The process requires the use of a compound called m chloroperoxybenzoic acid, ChH5 O3Cl, which can be abbreviated as mCPBA. The entire reaction takes place in the solvent dichloromethane, CH2 Cl2 The word "green" has come to mean "environmentally friendly." Green chemistry is an international initiative to make all industrial products, CH2Cl2 C3H6 C7H503 Cl C3H60 C7H502 Cl processes, and chemical reactions compatible with a sustainable society and environment. It encourages manufactures to use practices 96.0% yield. that result in reduced waste and reduced use of energy and The initial propene concentration in the solvent is 21.0 g/L resources Consider the prices of the following substances Green chemistry can be summarized by twelve basic principles Substance Price per unit Unit 1. Prevent waste $10.97 kg 2. Maximize reactant use propene 3. Use less toxic reactants and produce less toxic dichloromethane $2.12 L byproducts 4. Products should have minimal toxicity $5.28 kg mCPBA 5. Solvents should be lower toxicity and used sparingly 6. Energy usage should be minimized propene oxide $258.25 kg 7. Raw material should be renewable 8. Minimize extra synthesis steps Also consider that the cost of waste disposal is $5.00 per kilogram of propene oxide produced. 9. Use catalysts 0. Products should biodegrade after their usefu etime 11. Reactions should be monitored for pollution production Part A 12. Chemicals should minimize the potential for accidents A relatively simple way of estimating profit is to consider the the difference between the cost (the total spent on materials and waste disposal) and the earnings (the price For industry to adopt a green process, there is also the need to at which the product can be sold) demonstrate that it is economically feasible. Calculate the profit from producing 52.00 kg of propene oxide Express your answer numerically in dollars using three significant figures. 75000 Subm Hints My Answers Give Up Rev Part

Explanation / Answer

Part A)

Cost of reactants = 10.97 x 39.245 + 161.01 x 5.28 + 2.12 x 1.9 = $1285

Cost of product = 258.25 x 52 = $13429

Waste = 5 x 52 = $254

Profit = $11890

Part B) For the given V catalyzed reaction

cost of reactants = 10.97 x 42.08 + 1.96 x 34.015 + 57.7 x 42.08 + 1346.6 x 1.85 = $5447.513

cost of product = 258.25 x 52 = $13429

cost of recovered reactants = 10.97 x 4.42 + 1.96 x 3.572 + 57.7 x 31.56 = $1876.5

Profit = 13429 + 1876.5 - 5447.5 = $9858
