  乙醇酸酯、乳酸和苹果酸酯的密度和粘度

  摘要：

  测量 12 种乙醇酸、 dl-乳酸和dl-苹果酸的酯和直链醇 C 1 –C 5的密度和粘度随温度的变化. 使用比重瓶和 Pinkevitch 毛细管粘度计在 293.15–363.15 K 的温度范围内获得密度和运动粘度，精度分别为 0.1 和 0.35%。获得的数据用于动态粘度计算。结果表明，酯的粘度-温度依赖性由 ASTM D341 模型描述，平均绝对相对偏差为 1%。动态粘度的温度依赖性使用类似 Arrhenius 的方程和 Vogel-Fulcher-Tammann (VFT) 模型进行拟合。发现可调参数A和B对于同源系列中的化合物具有相似的值。对于相应酸的每个系列的酯，这些参数被视为常数。VFT 模型比 Arrhenius 类方程更好地描述了酯的动态粘度 - 温度依赖性。已经回顾了一些预测密度的群可加性方法的能力，并与实验结果进行了比较。

  Bismaleimides (BMI) exhibit excellent heat resistance (high Tg and high resistance to thermal decomposition) compared to epoxy resins and phenolic resins, and therefore, in recent years, more attention is paid to bismaleimides as a resin material for the next-generation devices represented by SiC power semiconductors, in addition to the investigation on the use of bismaleimides for electronic material applications. As such, conventional BMI's are known as highly heat-resistant resins; however, there is a demand for a resin having higher heat resistance for advanced material applications and the like. Thus, an object of the invention is to provide a novel maleimide compound having superior heat resistance. Disclosed is a substituted or unsubstituted allyl group-containing maleimide compound having a structure with three or more benzene rings, having one or more groups each having a substituted or unsubstituted allyl group, and having one or more maleimide groups.

• Reductive Coupling of Aldehydes by H2S in Aqueous Solutions, a CC Bond Forming Reaction of Prebiotic Interest
  作者：Mohammed Kajjout、Yanek Hebting、Pierre Albrecht、Pierre Adam

  DOI：10.1002/cbdv.201100124

  日期：2012.4

  We report here a novel reductive coupling reaction of conjugated, non- or poorly enolizable aldehydes induced by H(2) S and operative in aqueous solutions under prebiotically relevant conditions. This reaction leads from retinal to β-carotene, and from benzylic aldehydes to the corresponding diarylethylenes. This novel reaction also opens a new potentially prebiotic pathway leading from glyoxylic acid
