| abstract |
The present invention relates to catalytic conversion of ketoacids, including methods for increasing the molecular weight of ketoacids, the method comprising the steps of providing in a reactor a raw material comprising at least one ketoacid. The raw material is then subjected to one or more C-C-coupling reaction(s) in the presence of an ion exchange resin catalyst to produce at least one ketocid dimer, the method further comprising providing steps of providing in a reactor a feedstock comprising the at least one ketoacid dimer and subjecting the feedstock to one or more C-C-coupling reaction(s) at a temperature of at least 200 °C. |
