CYCLIC ORTHO-ESTER FUEL ADDITIVES Russian patent published in 2018 - IPC C10G33/04 C07D317/22 

FIELD: chemistry.

SUBSTANCE: invention relates to liquid hydrocarbons containing a dehydrating icing inhibitor selected from formula I, salts or mixtures thereof, where: R¹ is selected from an unsubstituted, branched or linear C₁-C₆alkyl or ether group; R² is independently selected from unsubstituted, linear or branched C₁-C₇-alkyl; Y is independently selected and is unsubstituted alkyl; y is an integer from 1 to 3. Liquid hydrocarbon is aviation fuel, gasoline, diesel or heating oil. Invention also relates to a method for inhibiting the formation of ice crystals in a liquid hydrocarbon and the use of compound III, wherein: R¹ is selected from an unsubstituted, branched or linear C₁-C₆alkyl or ether group; R² is selected from unsubstituted, linear or branched C₁-C₇-alkyl; R⁵ and R⁷ are hydrogen; R⁶ and R⁸ are methyl, and where R⁶ and R⁸ can be in the cis or trans position relative to each other. .

EFFECT: invention can be used as a dehydrating icing inhibitor.
