammonium peroxydisulfate) are not completely soluble. Polyaniline prepared in the classic way in aqueous media always contains water which is difficult to remove by drying. The preparation of polyaniline in non-aqueous media may therefore become important when the presence of water has to be avoided in subsequent applications such as in electrochemistry or catalysis. The washing of samples with water would be skipped in such cases.
