Studies on the Optimisation of the Preparation Method and the Characterisation of Zinc Butyl Xanthate

Zinc butyl xanthate (Zn(bxt) 2 ) was prepared using both AR-grade and commercial-grade n-butyl alcohol (n-BuOH), potassium hydroxide (KOH), carbon disulphide (CS 2 ), and zinc chloride (ZnCl 2 ). The effect of the order of mixing of the reactants on the reaction time and the yield of Zn(bxt) 2 was s...

Description
Summary:Zinc butyl xanthate (Zn(bxt) 2 ) was prepared using both AR-grade and commercial-grade n-butyl alcohol (n-BuOH), potassium hydroxide (KOH), carbon disulphide (CS 2 ), and zinc chloride (ZnCl 2 ). The effect of the order of mixing of the reactants on the reaction time and the yield of Zn(bxt) 2 was studied. The effect of the amount of ZnCl 2 used for precipitation on the yield of Zn(bxt) 2 was also investigated. The irritating smell of Zn(bxt) 2 could be reduced considerably by using commercial-grade reagents. The yield of Zn(bxt) 2 could be increased and the reaction time reduced. The maximum yield was obtained when 1 mol% ZnCl 2 was used. The Zn(bxt) 2 obtained was characterised by means of Fourier transform IR spectroscopy (FTIR), thermogravimetric analysis (TGA), differential thermal analysis (DTA), and proton magnetic resonance ( 1 H NMR) spectroscopy.
