Abstract

Ces nouvelles substances répondent à la formule I ci-après. Pour les préparer, on fait réagir, en présence de solvants organiques non polaires, des 2,6-diméthylphénolates de formule Il avec un mono- ou polyacétal de formule III. Ces composés sont des substances de départ intéressantes pour la fabrication de colorants alimentaires.These new substances correspond to formula I below. To prepare them, 2,6-dimethylphenolates of formula II are reacted in the presence of nonpolar organic solvents with a mono- or polyacetal of formula III. These compounds are valuable starting substances for the manufacture of food colors.
