Abstract:
Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Multimetallcyanidverbindungen durch Umsetzung der wässrigen Lösung eines Metallsalzes a) mit der wässrigen Lösung eines Hexacyanometallatverbindung b), dadurch gekennzeichnet, dass die Mischung der Lösungen a) und b) auf der Oberfläche eines rotierenden Körpers A zu einem äußeren Bereich der Oberfläche des rotierenden Körpers A fließt und von dort abgeschleudert wird.
Abstract:
The present invention relates to a process for the preparation of nanoparticulate zinc oxide in the form of aqueous suspensions or in the form of pulverulent solid. Furthermore, the invention relates to the use of zinc oxide particles and suspensions prepared in this way in cosmetic sunscreen preparations, as stabilizer in plastics, in paints, in coatings and as antimicrobial active ingredient.
Abstract:
Die vorliegende Erfindung betrifft Verfahren zur Herstellung von oberflächenmodifizierten nanopartikulären Teilchen mindestens eines Metalloxids, Metallhydroxids und/oder Metalloxidhydroxids sowie von wässrigen Suspensionen dieser Teilchen. Weiterhin betrifft die Erfindung die nach diesen Verfahren erhältlichen oberflächenmodifizierten nanopartikulären Teilchen mindestens eines Metalloxids, Metallhydroxids und/oder Metalloxidhydroxids und wässrigen Suspensionen dieser Teilchen sowie ihre Verwendung für kosmetische Sonnenschutz-Zubereitungen, als Stabilisator in Kunststoffen und als antimikrobieller Wirkstoff.
Abstract:
The present invention relates to methods for the production of surface-modified, nanoparticulate particles of at least one metal oxide, metal hydroxide and/or metal oxyhydroxide and of aqueous suspensions of said particles. The invention also relates to the surface-modified, nanoparticulate particles of at least one metal oxide, metal hydroxide and/or metal oxyhydroxide and to the aqueous suspensions of said particles which can be obtained by these methods and their use for cosmetic sunscreen preparations, as stabilisers in plastics and as active antimicrobial active substance.
Abstract:
The invention relates to a method for producing multimetal cyanide compounds by reacting the aqueous solution of a metal salt a) with the aqueous solution of a hexacyanometallate compound b), characterized in that the mixture of solutions a) and b) on the surface of a rotating body A flows to an outer region of the surface of the rotating body A and is centrifuged from there.
