    Description / Table of Contents: The product prepared following the method of GOEHRING and FELDMANN from H2S2O3 and S2Cl2 is not a „spectrum“ of different salts as stated by WEITZ and BECKER, but really K2S6O6, which is also prepared from H2S2O3 and HNO2. Tetrasulfane-disulfonate does not only exist in the neutral form K2S6O6, but also in a „acid“ form with a part of the potassium - nonstoichiometrically - replaced by H+. The two forms have different shape and X-ray spectra.
    Notes: Bei dem nach GOEHRING und FELDMANN aus H2S2O3 und S2Cl2 dargestellten Produkt handelt es sich nicht, wie von WEITZ und BECKER angegeben, um ein „Spektrum“ verschiedener Salze, sondern um einheitliches K2S6O6, wie es auch aus H2S2O3 und HNO2 erhalten wird. Tetrasulfan-disulfonat existiert neben der neutralen Form K2S6O6 noch in einer „saueren“ Form, bei der ein Teil des Kaliums - nichtstöchiometrisch - durch H+ ersetzt ist. Die beiden Formen unterscheiden sich in Aussehen und Röntgenspektrum voneinander.

    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 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 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.

    Description / Table of Contents: Reactions of elemental Sulfur with Halogenated MethanesAt 250°C a reaction between CCl4 and sulfur forms S2Cl2 and CS2 (besides small amounts of S3Cl2 and S4Cl2). CHCl3 and sulfur above 200°C under catalytic influence of AlCl3 are forming HCl, S2Cl2, and CS2; CH2Cl2 and sulfur also are reacting (with AlCl3 or AI as catalyst) to CS2 and HCl. Only at 345°C one gets,CS2, HCl, and H2S from CH3Cl and sulfur. At 160°C forms HBR,BR2, and CS2. Aluminium is necessary for the reaction of CH2Br2 at 250°C with sulfur, forming CS2 and HBr. A mixture of products (CS2,H2S, HBr, CH3SCH3, and (CH3)3SBr) results from CH3 Br and sulfur at 250°C. CH3I and sulfur produce CS2,I2, and H2S at 145°C. The same products are formed from CH2I2 and sulfur with aluminium as catalyst at 175°C.
    Notes: CCl4 reagiert bei 250°C mit Schwefel zu S2Cl2 und CS2 (neben wenig S3Cl2 und S4Cl2). Aus CHCl3 und Schwefel bilden sich oberhalb 200°C unter AlCl3-Katalyse HCl, S2Cl2 und Cs2. CH2Cl2 und Schwefel liefern (wieder mit AlCl3 bzw. auch Al) CS2 und HCl. CH3Cl reagiert mit Schwefel erst oberhalb 345°C zu CS2, HCl und H2S. CBr4erst ab 245°C mit Schwefel zu HBR, Br2un 1 CS2 umsetzt. CH2BR2 benötigt bei 250°C wieder Aluminium als Katalysator, um mit Schwefel CS2 und HBr zu bilden. CH3Br reagiert mit Schwefel bei 250° zu einem nicht genau definierten Produktgemisch aus CS2, H2S, HBr, Ch3SCH3 und (CH3)3 SBr. Aus CHI3 und Schwefel erhält man bei 145°C CS2,i2 undH2S, ebenso wie aus CH2I2 und Schwefel, allerdings nur unter Aluminiumkatalyse bei 175°C.
