Utilization of CO2 as a solvent

Carbon dioxide can be a good alternative to organic solvents, often toxics and harmful for the environment.
We are currently interested in using the carbon dioxide, in supercritical or liquid phase, as a solvent in catalysed processes.

We are studying mainly the following reactions:

- Obtention of aldehydes by hydroformylation of alkenes.

The most efficient and less contaminant way to obtain aldehydes is by reaction of one olefin, carbon monoxide and hydrogen catalysed with a transition metal complex. In this area we have developed a series of catalyst adapted to be used in supercritical carbon dioxide. You can find more information in the following papers:

- Obtention of acids through carbonilation of alkenes.

The reaction of an olefin with water or an alcohol leads to the carboxilic acids or the esters with the maximal atom economy.

You can find information about the catalytic systems that we have developped in the following publications:

- Obtention of poliketones from alkenes and carbon monoxide.

Poliketones are functionalised polymers with potential applications as thermoplastics. We have prepared a series of palladium catalysts for this reaction.
