摘要:选用湿地松松香和马尾松松香,不同种类的酸作用不同时间,分析了酸作用对枞酸型树脂酸和去氢枞酸含量变化的影响,研究了枞酸型树脂酸在酸作用下的变化规律。结果表明:在酸处理过程中,长叶松酸、枞酸、新枞酸之间发生相互异构,同时还有脱氢反应和脱羧等裂解反应发生,异构速度、脱氢速度和脱羧速度都与酸的种类、酸强度和反应时间有关。酸强度越大,异构速度、脱氢速度和脱羧速度越快。
Slash pine( P. elliottii) rosin and masson pine( P. massoniana) rosin were treated using different type of acids at different time. The variation relationships of abietic-type acids were analyzed through the content changes of abietic-type acids and dehydroabietic acid. The results showed that isomerization took place among palustric acid,abietic acid and neoabietic acid,and at the same time dehydrogenation and decarboxylation occurred under acid treatment. The rates of isomerization,dehydrogenation and decarboxylation were affected by the type of acid,acid strength and treating time. With the increase of acid strength,the speed of isomerization,dehydrogenation and decarboxylation increased.
