    Mischkristallbildung von As2O3 und Sb2O3 (1963)
    Springer
    Monatshefte für Chemie 94 (1963), S. 366-372 
    Details
    ISSN: 1434-4475

    Topics: Chemistry and Pharmacology
    Notes: Zusammenfassung Durch Wegkochen von NH3 aus ammoniakalischen Tartratlösungen des As2O3 und Sb2O3 in verschiedenem Verhältnis wurden einerseits monokline Mischkristalle der Oxyde mit einem Gehalt zwischen 100 und 70 Molprozent Arsen, andererseits kubische Mischkristalle mit 30 bis 100 Molprozent Antimon gewonnen. Die analytischen Ergebnisse werden durch Röntgen- und Infrarot-Untersuchungen bestätigt, aus den letzteren ergeben sich weitere Hinweise auf die Struktur.

    Description / Table of Contents: Abstract The following new compounds of mercury, or new modifications thereof were prepared, either from ammoniacal solutions of Hg(II)-salts by evaporation of ammonia at different temperatures, or by heating them to 200°: (HgNH2)NO3 cubic, (Hg2N)NO3 and (Hg2N)2HPO4 tetragonal, (Hg2N)2CrO4 cubic. (Hg2N)ClO4 hexagonal changes to a cubic form at 200°. All compounds yield well defined X-ray diagrams.
    Notes: Zusammenfassung Durch Entfernung von NH3 aus Quecksilber-Komplexsalzlösungen bei verschiedenen Temperaturen, bzw. durch Tempern bei 200° wurden folgende Verbindungen bzw. Modifikationen neu hergestellt: (HgNH2)NO3 kubisch, (Hg2N)NO3 tetragonal, (Hg2N)2CrO4 kubisch, (Hg2N)2HPO4 tetragonal. (Hg2N)ClO4 hexagonal wandelt sich bei 200° in die kubische Form um. Alle Verbindungen geben eindeutige Röntgendiagramme.

    Interlaboratory study of analysis of phenoxymethylpenicillin by liquid chromatography (1998)

    Notes: Summary A liquid chromatography method for analysis of phenoxymethylpenicillin has been examined in a collaborative study involving 6 laboratories. The method comprised an isocratic part, which is used in the assay. When the isocratic part is combined with gradient elution, the method is suitable for purity control. Five samples of phenoxymethylpenicillin (potassium salts and acid) were analysed. The main component, the most important side product 4-hydroxyphenoxymethyl-penicillin and other impurities were determined. An analysis of variance proved the absence of consistent laboratory bias. Laboratory-sample interaction was not significant. Estimates of the repeatability and reproducibility of the method, expressed as standard deviations (SD) of the result of the determination of phenoxymethylpenicillin, were 0.50 and 0.63 respectively.
