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...
Taught Science (mainly Chemistry, Physics and Math) at high school level and has a Master's Degree in Education. Atom economy is a measure of the desired useful products formed from reactants in a chemical reaction. It can also be called atom efficiency or percentage atom economy. The highe...
3.This paper has compared a green chemistry technology of ammonium eerie nitrate with the classical technology by atom economy.从原子经济性出发,对以碳酸铈为原料合成硝酸铈铵的绿色化学工艺与传统工艺进行了对比。 4.In order to make the atom economy more clear, the rearrangement reations addition rea...
1)atom economy原子经济 1.With analyzing the atom economy theory,the importance of it are expatiated,especially on that it brings about a great advance in catalytic reaction,bioengineering,life science,electrosynthesis,supercritical fluid,organic synthesis technology (eg.通过对原子经济性的分析,深刻阐述了...
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/SiO2 catalysts with lanthanum loadings varied from 1.3 wt% to 8.5 wt% were characterized by AES, BET, XRD, TEM, ...
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,...
method by which the compound is prepared or itssynthesis. In order to focus greater attention on waste by-products that are formed during a synthesis, Barry Trost of Stanford University developed the concept of atom economy. This concept deals with the question: How many of the atoms of the ...
The results of various DFT versions are generally quite effective, although this comes from a cancellation of errors. Nevertheless, great progress has been made. At present many chemists prefer the DFT method (economy and accuracy) than getting stuck at the barrier of the configuration interaction ...
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] ...
