SEPARATION METHODS OF PYRROLIC COMPOUNDS IN CRUDE OIL
-
摘要: 本文介绍原油中吡咯类含氮化合物的两种分离方法及有关对比评价,重点讨论经典液相色谱法中使用国产、进口试剂分离的实验结果。分析表明原油中吡咯类化合物的分离已具备分析试剂国产化的条件,为该技术成为常规分析测试手段及开展原油中非烃化合物研究奠定了基础。Abstract: Two isolution methods of pyrrolic nitrogen fractions in crude oils are introduced and evaluated.The emphasis is emplaced on the experimental result of the method of column liqulid chromatgraphy using native and foreign solvent.The result showed that it was practicable to use native solvents instead of foreign ones to separate pyrrolic nitrogen fractions.
