Abstract

La présente invention est relative à un procédé de préparation d'acétals cycliques d'aldéhydes aliphatiques. Le procédé consiste à faire réagir des aldéhydes contenant 2 à 16 atomes de carbone à des températures de -20 à + 50 degrés C en présence de gel de silice et en l'absence d'eau. Le procédé est simple et économique tout en permettant une cyclisation avec une conversion élevée.
