FORMULATION OF ANTI-ICING FLUID OF TYPE 4 Russian patent published in 2019 - IPC C09K3/18 B64D15/06 

FIELD: chemistry.

SUBSTANCE: invention relates to compositions of anti-icing fluids for aircraft ground processing. Anti-icing fluid comprising water, a mixture of diethylene glycol and glycerine or pure glycerine; hydrophobically modified acrylic thickener; surfactant, which is a mixture of polyoxyethylene glycol ethers of synthetic primary higher fatty alcohols of fraction C₁₂-C₁₄; corrosion inhibitor, which is 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; sodium soaps of higher carboxylic acids separated from sap effluents.

EFFECT: invention provides high viscosity and an index of pseudoplasticity at low temperature of crystallisation beginning.
