• Dilatometric properties of some butyropalmitins, butyrostearins, and acetopalmitins
  作者：R. O. Feuge、N. V. Lovegren

  Six aceto‐ and butyroglycerides, including di‐and triglycerides, were prepared and purified, and a number of their physical properties were determined.

  Melting and transition points for each of the glycerides were determined by experiments with small portions of the samples in capillary tubes; the “thrust‐in” technique was employed to detect some polymorphic transitions occurring in intervals as short as one second.

  Using the data on melting and transition points, dilatometric data were obtained, insofar as possible, for the various crystalline modifications of the compounds as well as for the liquid state. From the dilatometric data calculations were made for expansibilities in the liquid and various solid states, and melting dilations for several solid states. In one instance the volume change on phase transition, without melting, was calculated.

  From X‐ray diffraction patterns the long and short crystal spacings for the highest melting forms of several of the glycerides were determined. On the basis of the short spacings, polymorphic designations commonly used for fats and oils were assigned. The long spacings obtained indicated a triple chain length structure for some of the compounds and as yet an undetermined structure for the other compounds.

  摘要 制备并纯化了六种乙酰甘油酯和丁酰甘油酯，包括二甘油酯和三甘油酯，并测定了它们的一些物理性质。 通过对毛细管中的小部分样品进行实验，确定了每种甘油酯的熔点和转变点；采用 "插入 "技术检测了一些在短至一秒的时间间隔内发生的多态转变。 利用熔点和转变点的数据，尽可能地获得了化合物各种晶体转变和液态的稀释计量数据。根据稀释度数据，计算出了液态和各种固态的膨胀率，以及几种固态的熔化膨胀率。在一个例子中，计算了相变时的体积变化，而没有熔化。 根据 X 射线衍射图样，确定了几种甘油酯最高熔化形态的长短晶体间距。根据短晶距，确定了油脂常用的多晶型名称。所获得的长晶距表明某些化合物具有三链长度结构，而其他化合物的结构尚未确定。
• Preparation of Low Calorie Structured Lipids Catalyzed by 1,5,7-Triazabicyclo[4.4.0]dec-5-ene(TBD)-functionalized Mesoporous SBA-15 Silica in a Heterogeneous Manner

  SBA-15 material has been found to be an efficient solid catalyst for the interesterification between tributyrin and methyl stearate in a solvent-free system for the production of low-calorie structured lipid (LCSL). The solid base catalyst was characterized by using small-angle X-ray scattering, Fourier transform infrared spectra, thermo gravimetric analysis, scanning electron microscopy, transmission electron

  1,5,7-三氮杂双环[4.4.0]癸-5-烯（TBD，一种强双环胍碱）官能化的SBA-15材料已被发现是一种高效的固体催化剂，可用于甘油三丁酸酯和硬脂酸甲酯之间的酯交换。用于生产低热量结构化脂质（LCSL）的无溶剂系统。固体碱催化剂的特征在于使用小角X射线散射，傅立叶变换红外光谱，热重分析，扫描电子显微镜，透射电子显微镜，氮吸附-解吸和元素分析技术。通过反相高效液相色谱法分析获得的LCSL的三酰基甘油组成。各种反应参数的影响，例如底物比例，反应温度和反应时间，对酯交换反应进行了系统的研究。当使用硬脂酸甲酯/三丁酸甲酯的摩尔比为2：1时，在80°C下1 h内可得到90％以上的LCSL。所获得的固体催化剂可以容易地回收，并且在活性损失可忽略不计的情况下重复用于若干循环。通过使用固体碱催化剂，开发了一种以非均相方式进行酯交换反应的环保的，更良性的方法。

  Lipid compositions are provided exhibiting the functionality of a typical shortening or filler fat, but are achieved with reduced and essentially zero trans-unsaturated fatty acids and that deliver reduced caloric content. By one approach, the functional lipid compositions include a blend of a matrix building ingredient, which is preferably a structured glycerol ester, and an edible liquid oil diluent in ratios such that the lipid composition exhibits the functionality of the traditional shortening or filler fat.
