Q.1 and Acetaldehyde is oxidized over silica gel with the help of air. A mixture of acetaldehyde and (10) air is passed over a silica gel catalyst at 386 K. The following reactions take place CH3CHO + 02 - CH3COOH CH2CH0+02 - CH3COOH The outgoing dry gas is found to contain 4.58% CO2. 8.56% acetaldehyde, 15.26% acetic acid, 2.55% O2 and 69.05% N2 by volume on dry basis. For the purpose of dry analysis, water was first removed from the mixture and some acetic acid was also removed along with it. Calculate (i) the percentage conversion of acetaldehyde (ii) the percentage yield of acetic acid (iii) the ratio of air to acetaldehyde in the feed (iv) the percentage removal of acetic acid during the removal of water () composition of the gases leaving the reactor.
