N,N′-乙撑双[乙基十二烷基对苯磺酸(钠)溴化铵]的合成与性能

SYNTHESIS AND PROPERTIES OF N , N′-ETHYLIDENE-DI [ETHYL DODECYL BENZENESULFONIC ACID (SODIUM) AMMONIUM BROMIDE]

以无水对氨基苯磺酸、1,2-二溴乙烷、溴代十二烷为主要原料合成了N,N′-乙撑双[乙基十二烷基对苯磺酸(钠)溴化铵](HYZ)。采用红外光谱和核磁共振氢谱测试技术对目标产物结构进行了表征。该目标产物的临界胶束浓度(cmc)为5.0×10-4 mol/L,γcmc为23.5mN/m。HYZ与阴离子型表面活性剂SDS和阳离子表面活性剂DTAB复配均可产生良好的协同效应。

N, N＇-ethylidenediEethyl dodecyl benzenesulfonic acid （sodium） ammonium bromidewas synthesized by using sulfanilic acid, 1,2-dibromoethane and 1-bromododecane as main materials. IR and 1 H NMR were applied to make primary characterization for the target resultant. The cmc value of aqueous solution of HYZ reached 5.0× 10-4 mol/L, the γcmc of the product reached 23.5 mN/m. The target product showed a synergic effect when blended with SDS and DTAB respectively.
