Abstract

Garnissages à pellicule organique liée pour colonnes chromatographiques. On prépare des garnissages fortement efficaces pour colonne chromatographique en faisant réagir les groupes hydroxyle sur la surface de la silice avec SiCl4 puis en faisant réagir la surface chlorosilylée avec un polyglycol ou un polyester de glycol dans une réaction en suspension; les groupes chlorosilane résiduels sur la surface qui n'ont pas réagi sont neutralisés en faisant réagir le méthanol ou d'autres acanols inférieurs. La silice modifiée obtenue a une pellicule superficielle organique liée essentiellement monomoléculaire qui donne une stabilité thermique, une efficacité uniforme et permet une analyse rapide quand le matériau est utilisé comme garnissage de colonne dans la chromatographie liquide-gaz.Bound organic film packings for chromatographic columns. Highly effective chromatography column packings are prepared by reacting the hydroxyl groups on the surface of silica with SiCl4 and then reacting the chlorosilylated surface with a polyglycol or a glycol polyester in a suspension reaction; residual chlorosilane groups on the unreacted surface are neutralized by reacting methanol or other lower acanols. The obtained modified silica has an essentially monomolecular bonded organic surface film which gives thermal stability, uniform efficiency and allows rapid analysis when the material is used as a column packing in liquid-gas chromatography.
