摘要：Nine different hydrogenated cardanol-based quaternary ammonium compounds including one conventional single-tale single-head surfactant, one bicephalic single-tale double-head surfactant, and seven asymmetric Gemini surfactants were synthetized using a simple process with high yields. Their structures were characterized using H-1 NMR, C-13 NMR, and high-resolution mass spectral studies. Their surface active properties were evaluated by the wilhelmy plate method at 25 degrees C and physical parameters like CMC, gamma(CMC), pi(CMC), C-20, tau(CMC), and A(min) were calculated. The Krafft temperature values of C-BP-1, C-BP-4, and C-BP-6 are lower than 0 degrees C, suggesting high-potential industrial application. All synthesized compounds but C-BP-F exhibit great antimicrobial ability against Gram-positive bacteria (S. aureus [ATCC 25923] and C. glutamicum [ATCC 13032]) while inadequate antimicrobial ability against Gram negative strains (E. coli [ATCC 25922] and P. aeruginosa [ATCC 27853]).
