Abstract
L'invention concerne la production d'acide sébacique à partir d'acide adipique. Selon l'invention, on hémi-estérifie l'acide adipique avec du méthanol pour produire de l'adipate de monométhyle, dont on effectue la condensation électrolytique dans une solution de méthanol contenant un sel d'un métal alcalin de l'adipate de monométhyle pour donner une solution électrolytique contenant du sébaçate de diméthyle, qui est traitée à l'eau et par échange d'anions ou échange de cations et échange d'anions pour enlever l'adipate de monométhyle et son sel d'un métal alcalin de la solution électrolytique, on sépare le sébaçate de diméthyle et on l'hydrolyse pour donner de l'acide sébacique. On emploie un réservoir de dissolution 1, des colonnes de résine échangeuse d'ions 2 et 3, des colonnes de distillation 4,5 et 6 et une purge 7. L'invention s'applique notamment à la production industrielle de l'acide sébacique.
