Green Chemistry- What is it all about?

By Liam Koger

Green Chemistry• Green Chemistry is a idea that has now become a

need. It links chemical reactions to the world in which they happen and inspires chemists to think of the penalties of using certain reactants, or allowing products to get into the environment.

12 Principles of Green Chemistry

1. Prevent WasteMinimize waste2. Design safer chemicalsDesign chemicals that are less harmful to the environment3. Find safer ways to make synthetic productsDiscover different ways that you can produce synthetic products4. Maximize atom economy Plan combinations so that the last produce has the most quantity of the starting resources. 5. Use safer solventsUse less harmful or dangerous chemicals6. Use renewable reactantsProducts that can be reused create a much cleaner environment

7. Maximize energy efficiencyDo tests to find the right temperature and pressure8. Avoid chemical derivativeDerivatives use extra substances and produce waste.9. Use catalysts whenever possibleCatalysts are used in small quantities and can carry out a single reaction many times.10. Design biodegradable productsMake products that can be broken down to prevent waste11. Use real time analysis to prevent pollutionlessen or remove the formation of by-products12. Minimise the potential for accidents Find safer methods

Task 2- Case study

• (a) A brief explanation of exactly how the company or organization used Green Chemistry.

Dow Chemical Company changed hydrogen peroxide to propylene oxide, this massively advances the making procedure of a key chemical intermediate, propylene oxide. These can be used for insulation, appliances, automobiles and brake fluids. • (b) How Green Chemistry was used by the company or organization.For this case study Dow chemical company have used the principles numbers 2,3,5,9. there main principle that Dow used was a catalyst when they advanced the making procedures.

• (c) The benefits to the company and to the environment that arose from the Green Chemistry initiative.

They were awarded Presidential Green Chemistry Challenge Award for there use of green chemistry. It recognizes advance technologies that transfer sustainability principles from the study lab into the real world to allow environmentally responsible and economically applied routes to commercial chemical manufacturing
