一种新型丙烯酰类功能单体的合成及表征

The synthesis and characterization of a new acrylamide functional monomer

以丙烯腈、莰烯和发烟硫酸为原料,合成了2-丙烯酰胺基-7,7-二甲基-1-磺酸甲基二环[2.2.1]庚烷;在适量的添加剂存在下,可提高产率到72%。并借助红外光谱、核磁共振和质谱确定了产物的结构。结果表明,2-丙烯酰胺基-7,7-二甲基-1-磺酸甲基二环[2.2.1]庚烷分子中含有"C═C"、二环[2.2.1]庚烷和磺酸基团,可以作为水溶性聚合物功能单体。

2-Acrylamido-7,7-dimethyl-l-sulfomethylbicyclo[2. 2.1] heptane was synthesized by using acryloni- trile, camphene and fuming sulfuric acid as raw materials. In the presence of a moderate additives, the yield in- creased to 72~. The products were characterized by IR and NMR. The results show that 2-acrylamido-7,7-dimeth- yl 1-sulfomethylbicyclo [-2.2.1] heptane contains carbon carbon double bond, bicycle [-2.2.1] heptanes and sulfonic acid group. This monomer can be used as water soluble functional monomer.
