Notes:
Summary A propyldimethylphenylsilane stationary phase was prepared by a hydrosilylation reaction on the double bond of an allyl bonded phase intermediate. The carbon load on the silica was between 8.8–9.0%. Evaluation of the material by FTIR indicated high conversion of the double bond by the hydrosilylation reaction. The bonded material displayed reversedphase properties as determined by the retention behavior of alkylarylketones but it was less hydrophobic than either C-8 or C-18. The stability at both low and high pH was excellent. Separations of pharmaceutical compounds, a mixture of anilines, and a mixture of dopamine and epinephrine were satisfactory.
