Crosslinking of collagen with dicarboxylic acids / F. Scholnick in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. LXXXVII, N° 9 (09/1992)
[article]
Titre : Crosslinking of collagen with dicarboxylic acids Type de document : texte imprimé Auteurs : F. Scholnick, Auteur ; L. L. Liao, Auteur ; Eleanor M. Brown, Auteur ; Stephen H. Feairheller, Auteur Année de publication : 1992 Article en page(s) : p. 333-338 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675.2 Préparation du cuir naturel. Tannage Résumé : We have studied the crosslinking of collagen in sheepskin by treatment with N-hydroxysulfosuccinimide esters of dicarboxylic acids.The acylating agents are prepared from dicarboxylic acids including suberic (C-8), azelaic(C-9) and sebacic(C-10) acids.These agents are extremely soluble in water and react readily with sheepskin,resulting in increases in shrinkage temperatures before chrome tanning.A descrisption of the synthesis of acylating agents and a discussion of the physical properties of the resulting leathers are presented.

Titre : Beneficial use of vegetable tannery biosolids : A proven method of disposal cost reduction Type de document : texte imprimé Auteurs : Wayne H. Billings, Auteur ; Robert J. Kopka, Auteur Année de publication : 1992 Article en page(s) : p. 339-352 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Pickard and Anderson(P&A) of Auburn,New York, successfully sought and obtained permits for the Beneficial Use of Vegetable Tannery Biosolids for two different Pennsylvania tanneries,Gunnison Brothers,Inc. and Wickett and Craig of America.These permits were obtained through the Pennsylvania Department of Envirionmental Resources Bureau of Waste Management(DER-BWM).Presently, the biosolids are being used as a soil supplement in the reclamation of coal strip mined lands in central and north-central Pennsylvania.
During the initial phase of projects,each company was able to reduce its total volume of waste disposed by greater than 50 percent,cutting waste disposal costs by a significant amount.Additional research is planned to determine if other portions of each company's waste can be removed from the waste streams and incoporated into soil supplements.Future research is planned for packaging the biosolids as soil supplements for sale to consumers.Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8285
