    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.
