硝酸正丙铵和硝酸异丙铵气相色谱性质的研究

Study on Gas Chromatographic Properties of Propylammonium Nitrate and Isopropylammoaiam Nitrate

本文研究了硝酸正丙铵和硝酸异丙铵的气相色谱性质,并以 PEG—20M 为参考相,经测得它们的液体使用温度范围分别为20—120℃及20—140℃。该固定相对于极性化合物,特别是具有氢键成键能力的化合物具有良好的选择性。比如对醇美,尤其是对醇类异构体的分离效果更佳。对于酯类,酮类以及单官能团取代苯的分离效果令人满意。

Propylammonium and isopropylammonium nitrate are studide as Stationary phases for gas chromatography. Carbowax 20M is used as the reference polar phase. A column temperature range of 20-120C and 20-140C were used for this work. And a good selectivity for potar Compounds, in especial for Compounds having hydrogen bonding function groups. Such as alcohols. The effect of separation is better for alcoholic isomeride. The function is satisfactory for esters. Ketones and monofunctional benzene derivatives.
