Abstract “Industrial synthetic ammonia” is a typical technological content in textbooks. The technological content of “industrial synthetic ammonia” in the new senior high school chemistry textbooks of People's Education Press, Jiangsu Phoenix Education Press, and Shandong Science and Technology Press was analyzed and compared from both longitudinal and horizontal aspects. Through longitudinal analysis, it is found that the three editions of the textbooks transition from the compulsory phase focusing on simple and real perceptual knowledge to the selective compulsory phase focusing on cultivating complex and rigorous rational judgment ability, reflecting the advanced learning process. Through the horizontal comparison of content distribution, graph representation and column setting, it is found that the three textbooks are mainly technological knowledge, and the technological content of Jiangsu Phoenix Education Press is relatively brief. The graph representation of People's Education Press is better. The column of Shandong Science and Technology Press has a large number and a wide range. Based on the above research conclusions, it is suggested that textbooks should be compiled to enrich the technological content and reflect the technological development course; optimize graph selection to promote meaningful understanding. It is advisable for teaching to follow the order of arrangement, and pay attention to the extension of technological content; attach importance to industrial flow diagrams, and penetrate thinking methods.
