蒙旦树脂烃化学组成及结构特征

本文对中国三种蒙旦树脂烃潦浒树脂烃（ＬＨＴ），寻甸树脂烃（ＸＤＴ），舒兰树脂烃（ＳＬＴ）进行了ＧＣＭＳ分析，获取了树脂烃中单元化合物的组成和结构。结果表明，在这三种树脂烃中，主要是五环三萜烃类五环三萜烷，五环三萜烯，单环、二环、三环、四环芳构化五环三萜烷以及三环二萜烃类降松脂烷，降松香烷，降海松烷，松香烷，山达松脂烷，单环、二环芳构化三环萜烷。比较三种树脂的总离子色谱图，发现在寻甸蒙旦树脂烃和舒兰树脂烃中，五环二萜的各种化合物是该组分主要化学组成，尤其在舒兰蒙旦树脂烃中，具有四环芳构化的萜烷其含量占绝对优势。潦浒蒙旦树脂烃中，三环二萜的各种物质是其重要的化学组成。与此同时，阐述了中国蒙旦蜡精制漂白脱色不完全的原因。

CHEMICAL CONSTITUENTS OF HYDROCARBONS IN MONTAN RESINS FROM CHINESE MONTAN WAXES

In this paper, LHT, XDT, SLT the hydrocarbon fractions, of Montan resins extracted respectively from Montana waxes of Liaohu (Yunnan province), Xundian (Yunnan province) and Shulan (Jilin province) have been studied on GCMS and both of the chemical constituents and structures of hydrocarbons are obtained. The results show that the hydrocarbons consist mainly of pentacyclic triterpanoid and their aromatized triterpanepentacyclic hopane, pentacyclic hopene, Aringaromatized triterpane, A,Bringdiaromatized triterpane, A,B,Cringtriaromatized triterpane A,B,C,Dringtetraaromatized triterpane, B,C,Dringtriaromatized triterpane as well as tricyclic diterpanes and their aromatized tricyclic terpanesNorsandaracopimarane, Norpimarane, Norabietane, Sandarcopimarane, Abietane, 1,2,3,4Tetrahydroretene, 18Norabietane8,11,13triene, Retene etc. Compared with TIC of LHT, the compounds with pentacyclic triterpanoid skeleton are main chemical compositions and the A,B,C,Dringtetraaromatized triterpanes are dominant in hydrocarbon fractionsof XDT and SLT. Contrary to XDT and SLT, the compounds with tricyclic skeleton are important compositions in LHT. The reasons why the colourless of excellent light colour montan waxes are not able to be made by oxidation of rude montan waxes and montan resin removed montan waxes in China are also described.
