摘要
描述了2,5-二(三氟甲基)-3,6-二氧杂-全氟-1-壬酰胺基丙基(2-亚硫酸)乙基二甲基铵的制备和应用。采用2,5-二(三氟甲基)-3,6-二氧杂-全氟-1-壬酰氟与N,N-二乙基-1,3-丙二胺在～50℃进行酰胺化反应,再与亚硫酸乙二醇双酯在105～115℃进行季铵化反应,得到目标产品。该产品是一种性能优异的氟表面活性剂,质量分数0.1%的水溶液表面张力为16.4mN/m。可广泛应用在化妆品、油墨、胶粘剂、造纸、涂料、消防、清洗等方面,降低溶液的表面张力,提高体系的性能,效果显著。
The preparation and application of 2,5-bis (trifluoromethyl)-3,6-dioxane-hexafluoro-1-nonanoylamidopropy (2-sulfurous acid) dimethyl ammonium were described. 2,5-bis (trifluoromethyl)-3,6-dioxane-hexafluoro-1-fluorononanoyl was amidated by n,n-diethyl-1,3-propyldiamine at 50 ℃,and quaterised by sulfurous acid ethylene glycol ester at 105～115 ℃. The product was a good fluorine surface active agent,and the surface tension of water solution with 0.1% mass fraction was 16.4 mN/m. The product could be widely used in such aspects as cosmetic,printing ink,stickiness,paper making,dope,fire control and cleaning,reduce the surface tension of solution,and greatly improve the system performance.
