Organic synthesis using clay catalysts

The clay minerals can catalyze a variety of organic reactions occurring on their surface and interstitial space. Synthetic organic chemists have been attracted to their tremendous potential as catalysts only relatively recently. Modification of their properties by incorporating different metal cations, molecules or complexes, can lead to catalysts that are useful in effecting even more

WeatheringClay Minerals

Distinguishing Clay Minerals Generally, the clay minerals occur as such small mineral grains that they cannot be easily distinguished in either hand specimen or thin section. However, the smectites can be distinguished from the other clays in the field by the eating test - place some clay in your mouth.

Culture medium Definition, Preparation, Classification

2021/12/10Buy Now. A culture medium is a solid or liquid preparation utilized to grow, transport, and store microorganisms. To be useful, the medium must hold all the nutrients the microorganism needs for germination. All the microorganisms demand basic requirements, although there is a variation as to the application of organic and inorganic compounds.
