Abstract

PURPOSE:To obtain filler for liquid chromatography having a fluoroalkyl group, which has high hydrophobic property ad is strongly bonded to a carrier having a hydroxyl group by directly introducing a specified fluorosilicon-based compound to the carrier. CONSTITUTION:Filler for liquid chromatography is obtained by introducing the fluorosilicon-based compound expressed by formula I into a carrier. R1 in the formula represents hydrogen atom or methyl group. R2 and R3 are the same or different groups and represent trimethylsilyl oxy group, alkyl group having the carbon number of 1-4, alkyl-carbonyl oxy group or alkoxyl group. RF expressed by formula II or formula III. (In the formulas, X represent hydrogen atom, fluorine atom or chlorine atom, n1 represents the integer of 1-10 and n2 represents the integer of 0-8). In the formulas, (m) represents the integer of 1-10, and l represents 1 or 0. When l is 0, R1 represents hydrogen atom. Since the fluoroalkyl group is directly introduced into the carrier by chemical bonding, the strong bonding to the carrier is imparted, and the high hydrophobic property and oil repelling porperty are shown. Therefore, this filler is useful as the filler for the liquid chromatography for which the hydrophobic property is required.
