The reagent was generated in situ by sequential addition of 1.63 mL of triethylamine trishydrofiuoride (obtained from Riedel deHaen, Merck, or Aldrich Chemical Company, Inc.) and 2.80 mL of triethylamine to the solution of 2. The procedure reported in reference 4 provides a reagent with an approximate stoichiometry of NEt3-2HF that can also be used for the purpose described.5... [Pg.233]

Table 8 lists additives and the possible impurities they might present. The limits for these impurities were taken from manufacturers specification bulletins. To compound Table 8, products of pharmacopeial grade (USP, BP, Ph. Eur., DAB) were selected from qualified suppliers (Merck, Aldrich, Sigma, Fluka, EMS, Riedel deHaen). [Pg.467]

A solution of 2% w/v of dichloromethyl silane in octamethyl cyclooctasilane or octmethylcyclotetrasiloxane is used to inhibit the sticking of polyacrylamide gels, agarose gels and nucleic acids to glass surfaces and these chemicals are available commercially [from Fluka (Riedel-deHaen)]. [Pg.4]

Hydroquinones — quinones [1, 533-534, at end]. The most convenient synthesis of 4,5-dimethoxy-o-benzoquinone (8) involves oxidation of catchol (7) with lead dioxide (Riedel-deHaen) in the presence of sodium methoxide.7a... [Pg.393]

The most interesting effec is that shown by a luminescent sample of zinc oxide (zinc oxide 4/1414t is a Riedel-deHaen preparation of Rt owski, activated by heating zinc oxide 14 was activated by Ag-addition in NaCl and showed a bright luminescence). The rate of hydrogen peroxide formation from water in the dark increased with increasing luminescence, but the light reaction decreased. The introduction of electron traps, hence, diminishes the photocatalytic effect. [Pg.234]

The application of pressure to the liquid phase in liquid chromatography generally increases the separation (see HPLC). In PIC also, improved efficiency of the column is observed if pressure is applied to the mobile phase (Wittmer et al. Anal Chem 47 1422 1975).
