Synthesis and Properties of Rosin-based Quaternary Ammonium Salt Heterogemini Surfactant
摘要
Abstract
Four rosin-based quaternary ammonium heterogemini surfactants were synthesized from dehydroabietic acid via the reactions of amidation, reduction and quaternarization, which were named N, N, N′, N′-tetramethyl- N-dehydroabietyl-1, 3-propylene diammonium bromide, N,N,N′,N′-tetramethyl-N-dehydroabietyl-1,4-butane diammonium bromide, N,N,N′,N′-tetramethyl-N-dehydroabietyl-1,5-pentane diammonium bromide, and N, N, N′, N′-tetramethyl-N-dehydroabietyl-1, 6-hexane diammonium bromide. The structures of these compounds were confirmed by FT-IR and 1H NMR. The surface activities, e. g. surface tension (γcmc ), critical micelle concentration ( Ccmc ) and Krafft points, ect. . Their antibacterial activities were investigated and analyzed. The results showed that the Ccmc values of the heterogemini surfactants were 3. 32 × 10-5 , 2. 86 × 10-5 , 2. 54 × 10-5 , 2. 28 × 10-5 mol/L, and the γcmc values were 24. 7, 26. 5, 28. 9, 32. 3 mN/m, the Krafft points 12, 17, 20, 23 ℃, respectively. Separating 10 mL water from the turpentine/water emulsion spent 42, 45, 53 and 48 h, respectively. The initial foam heights were 137, 128, 131 and 135 mm, and after 5 minutes, the heights reached 125, 121, 127 and 131 mm, respectively. Through the test, the minimal inhibitory concentration on escherichia coil were 4,<2,<2 and 2 mg/L and the antibacterial activities were superior to the commercial bacteriostatic agent bromogeramine (64 mg/L).关键词
