  一种含多氟链的双丙烯酸酯及其合成方法

  摘要：

  本发明公开了一种含多氟链的双丙烯酸酯及其合成方法，其中含多氟链的双丙烯酸酯结构通式如下：Rf为C3‑C20全氟碳基团；R’为二价的CO或SO2基团；R1、R3为相同或不同的C2‑C6二价烷基基团；R2为H或者C1‑C3一价烷基基团；n为大于或等于1的整数。其合成步骤如下：1）二羟烷基胺化合物与全氟碳基团取代甲酸的衍生物反应得到二羟烷基全氟甲酰胺；2）N2保护下，将丙烯酰卤缓慢滴加至二羟烷基全氟甲酰胺中，反应1~5小时，得到目标产物。采用本发明的方法合成含多氟链的双丙烯酸酯，工艺简便、产物的产率和纯度都比较高，得到的含多氟链的双丙烯酸酯可应用于合成含氟树脂或者应用于低表面能的光固化材料中。

  The implementations described herein relate to imidazoline quaternary ammonium based compositions, processes for the preparation thereof and to the use of imidazoline quaternary ammonium based compositions as anti-agglomerants. In some implementations, the anti-agglomerant compositions described herein are able to handle greater than 10° C. subcooling in a sour system up to 40,000 ppm H 2 S and also without the need for a hydrocarbon phase. It is believed that some of the anti-agglomerants described herein can function without a hydrocarbon phase in sour conditions.
