Abstract

On produit avec efficacité du triméthylolpropane de grande pureté en mélangeant le produit de réaction d'aldol de formaldéhyde et n-butyraldehyde avec au moins environ 20 % en poids d'un alcool inférieur avant l'hydrogénation afin de permettre la récupération d'un produit de grande pureté par simple distillation. Dans un mode moins performant, on peut ajouter l'alcool après l'hydrogénation, ce qui n'entraîne qu'une très légère amélioration des procédés antérieurs.
