Definitions
- the present invention is included in the area of the preparation of new catalysts for the fixation of carbon dioxide.
- CO2 is considered as a renewable raw material that has advantages over methane as a source of industrial compounds of a carbon atom.
- processes that consume atmospheric CO2 can help to comply with the Kyoto agreements regarding climate change, contributing to offset CO2 emissions.
- a reaction that has been described in the literature is the insertion of CO2 into epoxides to give cyclic carbonates (equation 1).
- the precedents so far have used chromium and cobalt complexes with "exit" ligands (N, N'-salicylaldehyde-ethylene diimine) and chromium phthalocyanines, in which none of the catalysts described are reusable.
- Carbonates may have applications as gasoline additives to improve the Octane Index, as alternative industrial solvents to volatile organic solvents and as starting reagents in alkylation and caboxyalkylation reactions in substitution of halogenated compounds.
- the present invention solves the problem of the recovery of the catalysts, which due to the dilution in which the reaction mixture is in the known processes for its recovery are very expensive, and on the other hand it achieves Obtain carbonates, useful in multiple applications as noted above.
- the present invention relates first to the use of a catalytic composition comprising:
- first component that is at least one compound of one or more metals of groups 3A, 4A, 5A, 6A, 7A, 8, IB, 2B, 3B, 4B, and - a second component selected from

- said basic nucleophilic agent is a base selected from tertiary amines, alkali cation acetates, alkaline earth cation acetates, basic carbonates and basic solids.
- Said basic nucleophilic agent has the function of adapting the metal complex to the ionic liquid.
