Carbonylation process

Process for carbonylating an alcohol or reactive derivative thereof, by (a) feeding one or more feed streams to a reaction zone, at least one feed stream containing an alcohol or reactive derivative thereof, and at least one feed stream contains CO, (b) maintaining in the reaction zone a temperature...

Summary:Process for carbonylating an alcohol or reactive derivative thereof, by (a) feeding one or more feed streams to a reaction zone, at least one feed stream containing an alcohol or reactive derivative thereof, and at least one feed stream contains CO, (b) maintaining in the reaction zone a temperature and pressure sufficient to allow an exothermic carbonylation reaction to occur to produce a carboxylic acid or carboxylic acid anhydride, (c) removing one or more product streams containing carboxylic acid or carboxylic acid anhydride from the reaction zone, and (d) transferring heat contained in one or more product streams to a first heat-exchange stream. Heat is transferred from a second heat-exchange stream to a feed stream of step (a) before the feed stream is fed to the reaction zone, and the temperature of the second heat-exchange stream before heat transfer is lower than that of the one or more product streams.
