硫酸钾的萃取制备
Preparation of K2SO4 by Extraction
【摘要】 有机胺在强酸溶液中生成的铵离子,先于SO4-离子之前络合Cl-离子,因而胺可从KCl和H2SO4溶液中萃取出H+和Cl-离子,由此可得到K2SO4。采用分子量在250~600之间的叔胺和恰当的稀释剂做革取相,Cl-离子萃取率可达95%以上。
【Abstract】 In a solution of strong aicd,amine can form ammonium ion which can complex Cl- ion easier than SO2-4 ion,therefore amine can extract H+ ion and Cl- ion from the solution of KCl and H2SO4,K2SO4 is obtained. The extract phase is composed of dilution agent and tretamine with 250- 600 molecular weight, the extract efficency of Cl- ion is attained over 95 %.
