Atom economy is the core content of green chemistry, the concept as early as 1991, United States of the famous organic chemist Trost of Stanford University (for this he was awarded the 1998 "Presidential Green Chemistry Challenge Award" academic award) proposed, that is, raw material exactly wh...
aconsiderable effort is being made on the advancement of green chemistry using protocols having less environmental impact, maintaining higher atom-economy and recyclability. 可观的努力在绿色化学的推进被做使用协议有较少环境影响、维护的更高的原子经济和recyclability。 [translate] ...
A series of silica gel immobilized lanthanum catalysts were prepared for the atom-economy synthesis of N-substituted carbamates from urea derivatives and dimethyl carbonate. The La/SiO_2 catalysts with lanthanum loadings varied from 1.3 wt% to 8.5 wt% were characterized by AES, BET, XRD, TEM,...
Catalysts are a major contributor to the global economy. Over 90% of chemical processes require catalysts and there is a continuous demand for the development of more effective, inexpensive, and green catalysts to secure a sustainable future for our society1. As defined by Berzelius in 1835, a...
