A fictional company has been producing propene oxide, C3H6O,from propene, C3H6, with a 96.0%yield. The process requires the useof a compound called m-chloroperoxybenzoic acid, C7H5O3Cl,which can be abbreviated as mCPBA. The entire reaction takes placein the solvent dichloromethane, CH2Cl2:
C3H6+C7H5O3ClCH2Cl2????96.0% yieldC3H6O+C7H5O2Cl
The initial propene concentration in the solvent is 21.0g/L.
Consider the prices of the following substances.
Substance | Price per unit | Unit |
propene | $10.97 | kg |
dichloromethane | $2.12 | L |
mCPBA | $5.28 | kg |
propene oxide | $258.25 | kg |
Also consider that the cost of waste disposal is $5.00 perkilogram of propene oxide produced.
Part A
A relatively simple way of estimating profit is to consider thethe difference between the cost (the total spent on materials andwaste disposal) and the earnings (the price at which the productcan be sold).
Calculate the profit from producing 32.00kg of propeneoxide.

The company is developing a \"greener\" method of making propeneoxide from propene using hydrogen peroxide, H2O2, in supercriticalwater with a vanadium catalyst. In the reaction 1.00 kg of vanadiumcatalyst and 32.0 kg of water are used for each kilogram ofpropene. 75 % of the vanadium catalyst can be collected and reusedin a subsequent batch:
C3H6+H2O2V, H2O????89.0% yieldC3H6O+H2O
Consider the prices of the following substances.
Substance | Price per unit | Unit |
propene | $10.97 | kg |
hydrogen peroxide | $1.96 | kg |
vanadium catalyst | $57.50 | kg |
supercritical water | $1.85 | kg |
propene oxide | $258.25 | kg |
There is virtually no waste produced with this green process andthere is no waste disposal fee, but the yield is only 89.0%.
Part B
Calculate the profit from producing 32.00kg of propene oxide bythis alternative green process.
