对云南潦浒、寻甸、吉林舒兰蒙旦树脂中结合酸的化学组成及结构特征进行了对比研究 .结果显示 ,树脂结合酸均以正构烷酸为主要成份 ,其分布为C1 2 ～C2 8,高含量的正构烷酸集中在低碳数一端 ,C2 0 含量最高 ,其次为C1 6 ,而舒兰结合酸中 ,正构烷酸占绝对优势 ,且C1 6 为最高含量的化合物 ;去氢松香酸在每一个样品中含量较低 ,其它三环二萜酸 ,如松脂酸、三达松脂酸等异构体或立体异构体含量也非常低 ;具有五环三萜骨架的酸性物质 ,在潦浒、舒兰结合酸中比较丰富 ,其含量超过寻甸结合酸 ;在低碳数一端 ,存在着各种支链烷酸及苯甲酸、苯酚及取代物 .潦浒树脂结合酸与寻甸树脂结合酸无论从组成上和分布都是极其相似的 ,对比树脂烃 ,树脂游离酸的结果 ,可以肯定地得出蒙旦蜡原料煤生煤植物和生煤环境是极为相似的 ,而与舒兰蒙旦蜡原料煤之生源和环境存在着本质的差异 .
The chemical composition and structural characteristics of bound acid in Sulang Dan, Xundian, Jilin Shulan Mengdan resin were compared and studied.The results showed that n-alkanoic acid was the main component of the resin-bound acid, the distribution was C1 2 ~ C2 8, high concentration of n-alkanoic acid concentrated in the low-carbon one end, C2 0 highest content, followed by C1 6, Shulan combined acid, n-alkanoic acid accounted for absolute advantage, and C1 6 for the highest content Compounds; the content of dehydroabietic acid in each sample is low, the contents of other tricyclic diterpene acids, such as trityl acid and triadimeric acid are also very low; the content of pentacyclic triterpene skeleton Of the acidic substances, in the Liaohu, Shulan combined with acid rich, its content exceeds Xundian combined with acid; in the low end of the carbon number, there are a variety of branched-chain acids and benzoic acid, phenol and substitutes. Resin-bound acid and Xindian resin acid binding both in terms of composition and distribution are very similar to the comparison of resin, resin, free acid results can be sure that the raw material of montan wax coal raw coal plant and coal environment is extremely Similar to the source and ring of coal with Shulan Mengdan wax raw material There are differences in the nature.
