SURFACE-ACTIVE PREPARATION FOR LOCALISATION OF HYDROCARBON POLLUTION Russian patent published in 2021 - IPC C09K3/32 E02B15/04 

FIELD: biotechnology.

SUBSTANCE: invention relates to biotechnology, in particular, to the field of environmental protection, and can be used to concentrate and prevent a hydrocarbon spill from spreading on the water surface. The surface-active preparation for localisation of hydrocarbon pollution comprises an oxyethylated cationic surface-active agent (surfactant) constituting a mixture of oxyethylated quaternary nitrogen-containing bases (NR)₄ (CH ₂CH₂O)nOH, wherein the length of the radical R=C₁₀ to C₁₄, the average degree of oxyethylation n=2 to 6, and oxyethylated alcohols R(CH₂CH ₂O)nOH, wherein the length of the radical R=C₁₀ to C ₁₂, the average degree of oxyethylation n=6 to 8. The preparation also comprises a mixture of organic solvents containing butyl glycol, diethyl ether and heptane in specified quantities.

EFFECT: invention provides a possibility of reducing the time for elimination of hydrocarbon spills, increasing the efficiency of removing hydrocarbon spills, and facilitating the process of eliminating pollution.
