Abstract

Il s'agit d'un procédé continu de fabrication de 3-cyclohexène-1-carboxaldéhyde par réaction d'acroléine avec du butadiène, à des températures et des pressions élevées, dans lequel on arrive à obtenir de bons rendements par réglage entre 1:5 et 1:6 du rapport pondéral entre les substances de départ introduites dans un réacteur à recirculation par unité de temps et le mélange réactionnel recyclé par unité de temps et en prévoyant une réaction ultérieure dans des réacteurs placés en aval.
