Title (EN) PROCESS FOR THE PREPARATION OF PHENOLIC COMPOUNDS
(FR) PROCEDE DE PREPARATION DE COMPOSES PHENOLIQUES
Abstract: front page image
(EN)Process for the preparation of hydroxytyrosol and its precursors (3,4- dihydroxyphenyl)-acetic acid C1-10-alkyl esters by hydrogenating in a C1-10-alkanol 3,4- mandelic acid or a 3,4-dihydroxymandelic acid C1-10-alkyl ester in the presence of a hydrogenation metal catalyst and optionally reducing the ester obtained to give hydroxytyrosol.
(FR)L'invention concerne un procédé de préparation de l'hydroxytyrosol et de ses précurseurs C1-10-alkyl esters de l'acide (3,4- dihydroxyphenyl)-acétique par hydrogénation dans un C1-10-alcanol de l'acide 3,4- mandélique ou un C1-10-alkyl ester de l'acide 3,4-dihydroxymandélique en présence d'un catalyseur métallique d'hydrogénation et éventuellement par réduction de l'ester obtenu afin de former l'hydroxytyrosol.
