硫酸钾制备

１．曼海姆法用98%硫酸和氯化钾在高温下进行分解反应，生成硫酸钾，副产盐酸。

２．结晶分离法用桐子壳碱或草木灰碱经焙烧、浸取、过滤、浓缩、离心分离、干燥制得硫酸钾。

３．明矾石还原热解法将明矾石粉碎、焙烧脱水，然后经脱色、用烧碱溶液浸取、脱硅、浓缩、分离得到粗硫酸钾，经精制制得硫酸钾成品。

4.将55mL浓硫酸(相对密度1.84)溶于120mL水中，慢慢地加入50%的KOH溶液，直至溶液呈弱碱性，使反应液的温度在1h内上升至80～100℃，过滤，将滤液用稀硫酸酸化至pH值为5左右。蒸发浓缩至析出结晶，分离出的结晶可再进行重结晶提纯。产品在70～100℃下进行干燥。

硫酸钾的提纯法：将市售硫酸钾在乳钵中研成粉末，将其慢慢地加入到沸腾的水中，并充分搅拌使其溶解，直至不再溶解为止。加入少量水使盐全部溶解并稍有过量，趁热过滤。将滤液冷却，将结晶抽滤出并用少量水洗涤。洗出液与滤液合并后，蒸发浓缩，冷却后又可析出结晶。所得结晶与前面制得的结晶一起进行干燥。

5.边搅拌边缓慢地将50%的氢氧化钾溶液加到含量约为45%的硫酸溶液中，至石蕊呈碱性反应为止：

将反应液在1h内加热到80～100℃，过滤，滤液用分析纯硫酸酸化到石蕊呈弱酸性，蒸发浓缩，过程中注意将析出的结晶取出，然后，滤干，在70～100℃下干燥，即得分析纯硫酸钾，若再进行重结晶，可得优级纯硫酸钾。也可采取碳酸钾和10%的硫酸反应制得硫酸钾。
