Structure Analysis of Petroleum Sulfonate Used in Tertiary Oil Recovery by GC-MS
Pages: 336-339
Year: Issue:  3
Journal: Petrochemical Technology

Abstract: 采用萃取法纯化工业石油磺酸盐试样;在N,N-二甲基甲酰胺溶液中以三氟乙酸酐为Lewis酸、KI为强亲核试剂,对纯化后的石油磺酸盐进行快速还原衍生化,并对衍生产物进行GC-MS分析.实验结果表明,当衍生反应体系中的n(石油磺酸盐):n(KI):n(三氟乙酸酐)=1:20:20时,衍生效果最优.采用HP-5石英毛细管柱,在程序升温(起始温度90 ℃保持2 min,然后以4 ℃/min的速率升至300 ...
