摘要
以CuCl2为催化剂,松节油、邻苯二酚为原料合成了萜烯 邻苯二酚树脂(简称TCR),对产物进行了红外、紫外光谱分析以及分子质量测定,考察了反应条件对实验结果的影响,并初步探讨了聚合反应产物的性能。结果表明,在CuCl2催化剂的作用下,邻苯二酚与萜烯发生聚合反应,产物TCR的数均分子质量为536,它易溶于有机溶剂,与萜烯酚树脂和萜烯树脂相比,具有良好的成膜性能;本实验较佳的反应条件为:n(萜烯)/n(邻苯二酚)为3∶1,催化剂用量为反应物质量的4.59%,温度为158℃,反应时间24h。
Terpenecatechol resin(TCR) was prepared from turpentine and catechol with CuCl2 as catalyst.The condition of the reaction was discussed.Structure of the product was analyzed by UV and IR,and average molecular weight of TCR was measured.Results showed that TCR was synthesized by reacting catechol with terpene.Filmforming properties of TCR were superior to those of terpenephenolic resins and terpene resins.Optimum reaction conditions were as follows:reaction time 24 h,temperature 158 ℃,terpene:catechol 3∶1(molar ratio),dosage of catalyst 4.59%.
