| Résumé : |
In the presence of an acid-binding agent loaded on alumina, 3-dehydroabietylamino-2-hydroxypropyl trimethyl ammonium chloride (DHAHPTMA) was synthesized with dehydroabietylamine (DHA) and 3-chloro-2-hydroxypropyl trimethyl ammonium chloride (CTA) as starting material. The structure of DHAHPTMA was characterized by FT-IR and 1H-NMR, and the content of DHAHPTMA in product was determined by Ion Chromatography (IC). The antibacterial activity of DHAHPTMA was evaluated according to its minimum inhibitory concentrations (MICs) against Staphylococcus aureus (S. aureus), Staphylococcus epidermidis (S. epidermidis), gas bacillus, Klebsiella pneumoniae, Escherichia coli (E. coli), Pseusomonas aeruginosa (P. aeruginosa) and Salmonella. Results of IC showed that the mass content of DHAHPTMA in the product was higher than 97%. The experimental results also indicated that the MICs of DHAHPTMA against S. aureus, S. epidermidis and E. coli were lower than that of Bromo-Geramium against theses bacteria. |
