Determination of organotrithiocarbonates with iodine and iodine halides in non-aqueous media.
The determination of organotrithiocarbonates with iodine and iodine halides in acetonitrile medium by visual and potentiometric method is described. The visual end-point is indicated by a sharp colour change from straw yellow to deep yellow caused by the first drop of oxidant solution in excess. Potentiometric titrations are performed with antimony or modified calomel reference electrodes and a bright platinum wire as an indicator electrode. The proposed method is simple, requires very little time because of the rapidity of the reaction, and the minimum of apparatus.
