Conversion to INA and Processing

The JM process is a rare example of a commercial process in which long-chain branched olefins can be processed using rhodium-catalyzed hydroformylation. It is based on a special rhodium separation process. This enables much of the rhodium to be recovered, which is the basic requirement for any economically viable hydroformylation process based on this metal. Processing under severe conditions is required. This is a basic limitation for the process, as the use of ligands, which play a considerable part in the superiority of rhodium-based processes, is possible - if at all - only with very inexpensive ligands. 

ExxonMobil Process for the Production of Highly Branched, Long-Chain Alcohols 

An example of a cobalt-based hydroformylation process for long-chain, highly branched olefins is a process developed by Exxon to produce IDA from isomer mixtures of the nonene. There are several recently published patents that describe a further development of this process, thus illustrating that continuous development of the older cobalt technology keeps it competitive for selected challenging hydroformylation processes, such as for complex, highly branched, longer chain olefins.
