Synthesis and characterization ofα-{ 3-[2-hydroxy-3-(N-methyl-N-hydroxy-ethylamino)propoxy]propyl}-ω-butylpolydimethylsiloxanes

α-{3-[2-hydroxy-3-(N-methyl-N-hydroxyethylamino)propoxy]propyl}-α-butylpolydimethylsiloxanes III with various molecu-lar weights were prepared by epoxy addition ofα-[3-(2,3-epoxy-propoxy)propyl]-α-butylpolydimethylsiloxanesⅡand N-methylmonoethanolamine.At each step,the outcome compounds were characterized through FT-IR and NMR spectra,the results showed that each step was successfully carried out and objective products were achieved.

(2-羟基-3-烯丙氧基)丙基二乙醇胺基叔胺的合成工艺研究

以二乙醇胺和烯丙基缩水甘油醚为原料合成标题化合物(AGE-DEA)。考察了原料的物质的量比、反应温度和反应时间等工艺条件对反应的影响,确定了最适宜的工艺条件:n(二乙醇胺):n(烯丙基缩水甘油醚)=1.00:1.05,反应温度为55℃,反应时间为4h,在此优化合成工艺条件下,收率达99.41%。产物用FT-IR和1 H-NMR谱图进行了表征。该方法具有工艺条件温和、操作简单、产率高等优点,为产品的工业化及其应用研究奠定了基础。
