摘要
介绍了利用废弃磷石膏制备硫酸钾的新工艺,研究了反应过程和再结晶过程的基本条件,并介绍了工业规模生产的初步方案。
This paper describes the new chemical process about producing potassium sulphate employing waste phosphoric gypsum directly, which is catalysed by a liquid medium. It discusses the optimum conditions of the reaction process. A basical plan with industrial scale is therfore introduced.
