Title:
METHOD FOR THE CONTINUOUS PRODUCTION OF AROMATIC CARBONATES
Document Type and Number:
WIPO Patent Application WO2002040439
Kind Code:
A3
Abstract:
The present invention provides a method for making aromatic carbonates. In this method, an aryl alcohol is reacted with a dialkyl carbonate in a reactor (e.g., a distillation column) to produce an arylalkyl carbonate and diaryl carbonate. The total yield of arylalkyl carbonate and diaryl carbonate together is at least 40 %. Also, the selectivity of diaryl carbonate versus diaryl carbonate and arylalkyl carbonate together is preferably at least 25 %.
