Title
(EN) PROCESS FOR THE PREPARATION OF 2-ALKYL-4-ACYL-6-$i(TERT)-BUTYLPHENOL COMPOUNDS
(FR) PROCEDE DE PREPARATION DE COMPOSES DE 2-ALKYLE-4-ACYLE-6-$i(TERT)-BUTYLPHENOL
Abstract
(EN) The subject invention relates to a process for the preparation of 2-alkyl-4-acyl-6-$i(tert)-butylphenol compound having chemical structure (1), wherein -R is an aliphatic group having a terminally unsaturated moiety selected from -C=CH and -CH=C=CH2, and R' is selected from saturated, straight, branched or cyclic alkyl having from 1 to about 10 carbon atoms; the 2-alkyl-4-acyl-6-$i(tert)-butylphenol compound being produced in a reaction mixture comprising the corresponding 2-alkyl-6-$i(tert)-butylphenol (2), the corresponding carboxylic acid: RCOOH, and trifluoroacetic anhydride.
(FR) L'invention se rapporte à un procédé de préparation d'un composé de 2-alkyle-4-acyle-6-$i(tert)-butylphénol de la structure chimique (1), où -R représente un groupe aliphatique comprenant une fraction à terminaison insaturée choisie à partir de -C=CH et de -CH=C=CH2, et R' est choisi à partir d'un alkyle saturé, droit, ramifié ou cyclique comprenant de 1 à 10 atomes de carbone environ; le composé de 2-alkyle-4-acyle-6-$i(tert)-butylphénol étant produit dans un mélange réactif comprenant le 2-alkyle-6-$i(tert)-butylphénol correspondant (2), l'acide carboxylique correspondant: RCOOH, et un anhydride trifluoracétique.
