From the point of view of atom economy aneffective atom utilizationAUe, in which the consumed energy in the chemical process is accounted in the form of equivalent carbon amount, was proposed to more completely scale the atom economy level of the process. ...
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, ...
The green metrics atom economy (AE) and reaction mass efficiency (RME) are introduced and discussed. Following literature definitions, examples of reactions appropriate for upper-level undergraduate students are provided to illustrate how the metrics are calculated. In the case of atom economy, ...
