我在讲授塔式法制取硫酸时,应用了如下装置进行演示。如工业上一样地利用黄铁矿为原料,能在较短的时间内制得硫酸,主要装置附于铁架上,这样也易于移动与掌握,今介绍如下:演示进行的程序:首先分别以酒精灯加热小烧瓶5(拟格氏塔中的供水装置)和试管2(拟燃矿炉),至水沸腾蒸汽入于吸滤瓶7时,此时 FeS_2已红热,这时可一手不断压缩橡皮袋,鼓入空气使 FeS_2燃烧生成
When I was teaching tower method to take sulfuric acid, I used the following device to demonstrate. As industrial use of pyrite as raw material, sulfuric acid can be produced in a relatively short period of time, the main device attached to the iron frame, it is also easy to move and grasp, this is introduced as follows: Demonstration of the process: First, respectively Alcohol lamp heating small flask 5 (to be the tower’s water supply device) and test tube 2 (to be burned furnace), until the water boiling steam into the suction flask 7, then FeS_2 has been red hot, this time with one hand Compression rubber bag, drum into the air to generate combustion FeS_2
