Eco-Friendly Approaches to Chemical Synthesis | Chapter 2 | Recent Developments in Science and Technology for Sustainable Future

 Green Chemistry entails revolutionary advancements in compound exploration and production, aimed at reducing or eliminating the use and generation of hazardous substances in the manufacturing, design, and applications of chemicals. The rapid evolution of Green Chemistry is propelled by the realization that environment friendly products and methodologies are not only ecologically responsible but also economically viable in the long run. In the development of new components, yields, or processes, researchers and engineers adhere to a framework that diverges from conventional manufacturing practices, prioritizing considerations of environmental impact, economic feasibility, and societal well-being. This adherence is guided by the twelve principles of Green Chemistry, which comprehensively address the interplay of environmental, economic, and public factors. This chapter provides a concise overview of Green Chemistry in synthetic methods, delving into various techniques such as mechanochemistry (grinding), photochemical processes, ultrasound or sonochemical methods, microwave irradiation, and solvent-free conventional thermal heating. Each of these methods exemplifies the commitment to sustainable and environmentally benign practices in chemical synthesis.

Environmentally Benign Un-Catalyzed Esterification of Alcohols under Solvent-Free Condition Using Acetyl Chloride: An Experimental Investigation| Chapter 3 | Recent Trends in Chemical and Material Sciences Vol.6

 Under solvent-free and energy-efficient circumstances, a generic and practicable approach for un-catalyzed esterification of alcohols using acetyl chloride is disclosed. Nowadays, catalyst- and solvent-free processes are far more safe, nontoxic, ecologically friendly, and cost-effective. This approach is economical and environmentally friendly due to its high yields, extensive applicability to diverse alcohols, mild reaction conditions, short reaction time, and ease of operation. Because of the benefits of the approach, which include solvent-free, catalyst-free, energy-efficient, and ecologically friendly circumstances, a simple work-up procedure, and easy and green separation of the produced HCl, this protocol will be a green technology for practical organic synthesis.
