摘要 以脱氢枞酸为原料,以草酰氯为酰基化试剂(摩尔比1∶1),先合成脱氢枞酸酰氯,然后再与丙烯酸-β-羟基乙基酯酯化(摩尔比1∶1),合成脱氢枞酸(β-丙烯酰氧基乙基)酯,得率75%,质量分数98.5%。用FTIR、GC-MS、^13CNMR和DSC对其结构和性能进行了表征。结果表明,脱氢枞酸(β-丙烯酰氧基乙基)酯是一种熔点为59-61℃的白色晶体,在引发剂的存在下,可以发生聚合反应,均聚物玻璃化转变温度约为54.2℃。 (2-Acryloyloxy) ethyl ester of dehydroabietic acid with mass fraction of 98.5% was synthesized by reacting dehydroabietic chloride with hydroxyethyl acrylate (molar ratio 1:1 ) in 75% yields and characterized by using FTIR spectroscopy, GC/MS, ^13 CNMR spectroscopy and DSC. The product is white crystal with mehing point 59 -61 ℃. It can polymerized in the presence of initiator and the glass transition temperature of the polymer is about 54. 2 ℃.
