绿色化学原则在发展

从源头上减少或消除化学污染是绿色化学的理想,而绿色化学原则是对绿色化学内涵最好的诠释。自Anastas等在1998年提出12条绿色化学原则以来,Anastas本人和Winterton又从技术、经济和商业等角度出发,分别提出了另外12条绿色化学补充原则。但这些原则缺乏清晰地反映与环境影响高度相关的概念,绿色工程的概念和绿色工程原则由此应运而生。Tang等随后将Anastas等提出的绿色化学原则和绿色工程原则简化为IMPROVEMENTS PRODUCTIVELY中字母表示的24条原则,以便于记忆、交流和推广。然而,上述原则主要是直觉和常识的结晶,难以清晰地反映绿色化学的目标和相关研究领域的内在联系。预计从绿色的认定,原子经济性和有效质量收率等的兼顾,生命周期评价数据的采集,催化剂的性质及其反应、分离和循环使用的一体化以及绿色程度评价指标和评价方法的优化与平衡等几方面发展和凝炼绿色化学原则将是长期的研究课题。

Developing the Green Chemistry Principles

To reduce or eliminate chemical pollution in origin is the ideal of green chemistry,while its principles are the best elucidation for its essence.Based on the 12 well-known principles proposed by Anastas et al.in 1998,the 12 more principles were complemented by Anastas himself and Winterton,respectively from technical,economic and commercial considerations.Unfortunately,these principles don't explicitly include concept which is highly relevant to environmental impact.As a result,the concept of green enginee...
