WebbIn the original method for making ibuprofen the atom economy was 40%. However, a new way of making ibuprofen was invented in the 1980’s that had an atom economy of 77%. This means there is less waste to dispose of and so is a “greener” way of making ibuprofen. The method is also cheaper. WebbWhat is the difference between percentage yield and atom economy? Percentage yield is an experimental value calculated based on obtained results whereas atom economy is a theoretical value measured according to a balanced equation.
WebbHey guys, i've been given a double sided spread on calculations for atom economy and percentage yield and i really do not understand it. I understand atom economy easier … WebbSince all three H atoms of BH3 are used in the reaction, the theoretical atom economy is relatively high. Unfortunately, the experimental atom economy is not as high, because an excess of borane must be used. PRE-LAB QUESTIONS: 1.
