| Abstract: | The synthesis of polyglycerol was studied.Polyglycerol was synthesized by dehydrate condensation from glycerol in the presence of NaOH.The effects of catalyst dosage,reaction time and reaction temperature on glycerol polymerization were investigated.Tawny nonaglycerol was obtained when 40 g glycerol condensated in the presence of 1.6 g NaOH in 260 ℃ for 210 min. |
