周期表第一组包括锂,钠,钾,鉫,铯和钫六个元素,本章只择取钠和钾做典型讲授,其他却可类推。钠的化合物本来应以氢氧化钠为重点,但因在第一册卤素一章中,已经谈及关于氢氧化钠的制法,所以现在只把碳酸钠的制法作为重点来谈。本书的编译,既能尽量吸取苏联课本的优点,又能联系中国实际,结合爱国主义来谈,这是非常适当的。我国著名化学工程专家侯德榜氏所创造的碳酸纳制法,已经在国际采用,这是我们祖国的光荣;所以本书特把侯氏制硷法简单介绍出来,综合就是五个步骤如下:
The first group of the periodic table includes six elements of lithium, sodium, potassium, gallium, cesium and gallium, this chapter only choose sodium and potassium as the typical teaching, others can be analogized. Sodium compounds were supposed to focus on sodium hydroxide, but as sodium hydroxide has already been discussed in Chapter 1 of the Halogen chapter, the current focus is on sodium carbonate. This book compilation, both try to learn the advantages of the Soviet textbooks, but also contact the reality of China, with patriotism to talk about, it is very appropriate. China’s famous chemical engineering expert Houde Bangshi created by the carbonated sodium system has been adopted in the international arena, which is the glory of our motherland; so this book specifically put out a brief account of Hou’s alkaline law, the comprehensive is the five steps are as follows:
