摘要
设计了一个在试管中利用NaNO3和KCl通过转化法制备KNO3的微型实验.该实验试剂用量仅为常量实验的1/10,反应装置简单.反应时间只需43min,产率达75%以上,产品质量合格.
The microscale experiment,from which potassim nitrate was prepared in test tube via the method of transformation,was designed.In this method,the quantity of reagents is only one tenth of the constant experiment,and the reaction device is simply.The reaction time is 43 minutes and the yield reaches more than 75%,and the product quality is qualified.
