Title (DE) VERFAHREN ZUR KONTINUIERLICHEN HERSTELLUNG VON PARTIALGLYCERIDSULFATEN
(EN) PROCESS FOR THE CONTINUOUS PRODUCTION OF PARTIAL GLYCERIDE SULPHATES
(FR) PROCEDE DE PRODUCTION EN CONTINU DE SULFATES DE GLYCERIDES PARTIELS
Abstract:
(DE) Partialglyceridsulfate können kontinuierlich hergestellt werden, indem man technische Partialglyceride kontinuierlich mit gasförmigem Schwefeltrioxid umsetzt, die sauren Sulfierprodukte einer Alterung unterwirft und anschließend mit wäßrigen Basen in Gegenwart eines Puffers neutralisiert.
(EN) Partial glyceride sulphates can be continuously produced if technical partial glycerides are continuously reacted with gaseous sulphur trioxide, the acid sulphonation products are subjected to aging and then neutralised with aqueous bases in the presence of a buffer.
(FR) On peut produire en continu des sulfates de glycérides partiels en faisant réagir en continu des glycérides partiels techniques avec de l'anhydride sulfurique gazeux, en soumettant les produits acides de la sulfonation à un processus de vieillissement, puis en les neutralisant avec des bases aqueuses en présence d'un tampon.
