Glycerol oligomerization in continuous flow reactor
Nicolas Galy,Rémi Nguyen,Philippe Blach,Sophie Sambou,Denis Luart,Christophe Len 한국공업화학회 2017 Journal of Industrial and Engineering Chemistry Vol.51 No.-
Thefirst synthesis of polyglycerol in continuousflow reactor in presence of potassium carbonate ashomogeneous catalyst was reported varying different parameters: temperature,flow and residence time. The different regioisomers of glycerol dimers and glycerol trimmers have been characterized and thedistribution of the different oligomers has been quantified. Further investigations in a cyclic mode,combined with short path distillation, afforded a mixture of predefined glycerol oligomers with adistribution: glycerol dimer (20 wt%), glycerol trimer (21 wt%), glycerol tetramer (16 wt%) and glycerolpentamer (11 wt%).
