FORMULATION OF ANTI-ICING FLUID OF TYPE 1 Russian patent published in 2019 - IPC C09K3/18 B64D15/06 

FIELD: aviation.

SUBSTANCE: present invention relates to compositions of anti-icing fluids for aircraft surface treatment. Anti-icing fluid comprises an aqueous solution of monoethylene glycol and glycerol, a surfactant in form of a mixture of isomers of oxyethylated alkylphenols based on propylene trimers, a corrosion inhibitor, in form of a mixture of methanol, secondary fatty alcohols and ketones of fraction C₆-C₉, which is a product of the process of oxidising a fraction of n-alkanes C₆-C₉ aqueous solution of hydrogen peroxide on encapsulated titanium silicalite, and a pH regulator of sodium hydrophosphate.

EFFECT: invention reduces corrosion activity, high viscosity while maintaining low crystallisation start temperature.
