Acetaldehyde is oxidized over silica gel with the help of air. The mixture is passed over that catalyst at 387 K (114°C). The outgoing dry gases are found to contain 4.85% CO,, 8.65% acetaldehyde, 14.9% acetic acid, 2.55% O, and 69.05% N, by volume (on dry basis). For carrying out dry analysis, water was first removed from the mixture. During the water removal, some acetic acid is also condensed. Calculate: (a) the percentage conversion of acetaldehyde, (b) the percentage yield of acetic acid, (c) mass ratio of air to acetaldehyde in incoming feed, (d) the percentage removal of acetic acid during the removal of water, and (e) that actual analysis of the gases leaving the reactor.

Transcribed Image Text:4.14 Acetaldehyde is oxidized over silica gel with the help of air. The
mixture is passed over that catalyst at 387 K (114°C). The outgoing dry
gases are found to contain 4.85% CO2, 8.65% acetaldehyde, 14.9%
acetic acid, 2.55% Oz and 69.05% N, by volume (on dry basis). For
carrying out dry analysis, water was first removed from the mixture.
During the water removal, some acetic acid is also condensed.
Calculate: (a) the percentage conversion of acetaldehyde, (b) the
percentage yield of acetic acid, (c) mass ratio of air to acetaldehyde in
incoming feed, (d) the percentage removal of acetic acid during the
removal of water, and (e) that actual analysis of the gases leaving the
reactor.
