毛主席教导我们:“不论做什么事,不懂得那件事的情形,它的性质,它和它以外的事情的关联,就不知道那件事的规律,就不知道如何去做,就不能做好那件事。”在化学工业中进行科学试验和技术革新时,常常需要知道:某一化学反应能否进行?如何为某一化合物选择合适的溶剂或萃取剂?某一化合物能否导电?某一化合物是否是半导体?等等各种各样的问题。这就需要了解、掌握各种化合物的物理、化学性质。如果能有某种理论方法,对未知化合物的性质作出预见,就可以帮助我们制定试验计划,
Chairman Mao taught us: “No matter what we do or do not know about it, its nature, its association with anything other than it, we do not know the law of that matter, we do not know how to do it, we can not Do that. ”When conducting scientific experiments and technological innovations in the chemical industry, it is often necessary to know whether a chemical reaction can proceed or not, how to choose a suitable solvent or extractant for a compound, whether a compound can be conductive Whether a compound is a semiconductor? And so on a variety of issues. This requires understanding and mastering the physical and chemical properties of various compounds. If there is some theoretical way to predict the nature of unknown compounds, we can help to develop a trial plan,
