The seminal origin of what is considered “green chemistry” today might be ascribed to the launch of the Responsible Care® initiative by the American Chemistry Council (ACC) [1] and to the ...
متن کاملGreen Chemistry Metrics with Special Reference to Green Analytical Chemistry.
The concept of green chemistry is widely recognized in chemical laboratories. To properly measure an environmental impact of chemical processes, dedicated assessment tools are required. This paper summarizes the current state of knowledge in the field of development of green chemistry and green analytical chemistry metrics. The diverse methods used for evaluation of the greenness of organic syn...
متن کاملGreen Chemistry CRITICAL REVIEW
In this paper both the mechanistic and kinetic aspects of furfural formation from pentoses in aqueous acidic media have been reviewed. Based on the reviewed literature, a comprehensive reaction mechanism has been proposed consisting of more than one route, all starting from acyclic xylose, and involving alternately 1,2-enolization, β-elimination or isomerization via 1,2-hydride shift as key ste...
