PROCESS FOR PREPARING AROMATIC CARBONATES

摘要

The present invention, which relates to a process for preparing aromatic carbonates, provides a process for preparing diphenylcarbonate comprising the steps of preparing methylphenylcarbonate by gas phase reacting or liquid phase reacting dimethylcarbonate with phenol under titanium-silica catalyst in which titanium is supported on silica support and liquid phase reacting the prepared methylphenylcarbonate under titanium-silica catalyst in which titanium is supported on silica support, a process for preparing methylphenylcarbonate by liquid phase reacting dimethylcarbonate with phenol using molybdenum-activated carbon catalyst in which molybdenum is supported on activated carbon, and a process for preparing methylphenylcarbonate by gas phase reacting dimethylcarbonate with phenol using heterogeneous solid catalyst.
