绿色化学诞生于上世纪90年代,其目标是研究和寻找能充分利用的无毒害材料,最大程度地节约能源,在各环节都实现净化和无污染的反应途径。它的最大特点是从始端就采用实现预防污染的科学手段,因而过程和终端为零排放和零污染,具体体现在“5R”上——减少用量(Reduction),重复使用(Reuse),可回收(Recycling),能再生(Regeneration),排斥(Rejection)有毒物[1]。化学是一门以实验为基础的学科,教材中很大比例的知识是通过实验引入或阐述的。因此,在平时的教学中,从化学
Green chemistry was born in the 90s of the last century with the goal of researching and searching for fully exploitable, non-toxic materials, maximizing energy savings and purifying and pollution-free reactions at all stages. Its most prominent feature is the adoption of a scientific approach to pollution prevention from the beginning, resulting in zero emissions and zero pollution at the process and end, as embodied in “5R ” - Reduction, Reuse, Recycling, Regeneration, Rejections Toxic [1]. Chemistry is an experiment-based discipline, a large proportion of which is introduced or elaborated through experiments. Therefore, in the usual teaching, from chemistry
