Investigations have shown that a compound with a thioamide group from the thioacylanilide class, of the following structure, is an effective flotation reagent. With the aim of using this reagent in ore flotation, the authors studied the conditions of its synthesis and some of its physicochemical properties. The method based on the reaction of acylanilides with tetraphosphorus decasulfide is the most suitable for industrial operation. Experimental data show that by the use of a small excess of acylanilide it is possible to obtain a high yield of a product having the required viscosity and to dispense with solvents. The physicochemical properties of the reagent have been investigated.
