微波辅助的脱水糖衍生物羟甲基糠醛、乙酰丙酸、无水糖醇、及其醚的合成
摘要：
描述了使用微波(MW)照射产生脱水糖和脱水糖衍生物的方法以及纯化它们的方法。脱水糖衍生物包括5-羟甲基-2糠醛(HMF)和无水糖醇如脱水山梨糖醇以及异山梨醇。这些衍生物包括HMF醚、乙酰丙酸酯、和无水糖醇的醚衍生物。所述的方法比本领域已知的非微波介导的相似反应要求更低的反应温度和更短的反应时间。常见的反应条件是120-210C，并且常见的反应时间是30分钟或更短。
摘要（英）：

Methods for the production of dehydrated sugars and derivatives of dehydrated sugars using microwave (MW) irradiation and methods of purifying the same are described. The dehydrated sugars derivatives include 5-hydroxymethyl-2-furfural (HMF) and anhydrosugar alcohols such as sorbitans and isosorbide. The derivatives include HMF ethers, levulinic acid esters, and ether derivatives of the anhydrosugar alcohols. The described methods require lower reaction temperatures and shorter reaction times than similar non microwave mediated reactions known in the art. Typical reaction conditions are 120-210 DEG C., and typical reaction times are 30 minutes or less.
