Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 5680-79-5, Name is H-Gly-OMe.HCl. In a document, author is Duroux, Romain, introducing its new discovery. Category: amides-buliding-blocks.
System map for the ionic liquid stationary phase tri(tripropylphosphoniumhexanamido)triethylamine bis(trifluoromethylsulfonyl)imide for gas chromatography
The solvation parameter model is used to construct a system map for the retention of volatile organic compounds on the ionic liquid stationary phase tri(tripropypphosphoniumhexanamido)triethylamine bis(trifluoromethylsulfonyl)imide (SLB-IL76) over the temperature range 80-240 degrees C. The SLB-IL76 stationary phase is moderately cohesive and strongly dipolar/polarizable and hydrogen-bond basic but only a weak hydrogen-bond acid. Electron lone pair interactions are weak and make only a minor contribution to the retention mechanism. The separation properties of SLB-IL76 highlight the difficulty of designing new stationary phases from ion structures as the presence of amide groups in the cation don’t seem to contribute significantly to the hydrogen-bond acidity of SLB-IL76. The separation properties of SLB-IL76 are closest to the bis(polycyanopropyl)siloxane stationary phases with a high percentage of bis(cyanopropyl)siloxane monomer and could be used in method development when a stationary phase with similar gross retention characteristics but different selectivity is required.
