Method of preparing 2,2'-dithiodianiline by the steps of (A) obtaining an agitated mixture of a water solution of a salt of o-aminothiophenol and an unstable dispersion therein of a liquid hydrocarbon, (B) oxidizing said salt by the slow addition of a water soluble peroxide, (C) discontinuing the agitation to allow the formation of a sharply defined lower aqueous phase and upper hydrocarbon phase, (D) drawing off said lower aqueous phase and (E) distilling the hydrocarbon phase therefrom and recovering said 2,2'-dithiodianiline as a distilland
