Use catalysts, not stoichiometric reagents: Minimize waste by using catalytic reactions. If you have health and safety related questions, visitHSE.gov.uk. Catalysts are used in small amounts and can carry out a single reaction many times. Use renewable feedstocks: Use raw materials and feedstocks that are renewable rather than depleting. Derivatization necessitates the use of extra energy and reagents and will lead to extra waste generation in the synthesis. There is a commonly held view that only 'first-order' derivatives should be considered: substances that can be created from a parent structure in a single chemical reaction. Design less hazardous chemical syntheses: Design syntheses to use and generate substances with little or no toxicity to humans and the environment. Maximize atom economy Make sure that a greater percentage of the atoms present in the reactants of a chemical reaction are used in the products that are also usable. Use safer solvents and reaction conditions 6. Maximize atom economy. One of the key principles of green chemistry is to reduce or avoid derivatization in a chemical reaction. Avoid chemical derivatives: avoid using blocking or protecting groups or any temporary modifications if possible. https://en.wikipedia.org/w/index.php?title=Derivative_(chemistry)&oldid=1120578991, This page was last edited on 7 November 2022, at 19:09.
