FIELD: chemistry.
SUBSTANCE: invention relates to an improved catalytic conversion of ketoacids, including to methods of increasing the molecular weight of ketoacids, comprising a stage of preparation of the reaction mixture in the reactor, containing, at least, one ketoacid, water and a base. Then, a base-catalyzed condensation reaction is carried out in the reaction mixture at a temperature of, at least, 65°C. The invention also relates to a method of producing hydrocarbons with high yield, involving astage of increasing the molecular weight of ketoacid, a stage of hydrodeoxygenating this reaction product, and also optionally a stage of isomerization.
EFFECT: high molecular weight compounds produced by the method of the present invention are suitable for use as components of fuels and base oil or chemicals, or as raw materials for their production.
