Abstract
The present invention relates to catalytic conversion of ketoacids, including methods for increasing the molecular weight of ketoacids. The method can include providing in a reactor a raw material having 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 can include providing in a reactor a feedstock having 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.
