用有机溶剂从泥煤、褐煤中萃取得到的蜡,国外通称为蒙旦蜡(Montan Wax)。关于蒙旦蜡组成的研究已有许多报道,由于所研究物质的复杂性,加之缺乏精密的分析仪器,故早期的报告结果出入较大。只是近20年采用了现代的测试手段,才对蒙旦蜡的组成有了较清楚的了解。蒙旦蜡是一个包含1000多种化合物的复杂体系,已鉴定出的化合物约200种。采用选择性有机溶剂可将蒙旦蜡分成三个主要组份:纯蜡、树脂,似地沥青物质。 Wax extracted from peat and lignite with organic solvents is commonly known abroad as Montan Wax. Much has been reported about the composition of Montan wax, which has been reported earlier due to the complexity of the materials studied and the lack of sophisticated analytical instruments. Only nearly 20 years using modern testing methods, the composition of Montan wax has a clearer understanding. Montan wax is a complex system of more than 1000 compounds with about 200 compounds identified. Montan wax can be separated into three major components using a selective organic solvent: pure waxes, resins, and asphaltic materials.
