【摘要】：硫酸分解氯化钾制备硫酸氢钾可在水相和无水相中反应进行。分别探讨了工业硫酸在两种工艺条件下,反应温度、原料物质的量比、反应时间以及硫酸浓度对产品硫酸氢钾的影响。通过单因素实验和正交实验,得到水相最优工艺条件:反应温度为90℃、硫酸与氯化钾物质的量比为1.2∶1、反应时间为60 min、硫酸浓度为80%(质量分数,下同),在此条件下转化率可达98.64%;无水相最优工艺条件:反应温度为80℃、硫酸与氯化钾物质的量比为1.1∶1、反应时间为60 min、硫酸浓度为70%,此时转化率可达92%。
[Abstract]:The preparation of potassium bisulfate by decomposition of potassium chloride with sulfuric acid can be carried out in aqueous phase and anhydrous phase. The effects of reaction temperature, ratio of raw materials, reaction time and concentration of sulfuric acid on potassium bisulfate were discussed. Through single factor experiment and orthogonal experiment, the optimum technological conditions of aqueous phase were obtained as follows: reaction temperature 90 鈩，
