Abstract

In the current study, the physicochemical properties of N-benzoyl-N'-(2-naphthylsulfonil)hydrazine (BNSH) were measured by spectrophotometric and gravimetric methods. The solubility of this reagent was determined in ethanol, KOH (0.1 mol/L), toluene, chloroform, and hexane solutions. It was shown that BNSH can be used in the processes of flotation and extraction. Results of spectrophotometry confirmed that BNSH is a weak diacid due to obtained values of the acid dissociation constants (pKa1= 7,78 ± 0,42; pKa2 = 13,53 ± 0,44). Also, it was established that BNSH solutions are sufficiently stable over time in alkaline media: the degree of hydrolysis within two hours is 8,10%. The results of stalagmometric method showed that BNSH is a surfactant.
