The book is the research work of PhD degree in the form of thesis. I want to publish with ISBN. It is about the kinetic study of oxidation of some pharmaceuticals with oxidizing agent potassium dichromate. The pharmaceuticals studied are Voglibose, Pregablin, Cetrizine, Quetiapine, Domperidone and Rasagiline. The effect of variation of concentration of substrates and oxidizing agent. Similarly, the effect different temperatures on the kinetics was also studied.
