Abstract

L'invention concerne un procédé pour préparer des dialdéhydes saturés et insaturés. On prépare des alpha , omega -dialdéhydes saturés et insaturés par réduction catalytique de mono-ozonides de cyclo-oléfines polyinsaturées correspondantes. L'invention s'applique en particulier à la préparation industrielle de dialdéhydes utiles comme intermédiaires de synthèse.
