LUBRICATING ADDITIVE TO DIESEL FUELS, WHICH IS FURFURAL ACETALS, AND A FUEL COMPOSITION CONTAINING IT Russian patent published in 2020 - IPC C10L1/18 C10L1/02 C07D307/46

Abstract RU 2736717 C1

FIELD: chemistry.

SUBSTANCE: present invention relates to a lubricant for ester-based diesel fuels, wherein the additive contains furfural acetals obtained by reacting furfural and monoatomic alcohols C₄-C₇ in the presence of a sulpho-cationite catalyst of a macroporous structure, in molar ratio furfural : alcohols C₄-C₇=1:6–10, at temperature range -5–40°C. Invention also relates to a diesel fuel composition which contains a lubricating additive in amount of 5–20 wt% and ignition promoter in amount of up to 0.4 wt%.

EFFECT: technical result of the invention is the development of a lubricating additive to diesel fuels, which is furfural acetals.
