润滑油中一般都含有少量氮、硫或氧的化合物。由于这类化合物在存放过程中会发生化学变化,使润滑油颜色改变,油质劣化,严格控制其含量是必需的。 润滑油及其所含非烃极化化合物都是以混合物状态存在,要对它们进行组成分析比较困难,一般都是以经典柱色谱法测定其总量。但是,这种方法费时而麻烦。本文用棒状薄层色谱氢焰扫描仪(1)测定润滑油中非烃总含量,简便、快速,比较准确。
Lubricants generally contain small amounts of nitrogen, sulfur or oxygen compounds. As these compounds in the storage process will occur chemical changes, so that the color change of lubricating oil, oil deterioration, strict control of its content is necessary. Lubricating oils and non-hydrocarbon polar compounds contained in them all exist as a mixture. It is difficult to analyze the composition of the lubricating oil and its components, and the total amount thereof is determined by classical column chromatography. However, this method is time consuming and troublesome. In this paper, rod-shaped thin layer chromatography hydrogen flame scanner (1) Determination of total non-hydrocarbon oil content, simple, fast, more accurate.
