摘要/Abstract

摘要： 以歧化松香为原料、气相色谱为分析手段进行了脱氢枞酸单离方法的比较。分别采用胺化法、皂化法和超声波强化胺化反应结晶耦合法单离脱氢枞酸,并对不同的歧化松香原料进行了单离脱氢枞酸的研究,实验结果表明,采用自制的歧化松香为原料,超声波强化胺化反应结晶耦合法在 40℃ 时单离脱氢枞酸的效果最好,纯度达 99.99%,收率达 55.37%,并用GC、UV、IR、熔点仪和旋光仪对所制备的高纯度脱氢枞酸进行了分析鉴定,实验值与文献值基本一致。

Abstract: The comparison of isolation methods of dehydroabietic acid was carried out, using disproportionated rosin as raw material by GC method. Dehydroabietic acid was isolated from disproportionated rosin by methods of amination, saponification and aminating reaction-crystallization enhanced with ultrasonic wave, respectively. The isolating dehydroabietic acid from diffe-rent kinds of disproportionated rosins has been investigated. The results showed that the method of aminating reaction-crystallization enhanced with ultrasonic wave was the best to isolate the dehydroabietic acid from the self-made disproportionated rosin at the temperature of 40℃. The purity of dehydroabietic acid prepared was 99.99%. The yield of dehydroabietic acid was 55.37%. The high purity dehydroabietic acid prepared has been analyzed and confirmed by using GC, UV, IR, melting point instrument and polarimeter as well. The results are in agreement with the values in literature.

Key words: dehydroabietic acid, isolation, disproportionated rosin
