| Abstract: | The method of making potassium sulfate was compared by potassium carbonate and by sulfate-ammonium.The best technology conditions were obtained as follows:stirring speed 1.5 m/s,stirring time 30 min,pulp concentration 20 g/100 mL and the temperature of water bath 80 ℃.The best conditions from(NH4)2SO4 were as follows:the molar ratio of(NH4)2SO4 ∶KCl 1.1 ∶1,stirring speed 2.0 m/s,stirring time 80 min,pulp concentration 25 g and the concentration of ethanol 40%. |
