OXIDISED AND MALEATED COMPOUNDS AND COMPOSITIONS Russian patent published in 2013 - IPC C09K8/36 C09K8/54 C23F11/12 C23F11/173 

FIELD: chemistry.

SUBSTANCE: invention relates to an oxidised and maleated tall oil composition, as an emulsifier or corrosion inhibitor, containing tall oil having at least two C₁₀-C₂₄ structures, where at least one of the C₁₀-C₂₄ structures is substituted with at least one α,β-unsaturated carboxylic acid or anhydride, wherein the C₁₀-C₂₄ structures are cross-linked by an ether bond, and where the oxidised and maleated tall oil composition has acid number from about 50 mg KOH/g to about 400 mg KOH/g. The invention also relates to the following methods: production of an oxidised and maleated tall oil composition, as an emulsifier or corrosion inhibitor, containing tall oil having at least two C₁₀-C₂₄ structures, where at least one of the C₁₀-C₂₄ structures is substituted with at least one α,β-unsaturated carboxylic acid or anhydride, wherein the C₁₀-C₂₄ structures are cross-linked by an ether bond, and where the oxidised and maleated tall oil composition has an acid number from about 50 mg KOH/g to about 400 mg KOH/g, involving providing tall oil having at least two C₁₀-C₂₄ structures, maleating the tall oil and oxidising the tall oil; to emulsification of a solution, including a step of combining the solution with an effective amount of the oxidised and maleated tall oil composition; to inhibition of corrosion on a metal surface, involving contacting the metal surface with an effective amount of the oxidised and maleated tall oil composition; and to reducing corrosion of a metal surface, involving contacting the metal surface with an effective amount of the oxidised and maleated tall oil composition.

EFFECT: obtaining an oxidised and maleated tall oil composition.
