  Synthesis and characterization of dibutyltetramethyldisilazane-bonded silica phases for reversed-phase high-performance liquid chromatography

  摘要：

  A new sllane, dl-n-butyltetramethyldisllazane (DBTMDS), has been synthesized. Sllanizations with DBTMDS of a narrow-pore and a wide-pore silica yielded relatively high concentrations of bonded n-butyl ligands, of 4.22 and 4.09-mu-mol/m2, respectively. The chromatographic properties of the n-butyl bonded phase (C4-NH), synthesized with DBTMDS, were compared with n-butyl bonded phases (C4-CL) synthesized with n-butyldimethylchlorosilane (BDMCS) and Vydac-C4 under the same chromatographic conditions. The adsorption of basic compounds including N,N-diethylaniline (N,N-DEA), dansylarginine (Dns-Arg), and (phenylthlo)hydantoin-arginine (PTH-Arg), as well as several polypeptides and small proteins including angiotensin I, angiotensin II, and lysozyme, was shown to be less for the C4-NH sorbents than for C4-CL and Vydac-C4 sorbents. While the S value for the basic protein lysozyme was significantly lower on the wide-pore C4-NH sorbent, the S and log K0 values for a range of selected proteins were comparable to those obtained with the Vydac-C4 sorbent. The tests of hydrolytic stability of the bonded phases showed significantly greater stability for the C4-NH sorbents than for the C4-CL sorbents under isocratic mobile-phase conditions of 10 % and 40 % acetonitrile with 0.1 % TFA.
