Abstract: front page image
(DE)Die vorliegende Erfindung beschreibt ein Verfahren zur Herstellung eines hydrophoben Stärkederivats durch Veresterung alkoholischer Funktionen mit organischen Säureanhydriden in wässrigen Salzlösungen. Die erhaltenen hydrophoben Stärkederivate verbessern z.B. die Wasserstabilität von Papieren.
(EN)The present invention relates to a process for preparing a hydrophobic starch derivative by esterifying alcoholic functions with organic acid anhydrides in aqueous salt solutions. The resulting hydrophobic starch derivatives improve, for example, the water stability of papers.
(FR)La présente invention concerne un procédé de préparation d'un dérivé d'amidon hydrophobe par estérification de fonctions alcool avec des anhydres d'acides organiques dans des solutions salines aqueuses. Les dérivés d'amidon hydrophobes obtenus permettent d'améliorer par ex. la stabilité de papiers dans l'eau.
