| Abstract: | Sodium N-lauroyl glycine was synthesized with glycine and lauroyl chloride acylchloride as raw materials.The structure of the target product was characterized by means of Elementary Analysis,IR and 1 HNMR.The results show that the target product is prepared.Surface chemical properties and application performances of sodium N-lauroyl glycine were studied.The results show that the critical micelle concentration(ccmc)of sodium N-lauroyl glycine is 1.118mol·L-1at c(NaCl)=0.50mol·L-1,and the surface tension(γcmc)is 31.1mN·m-1.So it has high surface activity.It also has good application properties. |
