Green Chemistry and Catalysis

Green Chemistry in Pharmaceutical Industries

In the pharmaceutical industries, there is a need for consideration of the waste product as a number of by-products are produced. Thus innovative strategies on chemistry are the core for pharmaceuticals, so the main point is gathering technology and chemistry to improve lives of patients and minimize environmental impact. Green chemistry also plays a major in developing innovatory drug delivery methods which are less toxic and more useful, effective with minimum side effects and could help millions of patients

In the past years, for the production of Adipic acid industrially, benzene is used as a beginning material (Benzene is one of the basic chemicals for industrial reactions and a solvent). It is known that it derives mainly from the refining processes of the petrochemical industry. Later the starting material became cyclohexanone or a mixture of cyclohexanone and cyclohexane. For the oxidation process it was used nitric acid, producing toxic fumes of nitric oxides, which are also responsible to the greenhouse effect and the destruction of the ozone layer in the stratosphere. It was certain that the method had to be changed again with more environmentally cordial reactions.
