An innovative and eco-friendly one-pot synthesis of bio-based polyurethanes is proposed via the epoxy-ring opening of epoxidized soybean oil (ESO) with methanol, followed by the reaction of methoxy bio-polyols intermediates with 2,6-tolyl-diisocyanate (TDI). Both synthetic steps, methanolysis and polyurethane linkage formation, are promoted by a unique catalyst, molybdenum(VI) dichloride dioxide (MoCl2O2), which makes this procedure an efficient, cost-effective, and environmentally safer method amenable to industrial scale-up.
通过环氧大豆油(ESO)与甲醇的环氧化反应,以及生物多元醇中间体与2,6-甲苯二异氰酸酯(TDI)的反应,提出了一种创新且环保的生物基聚氨酯单罐合成方法。甲醇解和聚氨酯连接形成这两个合成步骤均由一种独特的催化剂——二氯氧化钼(MoCl2O2)促进,这使得该方法成为一种高效、经济且环保的工业放大方法。
