Hydroformylation or Oxo Synthesis/Process

Understand Catalyst Activity


Hydroformylation, or oxo synthesis/process, is important for the production of olefins to aldehydes and aldehydes from alkenes. Hydroformylation reactions are performed at high pressure and can be challenging to sample due to the extreme reaction conditions, as well as the toxic, flammable, and reactive raw materials and reagents.

In a hydroformylation, the catalyst is typically an expensive part of the process. Air oxidation of the active species is the first step in losing the valuable metal catalyst. In some cases, converting the catalyst back to active form can be accomplished, but at a cost to production and resources.

The ability to monitor the catalyst for activity and selectivity is key. Real-time in situ FTIR spectroscopy (ReactIR) enables the reaction to be followed without the need for sampling. It provides in-depth knowledge about the catalyst by monitoring the metal carbonyl bands in the 2200-1900cm-1 region where few other species absorb. The H2/CO ratio also affects the amount of active catalyst. Investigating different gas ratios and environments provides the ability to gain insight into the catalyst mechanism and selectivity. Catalyst intermediates can also be observed to elucidate their impact on product yield and purity.

在高压下运行反应的需求正在日益增多。 由于压力化学的特性,反应物质通常由多相组成,即液态/气态,甚至液态/固态/气态。 因此,这种反应不但受一般参数的控制,如反应物质的温度或反应物的浓度,而且还受其他一些参数的控制,如气体供给、催化剂类型、催化剂浓度、混合,以及后续的传质等。实际上,压力化学的挑战性...
