COMPOSITION FOR WATER TREATMENT FROM SOLID SUSPENDED SUBSTANCES AND OIL PRODUCTS Russian patent published in 2024 - IPC C02F1/54 

FIELD: chemistry.

SUBSTANCE: invention relates to a reagent used in the field of water treatment from suspended mineral substances and oil products, is intended for destruction of stable oil emulsions and suspensions, in particular, production wastes during oil production. Composition for purifying water from solid suspended substances and oil products contains a mixture of long-chain sodium alkylamino phosphonate of structural formula: , where n = 10÷20; R – functional alkylphosphonic groups of formula (CH₂PO₃)₂Na₄, and a short-chain aminophosphonic complexone containing from 2 to 5 functional akylphosphonic groups and water. Short-chain aminophosphonic complexone is selected from sodium salts of methyliminodimethylenephosphonic, nitriletrimethylenephosphonic, ethylenediaminetetramethylenephosphonic, diethylenetriaminepentamethylenephosphonic acids.

EFFECT: increasing the efficiency of water purification from mixtures of mineral substances and petroleum products by increasing the purification rate while simultaneously reducing the consumption of reagents.
