"In organic chemistry, a Schiff base (named after Hugo Schiff) is a compound with the general structure R R C=NR (R = alkyl or aryl, but not hydrogen). They can be considered a sub-class of imines, being either secondary ketimines or secondary aldimines depending on their structure. The term is often synonymous with azomethine which refers specifically to secondary aldimines (i.e. R−CH=NR' where R' ≠ H). " - Imine types

This cross-reactive binding was elucidated by theoretical and nuclear magnetic resonance (NMR) studies.

WitrynaMine dewatering is the action of removing groundwater from a mine. When a mine extends below the water table groundwater will, due to gravity, infiltrate the mine working. On some projects groundwater is a minor impediment that can be dealt with on an ad-hoc basis. In other mines, and in other geological settings, dewatering is fundamental to … WitrynaThe main focus is on those which are based on imine type ligands.
