Improving the Resolution of Diisopropylnaphthalene by Gas Chromatography

二异丙基萘是一种重要精细化工原料。本文使用气相色谱法对二异丙基萘中不同的异构体组分进行分离和检测。利用强极性的毛细管色谱柱,探究了进样量,载气线速,柱温等条件对二异丙基萘分离度的影响。通过条件优化,获得了最佳的分离度条件,实现对二异丙基萘异构体组分中目标物质2,6-DIPN和2,7-DIPN的定性和定量分析,为提高二异丙基萘的分离度一定的提供理论指导。

Diisopropylnaphthalene is an important fine chemical raw material.Different isomers in diisopropylnaphthalene were separated and detected by gas chromatography.The effects of injection volume,carrier gas linear velocity,column temperature and other conditions on the resolution of diisopropylnaphthalene were investigated by a highly polar capillary column.Through condition optimization,the optimal resolution conditions were obtained to achieve the accurate determination of 2,6-DIPN and 2,7-DIPN,the target substances in diisopropylnaphthalene isomers,and provide theoretical guidance for improving the resolution of diisopropylnaphthalene.
