Linear mono- and dialkyl ethers of furan-2,5-dimethanol (FDM) and/or 2,5-bis(hydroxymethyl)tetrahydrofuran (bHMTHF), methods for their preparation, and derivative chemical compounds thereof are described. In general, the synthesis process entails a reaction of FDM or bHMTHFs in a polar aprotic organic solvent having a permittivity ( ) >8, at a temperature ranging from about -25C to about 100C, with either a) an unhindered Brnsted base with a pKa ?15 or b) a hindered Brnsted base having minimum pKa of about 16, and a nucleophile.
描述了呋喃-2,5-二甲醇(FDM)和/或2,5-双(羟甲基)四氢呋喃(bHMTHF)的线性单烷基和双烷基醚,它们的制备方法以及其衍生化学化合物。一般来说,合成过程包括在具有介电常数(ε)>8的极性无水有机溶剂中,将FDM或bHMTHFs与a)pKa?15的无阻碍Brønsted碱或b)具有约16的最小pKa的阻碍Brønsted碱和亲核试剂在温度范围从约-25°C到约100°C之间反应。
