The invention provides a method for producing a diaryl carbonate by a transesterification reaction between a dialkyl carbonate and an aromatic alcohol in the presence of [t a] the transesterification catalyst over a period of time, wherein the aryl moiety is unsubstituted phenyl and monosubstituted, disubstituted and trisubstituted is selected from a phenyl group, wherein the alkyl moiety is C 2 to C 4 is selected from linear and branched alkyl groups, the catalyst concentration is showing a catalyst gram per gram of aromatic alcohol and dialkyl carbonate [c and displayed as a], the period of the time [t m] and catalyst concentration [c m] is set to a value ranging from a predetermined equilibrium closure during the transesterification reaction of a methyl aryl carbonate and methanol in the dimethyl carbonate and the aromatic alcohol, the product [c a] * t a to a method of at least 1.5 * [c m] * t m other under the same conditions. A diaryl carbonate, a transesterification reaction, an aromatic alcohol, dialkyl carbonate
