PHASE-SELECTIVE GEL FORMATION WITH ALKYLATED AROMATIC ACIDS

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a process, comprising mixing an aromatic acid with a mixture, comprising a first liquid and a second liquid, thereby causing the formation of organogel, comprising aromatic acid and a first liquid. Wherein the aromatic acid has the formula ; ;where R₁, R₃ and R₅ are hydrogen,R₂ represents-X₁-Rc₁,R₄ is -COOH or -X_2-Rc₂, X₁,X₂ represent -NH-C(O)-, Rc₁ and Rc₂ represent branched unsubstituted alkyl group or a linear unsubstituted group of the formula -(CH₂)_nCH₃, wheren is an integer which is at least 15; or aromatic acid has the formula: ; ,;where R₁, R₂,R₁',R₂' represents a COOH group, and R_d represents a bifunctional group, which bridges the aromatic acid group. The invention also relates to a method of extraction and a method of processing organic pollution, comprising introducing an aromatic acid in crude oil pollution.;EFFECT: improved properties of compounds.;12 cl, 5 ex
