Hydrophobic Silica Gel Impregnated with Copper ii Complex of 2S4R2RSW2hydroxydodecyl4hydroxyproline

The structure of the selector is shown in Figure 1. Chiralplate and HPTLC-CHIR are the only precoated plates built up from such material. The chiral layer on the latter plates is combined with a so-called 'concentrating zone'. The sample to be separated is applied to this small band and is transported with the solvent front, forming a narrow band at the interface of the two sections; consequently, a higher efficiency of the separation process is obtained.

Many racemates have been resolved on both layers by ligand-exchange chromatography (LEC). The separated enantiomers are those capable of forming diastereomeric complexes of different stability with the metal ion and the chiral selector. The requirement of sufficient stability of the ternary complex involves five-membered ring formation and compounds such as a-amino and a-hydroxy acids are the most suitable.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
