Methyl acetate is industrially synthesized via the equilibrium reaction
CH3COOH(l)+CH3OH(l)⇌CH3COOCH3(l)+H2O(l)ΔHrxn∘=−25kJ mol−1
A competing side reaction converts methanol to dimethyl ether at elevated temperature. Considering both equilibrium yield and suppression of the side reaction, which strategy is most effective for maximizing production of methyl acetate?
(a) Add an inert gas to raise the total pressure and shift the equilibrium right.
(b) Use a moderate temperature with continuous removal of water from the reaction mixture.
(c) Use a high temperature to increase reaction rate and avoid water accumulation.
(d) Increase the concentration of water at constant temperature to drive the equilibrium forward.
