有关氯气的实验室制法,高中教科书第一册是用浓盐酸与MnO_2反应制得,但此反应不仅需要在加热的条件下进行,而且氯气产生的速率较慢。实验表明,用KMnO_4替代MnO_2,同时利用诱导效应,可使反应在常温下较快进行。1.实验装置(图1)。 For the chlorine laboratory method, the first volume of the high school textbook is prepared by reacting concentrated hydrochloric acid with MnO 2, but this reaction requires not only heating but also slow rates of chlorine production. Experiments show that, with KMnO_4 instead of MnO_2, while using the induction effect, the reaction can be carried out at room temperature faster. 1. Experimental setup (Figure 1).
