Abstract

L'invention se rapporte à un procédé de préparation de l'aldéhyde protocatéchique ou d'un 3-alcoxy-4-hydroxybenzal-déhyde. Selon l'invention, on fait réagir le pyrocatéchol ou un 2-alcoxyphénol avec l'acide glyoxylique milieu basique aqueux, en présence d'un catalyseur renfermant un ou plusieurs composés choisis parmi l'oxyde d'aluminium, la silice et l'oxyde d'aluminium hydraté, en une quantité qui n'est pas inférieure à 0,01 g pour 1 g du pyrocatechol ou du 2-alcoxyphénol de départ, à une température de 0 à 50 degrés C, puis on oxyde le mélange réactionnel ainsi obtenu, dans un milieu basique aqueux. Applications : fabrication de produits intermédiaires dans l'industrie pharmaceutique ou en parfumerie.
