Abstract

Procédé continu basé sur la conversion de 3-cyclohexène-1-carboxaldéhyde en présence d'un mélange d'alcoolates d'aluminium dont les composantes d'alcool consistent pour moitié en groupes isopropylate et pour moitié en groupes sec.-butylate. On utilise une cascade de réacteurs à agitateurs suivie d'un tube d'écoulement, puis on distille.
