摘要
以萜烯树脂和邻苯二酚为原料,合成了萜烯-邻苯二酚树脂。采用柱层析法分离萜烯树脂和萜烯-邻苯二酚树脂,分别采用中性氧化铝和强碱性阴离子交换树脂作固定相,汽油、乙醇、NaOH-乙醇溶液作洗脱剂对萜烯树脂和萜烯-邻苯二酚树脂进行分离提纯。通过对洗脱液进行紫外光谱分析,表明用中性氧化铝作固定相,分别用汽油、乙醇和NaOH-乙醇溶液洗脱,能较好地分离萜烯树脂和萜烯-邻苯二酚树脂。
Synthesis of terpene-catechol resin from terpene resin and catechol was reported in this paper.Results showed that terpene-catechol resin could be synthesized directly with the proposed method.The synthesized terpene-catechol resin could be separated from terpene resin and catechol on neutral alumina column with petroleum,absolute ethanol and 5% NaOH-ethanol solution as eluates.Anion exchange resin was not suitable for the separation as stationary phase due to the strong adsorption toward catechol.The chemicals of eluates were measured by UV and IR.(Terpene-)catechol resin can be used for preparing copolymeric coating from terpene-catechol resin with raw lacquer.
