这一实验演示是否成功受诸多因素的影响,如氨水浓度、鼓入空气量及速度、催化剂等等.由于这些条件都不易掌握,特别是当催化剂采用铂丝时,其热容量较小,还末接近液面便冷下来,所以一般不易成功.笔者在研究过程中发现此实验是否成功的关键是如何使反应起始时催化剂有足够的温度.根据这一关键进行了实验,当催化剂与反应物(NH_3气、O_2)
This experiment demonstrates whether or not the success is affected by many factors, such as ammonia concentration, air volume and velocity, catalysts, etc. Since these conditions are not easy to grasp, especially when the catalyst uses platinum wire, its heat capacity is small and it is not yet finished. It is generally not easy to succeed because the liquid level is close to the temperature. The key to the success of this experiment in the course of the study was to determine how to make the catalyst have sufficient temperature at the beginning of the reaction. According to this key experiment was conducted when the catalyst and reactants were used. (NH_3 gas, O_2)
