  大豆油的模型研究与ADMET聚合

  摘要：

  AbstractGrubbs' ruthenium catalyst 2 has been employed in model studies of the acyclic diene metathesis (ADMET) polymerization of soybean oil. In the presence of 0.1 mol% of catalyst 2, the ADMET polymerization of ethylene glycol dioleate afforded the isomerized (E)‐dioleate (27%), dimer (18%), trimer (13%), tetramer (7%), pentamer (5%), hexamer (4%), heptamer (4%), and 9‐octadecene (21%). Only a trace of any intramolecular cyclized product was formed. Under the same conditions, glycerol trioleate underwent ADMET polymerization to produce dimer, trimer, tetramer, pentamer, and monocyclic oligomers, with monocyclic oligomers predominating. The high number of repeat units in the monocyclic oligomers (n≅6, 10, and 21) in dicates that cross‐linking occurs readily in this process. Based on our model system studies, we have examined the ADMET polymerization of soybean oil and succeeded in producing polymeric materials ranging from sticky oils to rubbers.

• Synthesis and Characterization of Novel Diol, Diacid and Di-isocyanate from Oleic Acid
  作者：Latchmi Raghunanan、Jin Yue、Suresh S. Narine

  DOI：10.1007/s11746-013-2376-z

  日期：2014.2

  Novel linear diol 2, diacid 3, and diisocyanate 4 with functional groups located at each end of the chain have been produced from oleic acid via a diester precursor. All the compounds were fully characterized by IR, 1H NMR, 13C NMR and Mass Spectrometry. These unbranched terminally‐functionalized compounds are important monomers for the manufacture of biodegradable thermoplastic polyurethanes and polyesters

  具有功能性基团位于链的每个末端的新型直链二醇2，二酸3和二异氰酸酯4是通过二酯前体由油酸制备的。通过IR，1 H NMR，13 C NMR和质谱对所有化合物进行充分表征。这些未支化的末端官能化化合物是制造可生物降解的热塑性聚氨酯和聚酯的重要单体。通用的合成方案也应证明可用于由任何不饱和脂肪酸合成二醇，二酸和二异氰酸酯。
