• Bio-Based Alternative to the Diglycidyl Ether of Bisphenol A with Controlled Materials Properties
  作者：Anthony Maiorana、Stephen Spinella、Richard A. Gross

  DOI：10.1021/acs.biomac.5b00014

  日期：2015.3.9

  series of biobased epoxy monomers were prepared from diphenolic acid (DPA) by transforming the free acid into n-alkyl esters and the phenolic hydroxyl groups into diglycidyl ethers. NMR experiments confirmed that the diglycidyl ethers of diphenolates (DGEDP) with methyl and ethyl esters have 6 and 3 mol % of glycidyl ester. Increasing the chain length of DGEDP n-alkyl esters from methyl to n-pentyl resulted

  由二酚酸（DPA）制备一系列生物基环氧单体，方法是将游离酸转化为正烷基酯，并将酚羟基转化为二缩水甘油醚。NMR实验证实，二酚盐的二缩水甘油醚（DGEDP）与甲基和乙基酯的缩水甘油酯的摩尔百分比分别为6和3摩尔％。将DGEDP正烷基酯的链长从甲基增加到正戊基会导致环氧树脂粘度大大降低（700至11 Pa·s）。用异佛尔酮二胺固化的DPA环氧树脂的储能模量也随正烷基酯链长的变化而变化（例如，对于甲基和正丁基，3300和2100 MPa-戊酯）。随着酯长度的增加，固化材料的α转变温度从158℃线性降低至86℃。对于所有测试的固化树脂（包括DGEBA），杨氏模量和拉伸强度分别约为1150和40 MPa，并且随酯长度的变化很小。由FTIR和DSC确定的不同环氧树脂的固化度接近理论最大值。这项工作的结果表明，正烷基双酚盐的二缩水甘油醚代表了一种新的生物基液态环氧树脂家族，其固化后具有与DGEBA相似的性能。

  The synthesis of DPE, a valid candidate to replace bisphenol A, has been accomplished in good yield (78 %) and selectivity (87 %) by using Aquivion, a recyclable perfluorinated polymeric resins. The two step reaction, successfully applied to other alcohols and phenols, is carried out following a one-pot procedure and using phenols as solvent-reagent.
