A study was made of the conditions for the synthesis of unsymmetrical dialkyl carbonates by the carbonylation of a mixture of saturated aliphatic alcohols with carbon monoxide in the presence of mercuric acetate, in either one or two steps.
The maximum yield of the unsymmetrical dialkyl carbonates is 30–35% when based on reacted alcohols, and it is obtained at 200°, a CO pressure of 25–60 atm, and an n-C3H7OH/R′OH ratio≈2.
