| Abstract: | In this paper,a new process of production of non-chlorite potassium fertilizer potassium sulfate has been studied by solvent extraction method under normal temperature and pressure .The result show:in this studied system triethanolamine is taken as organic solvent,and n-Butyl alcohol as diluent,when the triethanolamine's concentration is 50%,and the molar ratio of ammonium sulfate topotassium chlorate is 1.1:2.0 and 3:1 for the liqueurs phase to solid,and 1.5~2 hour for reaction time and 20~25 for reaction temperature, the conversion ratio will be up to the optical value. |
