制备方法与用途

季戊四醇硬脂酸酯（PETS）简介

季戊四醇硬脂酸酯（PETS）通常为白色硬质高熔点蜡状物，能溶于乙醇、苯等有机溶剂中。热失重TGA分析显示，在350℃时PETS没有明显的重量损失；375℃时，重量损失约2.5%；至400℃时，开始分解（重量损失约7%）。

特性

季戊四醇硬脂酸酯具有以下特性：

1. 脱模性——有效降低熔体粘度，用量少，脱模效果显著。
2. 高光泽——极低的浊化倾向，有助于增强透明塑料的透射率并改善成品外观。
3. 耐高温性——在高温下具有良好结构热稳定性和低挥发性。

应用

季戊四醇硬脂酸酯在高温条件下表现出良好的热稳定性和低挥发性，具有优异的脱模和流动性能，对部分结晶塑料有极好的成核作用。它常用于透明产品的生产中。

由于其出色的热稳定性，PETS适用于加工过程，不会发生降解，并且可以显著提高透明度及表面光洁度。在挤出和塑模加工过程中，PETS可作为许多聚合物的有效润滑剂，尤其适合于热塑性工程塑料的应用。此外，它也可用作PC、硬PVC及其他聚合物体系的外润滑剂。

化学性质

淡黄色粘稠油状液体，能溶于水及一般有机溶剂。

用途

主要用作橡胶助剂生产原料。

  摘要：

  通过晶种-结晶法合成了介孔SnO-γ-Al 2 O 3纳米复合材料，并研究了季戊四醇和硬脂酸催化酯化生产季戊四醇四硬脂酸酯的过程。通过常规水热合成制备的SnO-γ-Al 2 O 3也进行了比较研究。采用XRD、N 2吸附、NH 3 -TPD、SEM、27Al MAS NMR、吡啶-FTIR和CHNS分析。根据表征结果，晶种-结晶法有助于减小晶粒尺寸，提高晶粒的结晶度和分散度。表面积，尤其是外表面积、孔体积和尺寸增加，总酸度增加。强酸位转变为中强酸位，中强酸强度减弱。从而延缓了焦炭的形成，明显提高了季戊四醇转化率、季戊四醇四硬脂酸酯的选择性和催化稳定性。

These findings obtained with triolein as diffusion medium are compared with what is Known about the molecular weight dependency of diffusion coefficients in the diffusion media benzene, water, and rubber. Finally an attempt is made to establish a relationship between the values of D and the mechanical properties, especially flow properties, of the diffusion media in question.
