    Notes: Abstract A monitor is described which provides the on-line determination of mercury in river water at concentrations from 20 to 1000 ng/L. The measurement includes an on-line digestion with Br–/BrO3 – and UV-radiation. Each determination is controlled by an on-line addition of 50 and 100 ng/L mercury carried out by pre-dilution of a 500 and 1000 ng/L stock solution using sequential injection analysis (SIA). One cycle of analysis takes 20 min and results in nine signals. A five days stand-alone operation has been performed successfully.

    Kinetische Untersuchung zur platinkatalysierten Hydrosilylierung von Vinylsiloxanen mit Hydrogensiloxanen (1994)

    Notes: Kinetic Investigation of the Platinum-catalysed Hydrosilylation of Vinylsiloxanes with HydrogensiloxanesA kinetic investigation of the platinum-catalysed hydrosilylation of monofunctional oligomeric vinylsiloxanes by monofunctional oligomeric hydrogensiloxanes was performed under stoichiometric conditions with use of quantitative 1H-NMR spectrometry. The reaction rate up to 50% conversion can be expressed by v=k [Pt]. During further hydrosilylation the kinetic changed to second order. No induction period was observed. A hydrogensiloxane with a dimethylsilyl end group gives much higher rates than a siloxane with a methylsiloxy group. The main reactions of all hydrosilylations, determined by GC-MS and 29Si-NMR, are β-additions. Less then 5% α-products are obtained.

    Notiz zur quantitativen Bestimmung von Si-H- und Si-Si-Gruppen (1968)

    Description / Table of Contents: Zusammenfassung Eine einfache und genaue Methode zur Bestimmung von Si-H- und Si-Si-Gruppen wird vorgeschlagen, die auf alkalischer Hydrolyse der Substanz in einem verschlossenen und evakuierten Kolben und AuswÄgen des dem entwickelten Wasserstoff entsprechenden Wasservolumens beruht. Bei H-Gehalten von 1–2% betrÄgt die Genauigkeit ± 0,03% (abs.).
    Notes: Abstract A simple, robust and surprisingly exact method for the quantitative determination of Si-H- or Si-Si-groups is based on alkaline hydrolysis of the Si-H- or Si-Si-containing substances in a sealed and evacuated vessel and weighing of the volume of water equivalent to the developed volume of hydrogen. The accuracy is ± 0.03% (abs.) with H contents of 1–2%.
