萃取是化工工艺流程中的重要工序,合适、合理的萃取剂能保证化工工艺流程的顺利进行,提高化工生产的经济合理性。结合化工工艺流程简介,现对化工生产中萃取剂选择的基本原则作浅要论述,并在此基础上探讨出了几点相应的萃取剂选择方法,以供相关人士参考。 Extraction is an important process in the chemical process, suitable and reasonable extractant to ensure the smooth progress of chemical processes and improve the economic rationality of chemical production. Based on the brief introduction of chemical process flow, the basic principles of extraction agent selection in chemical production are briefly discussed. On this basis, some corresponding extraction agent selection methods are discussed for the reference of relevant parties.
