阳离子表面活性单体DMOAB的制备及性能
Preparation and properties of cationic surface-active monomer DMOAB
摘要
Abstract
Taking N,N'-Dimethyl-1,3-propyldiamine and octadecyl bromide as materials,a novel cationic surface-active monomer,dimethyl octadecylalkyl (3-acrylamidopropyl) ammonium bromide (DMOAB) was successfully synthesized using acryloyl chloride.The structure of DMOAB was characterized by FT-IR and 1 HNMR,and the thermal stability of DMOAB was studied by thermogravimettic analysis.Then,the critical micelle concentration (CMC) values of DMOAB,octadecyl trimethyl ammonium chloride (OTAC) and DMOAB/OTAC mixture were measured respectively using molar conductivity method.It is found that DMOAB exhibited pronounced thermal stability.The CMC values of DMOAB and OTAC are 0.25 mmol · L-1and 0.33 mmol · L-1 respectively.The CMC values of DMOAB/OTAC mixture were 0.26 mmol · L-1and 0.31 mmol · L-1 when the ratio of nDMOA to nOTAc is 2 ∶ 1 and 1 ∶ 2 respectively.The results showed that the CMC value of DMOAB/OTAC mixture is between DMOAB and OTAC.关键词
