According to a novel process, triazolinethione derivatives of the formulain whichR1 and R2 are each as defined in the description can be prepared by reacting triazole derivatives of the formula with sulphur in the presence of an aprotic polar diluent at temperatures between 140° C. and 160° C.,where the amounts of the reaction components are chosen such that between 6 and 15 mol of sulphur are present per mole of triazole derivative of the formula (II),and where air is passed over the reaction mixture during the reaction.
