Abstract: The paper firstly reviews the development and research progress of the basic issues，such as definition and principles of green chemistry and chemical technology as well as quantitative description of greenness and “non-green problems” in the research of green chemistry and chemical technology，and secondly explores and studies the questions， such as how to complement the present basic principles，i.e.，the twelve principles，whether green chemistry should be separated into an independent discipline or not，and how to describe and evaluate effectively the greenness of green products (green chemistry) and green processes (green chemical technology). The twelve principles are considered still the guiding principles to study green chemistry，but two new principles could be added，that is，design and manufacture of materials which could be reclaimed and used time after time，such as catalysts，chiral reagents etc.，as well as improvement of former processes and techniques by using process intensification and integration etc. Green chemistry and chemical technology should be an independent discipline to be studied more deeply. The greenness of products and processes could be quantitative described，but different parameters and methods must be chosen depending on different objectives. In the same time， more attention should be paid to studying and solving the “non-green problems”，such as research on ionic liquids etc.

摘要： 对绿色化学化工的定义、原则、绿色度的定量化以及绿色化学研究中出现的“绿色非绿”等基本问题的发展及研究进展进行了综述。在此基础上，对绿色化学的基本原则是否需要做必要的补充、绿色化学是否应该单独成为一门学科，以及如何更加有效地定量描述和评价产品的绿色度(绿色化学)和制造过程的绿色度(绿色化工)等基本问题进行了探索和研究。研究结果认为：绿色化学的十二原则仍然是今后绿色化学化工研究的指导原则，但应增加设计并制备可回收并反复使用的物质，如催化剂、手性试剂等，以及使用过程强化及集成方法，改进原有化工工艺，以提高生产效率和减少能耗等两条原则；绿色化学应该成为一门独立的学科而加以深入的研究和发展；绿色化学中的绿色度是可以量化的，但要根据不同的目标选择合适的评价参数和方法；同时要特别注意研究和克服离子液体等绿色化学研究中出现的“绿色非绿”问题。
