1、浅谈绿色化学化工的发展摘要: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
2、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。关键词:绿色化学;绿色化学化工;绿色度定量化;绿色非绿DevelopmentandresearchonbasicissuesofgreenchemistryandchemicaltechnologyJIHongbing1,SHEYuanbin2(1SchoolofChemicalEngineering,SouthChinaUniversity
