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, theminimal inhibitory concentration on escherichia coil were 4,<2,<2 and 2mg/L and the antibacterial activities were superior to the commercial bacteriostatic agent bromogeramine (64 mg/L).%以脱氢枞酸为原料,经酰胺化、还原、季铵化反应制备了N,N,N′,N′-四甲基-N-去氢枞基-N′-十二烷基-二溴化-1,3-丙二铵(V3)、N,N,N′,N′-四甲基-N-去氢枞基-N′-十二烷基-二溴化-1,4-丁二铵(V4)、N,N,N′,N′-四甲基-N-去氢枞基-N′-十二烷基-二溴化-1,5-戊二铵(V5)及N,N,N′,N′-四甲基-N-去氢枞基-N′-十二烷基-二溴化-1,6-己二铵(V6)等4种松香基季铵盐型杂双子表面活性剂。
