Abstract

Procédé pour préparer du dibenzylidènesorbitol par déshydrocondensation d'une mole de sorbitol avec deux moles de benzaldéhyde en présence d'un catalyseur acide. On effectue la réaction en deux stades, le premier stade de réaction consistant à faire réagir les composés de départ en chauffant à une température de 50 à 70 degrés C, on passe du premier stade de réaction au second stade de réaction par addition d'eau et d'une quantité additionnelle d'un catalyseur acide lorsque la conversion du sorbitol en dibenzylidènesorbitol atteint 10 à 40 %, et le second stade de réaction consiste à faire réagir le mélange en suspension à la température ordinaire dans 2,5 parties en poids ou plus par partie en poids de sorbitol d'un milieu réactionnel aqueux et on recueille le dibenzylidènesorbitol formé sous forme d'une suspension aqueuse
