| Résumé : |
In this work, a triazine tanning agent of 4-((4,6-dichloro-1,3,5-triazin-2-yl)amino) benzenesulfonic acid (SAT) was prepared with cyanuric chloride and sodium p-aminobenzene sulfonate, its structure was confirmed by FTIR spectroscopy, and its tanning property was investigated. The results indicate that SAT can raise the Ts of tanned skin to around 75°C at the optimised dosage of 3%. The stability of tanned leather was tested by washing with aqueous solution of 10w% urea, lOw% NaCI and 14 acetone. The results of washing show that the tanned leather of SAT has excellent stability and there are stable covalent bond interactions between SAT and collagen fibres. Based on the results of washing and the structure characteristics of SAT, a tanning mechanism of SAT was given in which the second Cl and the third CI on the triazine ring can both react with collagen fibres under mild tanning conditions of 35°C to 45°C. |
