  • Hydroformylation of triglycerides in a self-emulsifying medium
    Patent number: 9556402
    Abstract: The invention relates to a method for the hydroformnylation of triglycerides by homogeneous catalysis in the presence of at least one substituted cyclodextrin, said method comprising a step a) of combining, under agitation, at least one catalyst, waiter, at least one unsaturated triglyceride and said substituted cyclodextrin, in the presence of gaseous hydrogen and carbon monoxide, said step being carried out in reactive conditions allowing the formation of an emulsion during the agitation and a decanting of the products once the agitation has stopped.
