硫酸氢钾制备

1.将87g K2SO4与27mL浓H2SO4(相对密度1.84)置于铂皿中混合，小心加热，直至反应物变得完全透明。将反应物的熔融体倒入置于冷水中冷却的瓷制或铂制的容器中，物料固化后，将其捣碎，移入密闭瓶中保存。

2. 用40kg蒸馏水溶解50kg工业碳酸钾，边加热边搅拌，溶解后用三层滤纸滤去不溶杂质。在搅拌下慢慢将工业硫酸加到清亮滤液中，进行反应：

当溶液ph为5～6时，停止加酸，静置。沉淀完全后，过滤，离心甩干，用蒸馏水洗至犆犾－离子含量合格。按每10kf硫酸钾加水7.5kg的量加入适量蒸馏水，搅拌下慢慢加入分析纯硫酸（每10kg硫酸钾加9kg硫酸），通蒸汽加热使之全部溶解：

加入少许洗净的活性炭，加热搅拌片刻，趁热减压过滤。将清亮透明的滤液在80～100℃加热蒸发（蒸发时防止暴沸），当密度为1.65～1.68时停止加热，自然冷却结晶，待结晶完全时（约25～30℃），取出甩干，于100℃烘箱内烘干即可。
