摘　　要：以氯化钾、硫酸、氨为原料 ,在常温下采用缔合置换法合成无氯钾肥 ,在试验范围内找出适宜的工艺条件 ,同时测定了该产品的主要物性 .The way of associating-displacing at normal temperature was researched to produce a kind of non-chlorine potass-fertilizer KNH 4SO 4 with KCL, H 2SO 4 and NH 3. The most feasible technologic conditions were obtained in the range of the study and the main physical characters of K(NH 4)SO 4 were measured.
