    Description / Table of Contents: Interactions between creep deformation and hot gas corrosionThe paper starts with a short explanation of the basic processes during the high temperature corrosion and of deformation under creep stress.Corrosion may give rise to an increase or a decrease of creep resistance, or it may result in an increase of the stress applied. The individual mechanisms are explained and, as far as possible, illustrated by examples. As a rule, however, several factors act simultaneously. The concerted actions is further complicated by back effects of a creep deformation on the corrosion processes. In the case of iron and nickel base alloys there exist obviously critical strain rates beyond which corrosion is enhanced and then proceeds more pronouncedly at the grain boundaries. It is also possible that then internal corrosion processes are triggered, in particular, in the grain boundary regions.While a qualitative assessment of the relationships between corrosion and creep deformation is possible, the feasibility of a quantitative description is still far away. As a rule, however, the aspect of a strength decrease will prevail although, in principle, corrosion may give rise to a strengthening, too.
    Notes: Einleitend werden kurz die Grundvorgänge der Heißgaskorrosion und der Verformung unter Zeitstandbeanspruchung erläutert.Die Korrosion kann den Kriechwiderstand erhöhen oder erniedrigen oder aber auch die anliegende Spannung vergrößern. Die einzelnen Mechanismen werden erläutert und - soweit möglich - durch Beispiele belegt. In der Regel wirken jedoch gleichzeitig mehrere Faktoren ein. Das Zusammenspiel wird durch Rückwirkungen der Kriechverformung auf die Korrosionsvorgänge weiter kompliziert. Für Eisen- und Nickelbasislegierungen gibt es offenbar kritische Dehngeschwindigkeiten, bei deren Überschreiten die Korrosion verstärkt und stärker korngrenzenorientiert abläuft. Auch innere Korrosionsvorgänge können dadurch besonders im Korngrenzenbereich ausgelöst werden.Während die Zusammenhänge zwischen Korrosion und Kriechverformung qualitativ überschaubar sind, liegt die Möglichkeit einer quantitativen Beschreibung noch in weiter Ferne. In der Regel werden die „Negativ-Punkte“ überwiegen, obgleich im Prinzip die Korrosion auch eine Verfestigung bewirken kann.

    Description / Table of Contents: The reaction of hydrogen sulfide with sulfuryl chloride in the ratio 2:1 leads in benzene solution to hydrogen chloride, water, sulfur, and disulfur monoxide, S2O, which is surprisingly stable under the prevailing conditions. The reaction of sulfuryl chloride with liquid hydrogen sulfide leads to the formation of sulfanes and chlorosulfanes, respectively, besides other products, depending on the molar ratio H2S:SO2Cl2.
    Notes: Schwefelwasserstoff reagiert mit Sulfurylchlorid beim molaren Einsatz 2:1 in benzolischer Lösung unter Bildung von Chlorwasserstoff, Wasser, Schwefel und Dischwefelmonoxid S2O, das unter den herrschenden Reaktionsbedingungen überraschend stabil ist. Mit flüssigem Schwefelwasserstoff bildet SO2Cl2 im Unterschuß u. a. Sulfane, im Überschuß Chlorsulfane.

    Description / Table of Contents: The separation of sulfane-disulfonates, sulfite and thiosulfate by anion-exchangers has been studied. Whereas K2S6O6 is decomposed on the column, the salts K2S3O6, K2S4O6 and K2S5O6 may be separated quantitatively.
    Notes: Die Trennung von Sulfan-disulfonaten, Sulfit und Thiosulfat mit Anionenaustauschern wird untersucht. Während K2S6O6 auf der Säule zu rasch zerfällt, lassen sich die Salze K2S3O6, K2S4O6 und K2S5O6 quantitativ voneinander trennen.

    Description / Table of Contents: The reaction S + 2 HJ → H2S + J2 of S8 solutions in CCl4 is very slow, but is accelerated very much in the case of S6 or Sx* (formed by splitting of S8 rings under the influence of light). A simultaneous determination of content and oxidation state of sulfur in mixtures of sulfur compounds with elemental sulfur by the “HJ method” therefore is only possible if the elemental sulfur is present in the S8 form and if the violet and ultraviolet part of the spectrum is excluded during the experiment.
    Notes: In CCl4 gelöster S8-Schwefel reagiert mit HJ nur sehr langsam nach S + 2 HJ → H2S + J2. Diese Reaktion verläuft dagegen mit S6 bzw. mit den durch Lichteinfluß erzeugten Spaltprodukt des S8-Ringes, Sx*, rasch, weshalb die „Jodwasserstoffmethode“ zur Ermittlung des Gehaltes und der Oxydationsstufe von Schwefel in Gemischen des Elementes mit seinen Verbindungen nur dann anwendbar ist, wenn unter Ausschluß des violetten und ultravioletten Anteils des Spektrums gearbeitet wird und der elementare Schwefel in seiner energieärmsten Form, also als S8-Molekel, vorliegt.
