ABSTRACT:
An apparatus for preparing a dialkyl carbonate comprises means for reacting an alkanol, oxygen, carbon monoxide, and a catalyst to form a mixture comprising a dialkyl carbonate, an alkyl chloroformate, hydrochloric acid, water, carbon dioxide, and carbon monoxide; means for separating from the mixture a gaseous fraction comprising carbon monoxide and alkyl chloroformate; and means for removing alkyl chloroformate from the gaseous fraction.
