  Monoglyceride-Based Organogelator for Broad-Range Oil Uptake with High Capacity

  摘要：

  Oil/water separation has been a worldwide subject because of increasing release of oil-containing wastewater as well as several marine oil spills. The phase-selective organogelators (PSOGs) are thought to offer a potential and effective implement for addressing this issue. An ideal PSOG for oil adsorption must fulfill some requirements involving effective gelation, easy synthesis, low cost, and recyclable for reuse. However, beyond those, the ability of gelation for a broad-range oil phase without selectivity is also important. However, most of the reported PSOGs have limitation in this respect thus far. In this paper, a new class of saturated 1-monoglyceride-derived organogelators can efficiently uptake almost all of the common fuel oils from water and gelate organic solvents with extremely low minimum gelation concentration (MGC). In addition, the oils in the gel and gelator molecules can be recovered quantitatively through simple vacuum distillation.

  同系可结晶马来酸正烷基酯和衣康酸单酯的热性能比较研究

  摘要：

  摘要 合成了具有马来酸酯或衣康酸酯端基的可结晶C8-C​​22偶数烷烃低聚物的同源系列。它们的总相变焓 (ΔHtpce) 和熔化时的熵 (ΔStpce)，由 DSC 测定，显示出与烷基链碳数的线性相关性。与相应的琥珀酸酯衍生物进行了比较。鉴于通过组可加性方法估计的 ΔStpce 值，检查了端函数对 ΔStpce 的影响。可以证明实验和估计熵值之间的公平一致性。热重分析 (TGA) 表明，马来酸酯低聚物不如相应的琥珀酸酯和衣康酸酯衍生物稳定。这种行为可以通过降解过程的活化能来证实。

  The hair treatment composition contains a combination of at least one itaconic acid monoester/acrylate copolymer and at least one polystyrene sulfonate with a molecular weight in a range from 50,000 to 200,000. The itaconic acid monoester monomer or monomers are of formula CH 2 ═C(COOR 1 )CH 2 COOR 2 , wherein one of R 1 and R 2 represents hydrogen and another of R 1 and R 2 represents —(CH 2 CH 2 O) x —R 3 , x is a number between 1 and 100 and R 3 is an alkyl group with 8 to 30 carbon atoms. In an especially preferred embodiment the hair treatment composition contains an itaconic acid monocetyl ester/acrylate copolymer and an itaconic acid monostearyl ester/acrylate copolymer.
