我们用如下装置进行合成氨的实验,简单易做效果很好。 如图,A试管为产生H_2部分,加入废电池壳和1:4的硫酸。 B试管产生N_2,选择能套入A的试管,加入约试管1/3的固体NaNO_2和饱和NH_4Cl溶液,使其发生反应不会溢出管口为宜。微热后套装入A试管,然后将支管连接干燥管。 C管内装入催化剂,并在两端堵上棉花作固定催化剂用。催化剂的处理,将打火石研细、
We use the following devices to conduct ammonia synthesis experiments, which are simple and easy to use. As shown in Fig. A, the tube was used to produce the H_2 portion, and the waste battery shell and 1:4 sulfuric acid were added. B tube to produce N_2, select the tube can be set in A, add about 1/3 of the test tube solid NaNO 2 and saturated NH 4 Cl solution, so that it does not overflow the nozzle is appropriate. After micro-heating, set it into A test tube, then connect the branch tube to the drying tube. The C tube was charged with a catalyst, and cotton was plugged at both ends for fixing the catalyst. The treatment of the catalyst will refine the flint
