METHOD OF SYNTHESIS OF 2-ALKYL-4-ACYL-6-TERT-BUTYLPHENOLIC COMPOUNDS AND THEIR CRYSTALLINE PURIFIED FORMS |
摘要 |
FIELD: organic chemistry and technology. SUBSTANCE: invention relates to method of synthesis of 2-alkyl-4-acyl-6-tert.-butylphenolic compounds of the chemical formula (I): $$$ where B - $$$-saturated nonsubstituted direct $$$-alkylene; Y means group taken from $$$ and -CH=C=$$$ and $$$ is taken from saturated linear or branched alkyl having 1-10 carbon atoms. Derivatives of 2-alkyl-4-acyl-6-tert.-butylphenol are synthesized in reaction mixture involving the corresponding 2-alkyl-6-tert.-butylphenol of the formula (II): $$$, corresponding carboxylic acid: Y-B-COOH and trifluoroacetic acid anhydride. EFFECT: improved method of synthesis. 9 cl
