摘　　要：通过月桂酰氯和甘氨酸合成了N-月桂酰基甘氨酸钠,用元素分析、红外光谱、核磁共振进行了结构表征.结果表明合成产物为目标化合物.并对其表面化学性能和应用性能进行了测试:N-月桂酰基甘氨酸钠溶液在0.50mol·L-1 NaCl浓度下,其临界胶束浓度(Ccmc)为1.118mol·L-1,临界胶束浓度下的表面张力(γcmc)为31.1mN·m-1,具有较高的表面活性.应用性能亦较佳.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. 118 mol·L^-1at c（NaC1）=0.50 mol·L^-1 , and the surface tension （γcmc） is 31.1 mN · m-1. So it has high surface activity. It also has good application prop-erties
