Preparation of liquid polyols from d-(+)-glucose (Glc) and its derivative, methyl-α-d-glucoside (m-Glc), has been studied. Direct reaction of ε-caprolactone (CL) with Glc (CL : Glc = 2 : 1–5 : 1 in weight ratio) at 150°C using tin(II) 2-ethyl hexanoate (SnEht2) (series A), in which melted Glc was suspended in CL, resulted in a dark-brown coloration of the reactants. The reaction was accompanied by formation of high molecular weight resins, a pH drop, production of water, and a considerable… CONTINUE READING
