Ethyl p-aminobenzoate was produced by the H2SO4 acid-catalyzed, reversible reaction of paminobenzoic acid and ethyl alcohol, as depicted below. Briefly explain why one reactant (the one that's cheaper and more easily separated during work-up) was used in excess.
Calculate the kg of fuel used for 100 kg mol of outlet ?ue gas and the kg mol of air used. (Hint: First calculate the mol O2 added in the air, using the fact that the N2 in the ?ue gas equals the N2 added in the air. Then make a carbon balance to ..
