Objectives 1. To appreciate the history of chemical accidents and how Green Chemistry can be used to design safer products and industrial systems without harming the environment and subsequent human health. 2. To understand the historical and current role of chemicals in our society and economy. 3. To qualitatively and quantitatively examine the impacts on human health and the environment of chemical products and processes. 4. To recognize the tools available to scientists and engineers in the design and synthesis of new chemical products and processes including energy efficiency. 5. To have a basic knowledge of toxicity and the molecular basis of hazard. 6. To analyze the efficiency of various approaches to chemical design. 7. To understand the transformational role of Green Chemistry in the global economy and the associated material and energy benefits.
Subject Why Green Chemistry? - Current Problems • Ecosystems • Lithosphere (Waste, resource depletion) • Atmosphere (CO2, Ozon, three-way catalysis in automobile…) • Hydrosphere (microplastics, salt, desalination, heavy metals) • Biosphere (toxicity) • Energy (renewable)

What is Green Chemistry? • The Twelve Principles of Green Chemistry • Green Metrics

Solvents • Synthesis in water and benign solvents • Ionic liquids • Supercritical solvents • No solvent at all - mechanochemistry

Alternative Synthesis Concepts • Mechanochemistry • Photochemistry (TiO2, water splitting, photooxidation in water treatment) • Microwave • Ultrasound • Flow reactor • Continuous manufacturing • Metal-free syntheses • Biological syntheses

Catalysis (homogeneous and heterogeneous, zeolites)

Resources • Alternative feedstock • Upcycling of waste and use of waste products • Using natural resources: problems and prospects • Biomass (biomass-derived reactants, biofuels, bioreforming) • Waste reduction • Synthesis using green reagents • Metals (Li, raw earthes) • Chemical degradation and reuse

Products • Design of safer chemicals (drugs, toxicity, pesticides, reducing carcinogenity, etc. reducing ecotoxicity,(book 9) • Sustainable materials (polymers, inorganic materials, footprint) • New technologies (solar, supercap, energy storage)

Evaluate the Synthesis • Tools for green chemistry (estimate fate, exposure, effect of chemicals) • Concept of life cycle assessment • How to Plan a Green Synthesis (DOE)
