On fait réagir les alcools primaires aliphatiques avec une substance glucidique, en particulier le glucose, en présence d'un catalyseur acide selon un procédé amélioré de synthèse directe en plusieurs phases successives précises, se terminant obligatoirement par le blanchiment, de manière à obtenir des glucosides particulièrement clairs et stables en milieu alcalin. Ledit procédé peut être appliqué aussi bien en laboratoire qu'à l'échelle industrielle. The aliphatic primary alcohols are made to react with a glycose, in particular glucose, in the presence of an acid catalyst according to a process following given steps in such a manner that, in improved direct synthesis and after a subsequent necessary bleaching stage, particularly light-coloured and alkali-fast alkylglycosides are obtained. Said process can be carried out at laboratory level as well as on an industrial production scale.
