| titleOfInvention | Process for the preparation of a diaryl carbonate |
| abstract | The invention relates to a process for the preparation of a diaryl carbonate, which comprises: (i) contacting an aromatic non-hydroxy compound with a carboxylic acid of formula HOC(═O)R1 (I), wherein R1 is a hydrocarbyl group, and with an oxygen containing gas in the presence of a catalyst, resulting in water and an aromatic carboxylic acid ester of formula R2OC(═O)R1 (II), wherein R2 is an aryl group originating from the aromatic non-hydroxy compound; and (ii) contacting the aromatic carboxylic acid ester of formula (II) from step (i) with a dialkyl carbonate of formula R3OC(═O)OR4 (III), wherein R3 and R4 are the same or different and are alkyl groups, in the presence of a catalyst, resulting in a diaryl carbonate of formula R2OC(═O)OR2 (IV) and an alkyl carboxylic acid ester of formula R5OC(═O)R1 (V), wherein R5 is R3 or R4. |
