摘要
针对氨溶液中磷石膏制备硫酸钾工艺存在的问题 ,考察了甲醇、氨 甲醇等溶剂对反应过程氧化钾收率的影响 ,筛选出氨 异丙醇作为适宜的添加溶剂 ,并对氨
To improve the process of potassium sulphate prepared from phosphogypsum in ammonia solution,the influence of solvent such as methanol,methanol-ammonia on the yield of potassium oxide was studied.The result reveals that the system of 2-propanol and ammonia is optimal.Meanwhile,the process of potassium sulphate prepared from phosphogypsum in the system of 2-propanol and ammonia was also investigated.
