What is the meaning of atom economy?
The atom economy of a reaction is a measure of the amount of starting materials that end up as useful products. It is important for sustainable development and for economic reasons to use reactions with high atom economy.
What is an example of atom economy?
A Diels-Alder reaction is an example of a potentially very atom efficient reaction that also can be chemo-, regio-, diastereo- and enantioselective. Catalytic hydrogenation comes the closest to being an ideal reaction that is extensively practiced both industrially and academically.
Is a higher atom economy better?
Inefficient, wasteful processes have low atom economies. Efficient processes have high atom economies, and are important for sustainable development, as they use fewer natural resources and create less waste.
What does high atom economy mean?
The atom economy tells us how efficient a reaction is. A reaction with a high atom economy is important for sustainability because it uses fewer natural resources and produces less waste. This means reactions with high atom economies are better for the environment.
Why atom economy is used in industry?
Atom economy is a way to measure the amount of useful product made in a reaction. It is a theoretical value that provides another way to evaluate a reaction process, alongside yield and efficiency.
What is yield and atom economy?
Percentage yield tells us how much of our reactants have been successfully converted into products, while atom economy tells us how many atoms in the reactants have been converted into our desired product.
What’s the difference between percentage yield and atom economy?
Atom economy gives information about the efficiency of the reaction whereas percentage yield gives information about how much product is made.
Why do you want a high atom economy?
Why do industries want a high atom economy? The atom economy tells us how efficient a reaction is. A reaction with a high atom economy is important for sustainability because it uses fewer natural resources and produces less waste. This means reactions with high atom economies are better for the environment.
Does a high atom economy mean a high percent yield?
Atom economy does not take into account yield and does not allow for the fact that many industrial processes deliberately use excess of reactants to increase the yield of a required product. Where atom economy proves useful, however, is in comparing different reaction pathways to a desired product.
Does high atom economy mean high percent yield?
Why is atom economy better than percentage yield?
Percentage yield tells us how much of our reactants have been successfully converted into products, while atom economy tells us how many atoms in the reactants have been converted into our desired product. Both are important factors to consider if you are manufacturing a product using a chemical reaction.
What affects atom economy?
Because addition reactions in general lead to the incorporation of all the atoms of the reactants into the final desired products, addition reactions result in high atom economy.
How does atom economy help in waste reduction?
The less waste there is, the higher the atom economy, the less materials are wasted, less energy used, so making the process more economic, ‘greener’ and more sustainable.
What is the difference between atom economy and percent yield?
Why is atom economy better than percent yield?
In an ideal process, all atoms in the reactants are used up by the process and are converted into reactants. Hence, no atom is wasted. But in actual processes, the atom economy is lower than 100%. This is due to the production of byproducts instead of giving only the desired product.
Does a high atom economy mean a reaction with a high yield?
Atom economy shows how many of the atoms used in the reaction turned into the product we want. Efficient reactions have high atom economies because they produce fewer waste products. Percentage yield is different from atom economy.
Why do we prefer atom economy over yield?
Determination of the atom economy is very important because it gives details about how greener the process is. It also indicates the waste of atoms during the process. Percentage yield is the amount of product given by a chemical reaction with respect to the expected calculated amount (the theoretical amount).
