실험 절차

A stream 11 essentially containing all the non-reacted phenol, phenyl methyl carbonate and any possible diphenyl carbonate produced, the transesterification catalyst and a fraction of the dimethylcarbonate fed, is extracted from the bottom of the reaction section of column C1 so that the molar ratio, in this stream, between the dimethyl carbonate and the phenol is between 0.5 and 5, normally between 1.0 and 5.0. This fraction usually forms between about 10 and about 60% of the total dimethyl carbonate fed to column C1.
