Chemical Synthesis and Industrial Applications of Catechu
Abstract: Kattha is acquired by crystallization in cold from the water extractives of the heartwood of Acacia catechu. The main constituents of the red heartwood are catechin and catechu tannic acid along with small proportion of brown coloring matter. It also contains tannin, flavotannin, gallotannin, hloratannin etc. (+)-Catechin is a constituent, which decreases the action of some hormones; hence “tyronorman” injected with thyroxin terminates the upsurge in basal metabolism. It has …

AN OUTLINE OF KINETICS VERSUS THERMODYNAMICS CHEMISTRY
Abstract: Nearly all chemical reactions has a kinetic and a thermodynamic feature. The terms ‘kinetic’ and ‘thermodynamic’ though inter-related are two diverse aspects of a chemical reaction. This paper represents an outline of the underlying relationships between the two through application to chemical reactions and an example from natural processes. A required condition for thermodynamic control is reversibility or a mechanism allowing the equilibration between products. In this manner, the thermodynamically …
