Titre : Affinity for collagen of chromium complexes separated from masked chrome solutions Type de document : texte imprimé Auteurs : K. Takenouchi, Auteur ; K. Kondo, Auteur ; F. Nakamura, Auteur Année de publication : 1992 Article en page(s) : p. 201-204 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : A hexaaquochromium solution was masked with formate, acetate, and oxalate. The masked chromium complexes were separated by ion exchange chromatography. Hide powder was tanned with the masked chromium complexes. The affinity of the masked chromium complexes for collagen varied with each individual complex. Among various kinds of masked chromium complexes, formatochromium complexes with a charge corresponding to +3 had the highest affinity for collagen at high pH and formatochromium complexes with a charge corresponding to +2 were second in affinity. Acetochromium complexes with a charge corresponding to +3 followed these complexes. Noncationic acetate-and oxalato- chromium complexes had low affinity.

Titre : Changes in the chromium complex composition of masked chrome solutions during tannage and affinity of various chromium complexes for collagen Type de document : texte imprimé Auteurs : K. Takenouchi, Auteur ; K. Kondo, Auteur ; F. Nakamura, Auteur Année de publication : 1991 Article en page(s) : p. 190-196 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : Masked chromium solutions contain a great variety of different complexes which are able to combine selectively with collagen. The changes in the composition of such solutions has been investigated by ion-exchange chromatography. Amongst the formato and acetatochromium complexes, complexes with charges corresponding to +2 and +3 had high affinity for collagen at high pH. Compared with the acetatochromium complexes, formatochromium complexes had considerably higher affinity. Oxalatochromium complexes corresponding to monooxalatochromium had affinities similar to that of the acetatochromium complexes. Anionic acetato and oxalatochromate complexes had very low affinity.

Titre : Effect of masked chromium complexes on thermal stability of collagen Type de document : texte imprimé Auteurs : K. Takenouchi, Auteur ; K. Kondo, Auteur ; F. Nakamura, Auteur Année de publication : 1995 Article en page(s) : p. 188-194 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Hide power was tanned with various kinds of masked chromium chloride solutions and components separated from the masked chrome solutions. The thermal stability of the tanned hide powders was studied by DSC. The thermal stability varied with the kind and amount of chromium complexes fixed by hide powder. Formato and actetatochromium complexes with charges corresponding to + 2 and + 3 had a much greater effect on the thermal stability. Cationic oxalatochromium complexes also had a considerable effect, but anionic oxalatochromate complexes had little effect.
