Hydroformylation of vegetable oils: More than 50 years of technical innovation, successful research, and development

“…Cyclodextrins (CDs) also acted as interfacial additives in the very challenging hydroformylation of triglycerides using a Rh‐catalyst retained in water by TPPTS. Upon stirring of the two‐phase system, CDs supramolecularly interact with one of the triglyceride alkenyl chain to form a transient CD/triglyceride supramolecular complex (1:1 stoichiometry) at the aqueous/organic interface . The amphiphilic CD/triglyceride complexes allowed for a significant increase in the surface area.…”

Hydroaminomethylation of oleochemicals: A comprehensive overview

“…Countless functionalizations of oleochemicals have already been implemented [5]. The carbon-carbon double bonds of fatty acids, fatty esters, and triglycerides have especially been converted into epoxy [6][7][8][9][10][11][12][13], hydroxyl [14][15][16][17][18][19][20][21], formyl [22][23][24][25][26][27], acrylate [28][29][30], or crossmetathesis derivatives [31][32][33], to name only a few. The functionalization of the carbon-carbon double bonds by amino groups is also of great interest.…”

The Pivotal Role of Catalysis in France: Selected Examples of Recent Advances and Future Prospects.

“…Among the research axes, catalytic approaches, including new chemo‐ and biocatalytic systems are developed, including their one‐pot combination under the new concept of hybrid catalysis . Since the program launch year (2012), many results have been obtained, some of which have been now disclosed after a patenting process, with the resultant portfolio of efficiently developed reactions such as the conversion of glycerol to added value products such as glycolic or glyceric acid, including raw glycerol reactivity, as well as conversion to divinylglycol; direct conversion of alcohols to carboxylic acids, as well as to cerides/symmetrical esters; hydroformylation of triglycerides in a self‐emulsifying medium; synthesis of conjugated dienyl derivatives by green bisallylic substitution; decarbonylation of fatty acids; selective polyol dehydration. Another large project in the field of catalyst development for biosourced application is REALCAT, “Advanced high throughput technologies platform for biorefineries catalysts design”, which consists of a high‐throughput platform, unique in the world, devoted to innovation in heterogeneous, homogeneous, bio‐, and hybrid catalysis.…”
