Green Chemistry and Catalysis

The field of chemistry and chemical engineering termed as "green chemistry," or "property chemistry," focuses on the design of products and procedures that reduce the use and production of hazardous substances. In the backdrop of increasing awareness of the problems of chemical pollution and resource depletion, green chemistry arose from a range of preexisting concepts and analysis attempts such atom economy and contact action. Solvents are used extensively in many chemical synthesis processes as well as for cleaning and degreasing. Most ancient solvents are poisonous or chlorinated. On the other side, green solvents are typically made from renewable resources and biodegrade to harmless substances, usually a naturally occurring product. Contact action is the acceleration (increase in rate) of a chemical process in chemistry and biology by the suggestion of a substance known as a catalyst, which is itself not consumed by the reaction. A catalyst lowers the energy required to initiate a chemical reaction.
