摘要:以丙烯酸改性松香酸钠和氯丙烯为原料,十六烷基三甲基溴化铵为催化剂,对苯二酚为阻聚剂(用量为丙烯酸改性松香钠质量的0.2%),N,N-二甲基甲酰胺为溶剂(用量为丙烯酸改性松香钠质量的3倍),在微波辅助条件下,探讨了工艺条件对二元端乙烯基型松香衍生物丙烯酸改性松香烯丙酯得率的影响,确定了最佳工艺条件为:微波功率400 W,反应时间100 min,催化剂用量4%,物料配比n(氯丙烯)∶n(丙烯酸改性松香钠)2∶1,反应温度50℃,在此条件下产物得率高达92.2%。采用GC、GC-MS和FT-IR等技术表征了反应产物的结构,结果表明合成产物结构与目标产物结构一致。
Allyl acrylate-modified rosinate was synthesized by using sodium acrylic modified rosinate(SAMR) and a11yl chloride as raw materials,cetyl trimethyl ammonium bromide as catalyst, hydroquinone as polymerization inhibitor(0.2% of the mass of SAMR) and N, N-dimetylformamide as solvent( treble the mass of SAMR) under microwave irradiation. The influence of different reaction conditions on the yield of product was investigated. The optimum reaction conditions were microwave energy 400 W, reaction time 100 min, catalyst amount 4%, molar ratio of allyl chloride and sodium acrylic modified rosinate 1 : 1, reaction temperature 50 ℃, and the yield was 92.2% under these conditions. The structure of the product was characterized by GC, GC- MS and FF-IR. The results showed that the structure of the synthesized product and the target product was consistent.
