Synthesis and properties of lauroylamidopropyl betaine with low salt content
摘要
Abstract
Lauroylamidopropyl betaine with low salt content was synthesized from lauric acid, N,N- di-methyl- 1,3- diaminopropane and sodium chloroacetate by two- steps, amidazation and quaternization. The structure and main properties of products were determined by FTIR and 1HNMR. The results showed that the contents of active substance reached 82.00% and NaCl mass fraction decreased significantly. When the active substance solution was 30%, the mass fraction of NaCl was only about 1.79%, and the mass fraction of unre-acted amine was 0.30%. At the same time, the lowest surface tension of solutions was 26.76 mN/m, cmc was 3.65 mmol/L and viscosity was 88.81 mPa·s.关键词
