摘要
以莰烯和丙烯酸为原料,用强酸性阳离子树脂Amberlyst 15作催化剂合成了功能单体丙烯酸异冰片酯,考察了物料比、催化剂用量、阻聚剂种类及用量、反应温度、反应时间等因素对反应的影响,同时采用正交试验对工艺条件进行了优化,结果表明,较适宜的反应条件是n(丙烯酸)∶n(莰烯)为1.3∶1,催化剂Amberlyst 15用量占原料总质量的12%,阻聚剂吩噻嗪用量占原料总质量的0.03%,反应温度为60℃,在此条件下制备的丙烯酸异冰片酯得率为83.3%,选择性为94.6%。利用傅立叶变换红外光谱及气相色谱-质谱等分析手段对产物的结构进行了鉴定。
Functional monomer-isobornyl acrylate was prepared from camphene and acrylic acid using cation exchange resin-Am- berlyst 15 as catalyst. Effects of material ratio of camphene to acrylic acid, content of catalyst, types and content of inhibitors, the temperature, and the reaction time on reaction were investigated. Experimental results showed that the optimum conditions were material ratio of acrylic acid to camphene 1.3 ： 1, content of catalyst 12 % , content of phenothiazine 0.03 % , and the reac- tion temperature 60 ℃. The yield of isobornyl acrylate was 83.3 % , and the selectivity was 94.6 % under the above conditions. The structure of isobornyl acrylate was characterized by FT-IR and GC-MS.
