    Notes: Abstract A heat flow model is presented of the solidification process of a thin melt layer on a heat conducting substrate. The model is based on the two-dimensional heat conduction equation, which was solved numerically. The effect of coexisting regions of good and bad thermal contact between foil and substrate is considered. The numerical results for thermal parameters of the Al-Cu eutectic alloy show considerable deviations from one-dimensional solidification models. Except for drastic differences in the magnitude of the solidification rate near the foil-substrate interface, the solidification direction deviates from being perpendicular to the substrate and large lateral temperature gradients occur. Interruption of the thermal contact may lead to back-melting effects. A new quantity, the effective diffusion length, is introduced which allows some conclusions to be drawn concerning the behaviour of the frozen microstructure during subsequent cooling.

    Description / Table of Contents: Zusammenfassung Lösungen von Rutheniumnitrosylnitro-, Rutheniumnitrosylnitronitrato- und Rutheniumnitrosylnitrato-Komplexen lassen sich mit Hilfe von Papierelektrophorese, Extraktions-Chromatographie und Extraktionen eindeutig voneinander unterscheiden. Kontaktzeit, HNO3-Konzentration, NO 3 − -Konzentration, HDBP-Gehalt der organischen Phase und Zusatz von F−, SO 4 2− , H2PO 4 − und C2O 4 2− beeinflussen stark die Extraktion der Rutheniumnitrosylnitrato-Komplexe mit TBP in Dodecan.
    Notes: Summary Solutions of ruthenium-nitrosyl-nitro, ruthenium-nitrosyl-nitro-nitrato and ruthenium-nitrosyl-nitrato complexes can be distinguished clearly from each other by means of paper electrophoresis, extraction chromatography and extractions. The contact time, HNO3-concentration, NO 3 − -concentration, HDBP-content of the organic phase and the addition of F−, SO 4 2− , H2PO 4 − and C2O 4 2− exert a strong influence on the extraction of the ruthenium-nitrosyl-nitrato complexes with TBP in dodecane.

    Description / Table of Contents: p-Vinylbenzophenone was obtained by GRIGNARD reaction from p-chlorostyrene and benzonitrile and was polymerized radically in bulk and copolymerized with styrene. The compositions of the copolymers with styrene were determined from the infrared spectra. The following monomer reactivity ratios for the radical copolymerization at 60°C. were found: r1 = 3.0 ± 0.3 (for p-vinylbenzophenone) and r2 = 0.18 ± 0.08 (for styrene).p-Vinyltriphenylcarbinol was obtained by GRIGNARD reaction from p-chlorostyrene and benzophenone or from p-vinylbenzophenone and phenylmagnesium bromide. It was polymerized radically in bulk and in benzene solution and copolymerized with styrene. The compositions of the copolymers were determined by photometrical analyses of the polymer p-vinyltriphenylmethyl-cations in conc. sulfuric acid. For the radical copolymerization of p-vinyltriphenyl-carbinol with styrene in benzene at 50°C. the following monomer reactivity ratios resulted: r1 = 1.60 ± 0.15 (for p-vinyltriphenyl-carbinol) and r2 = 0.47 ± 0.10 (for styrene).
    Notes: p-Vinylbenzophenon wurde durch GRIGNARD-Synthese aus p-Chlorstyrol und Benzonitril erhalten; es wurde radikalisch in Substanz polymerisiert und mit Styrol copolymerisiert. Die Zusammensetzung der Copolymerisate wurde aus IR-Spektren bestimmt. Für die radikalische Copolymerisation bei 60°C gelten folgende Copolymerisationsparameter: r1 = 3,0 ± 0,3 (für p-Vinylbenzophenon) und r2 = 0,18 ± 0,08 (für Styrol).p-Vinyltriphenylcarbinol wurde aus p-Chlormagnesiumstyrol durch Umsetzung mit Benzophenon sowie aus p-Vinylbenzophenon und Phenylmagnesiumbromid erhalten; es wurde in Substanz und in benzolischer Lösung radikalisch polymerisiert und mit Styrol copolymerisiert. Die Zusammensetzungen der Copolymerisate wurden durch photometrische Bestimmung der polymeren p-Vinyltriphenylmethyl-Kationen in konz. Schwefelsäure ermittelt. Daraus ergaben sich für die radikalische Copolymerisation von p-Vinyltriphenylcarbinol mit Styrol in Benzol bei 50°C folgende Parameter: r1 = 1,60 ± 0,15 (für p-Vinyltriphenylcarbinol) und r2 = 0,47 ± 0,10 (für Styrol).
