Изобретение относится к способу получения 2-алкил-4-ацил-6-третбутилфенольных соединений имеющих химическую структуру. Производные 2-алкил-4-ацил-6-третбутилфенола получают в реакционной смеси, включающей соответствующий 2-алкил-6-третбутилфенол, соответствующую карбоновую кислоту RСООН и ангидрид трифторуксусной кислоты.The invention relates to a method for producing 2-alkyl-4-acyl-6-tert-butylphenol compounds having a chemical structure. Derivatives of 2-alkyl-4-acyl-6-tert-butylphenol are obtained in a reaction mixture comprising the corresponding 2-alkyl-6-tert-butylphenol, the corresponding carboxylic acid ROOH and trifluoroacetic anhydride.
