摘要:
本文以玉米淀粉为原料,烷基缩水甘油醚(AGE)为疏水化试剂,氢氧化钠作催化剂,水为溶剂,在较温和反应条件下合成了2-羟基-3-烷氧基丙基淀粉(AHPS)。考察了反应时间、反应温度对取代度和反应效率的影响,确定了最佳反应温度为75℃,最佳反应时间为5 h。用IR、1HNMR对产物结构进行了表征。

Abstract: 2-Hydroxy-3-alkoxypropyl starches (AHPS) were synthesized by an environmentally-friendly process using alkyl glycidyl ether (AGE) as hydrophobic reagent, water as solvent and sodium hy-droxide as catalyst. Effects of reaction time and reaction temperature on molar substitution degree and react efficiency were studied. The optimized reaction time is 5 h and the optimized reaction temperature is 75˚C. IR and 1HNMR were used to analyze the structure of modified products.
