SO2Cl2? | |||||||
would reacting Cl2 with sulfur dioxide (in the gas phase, with possible need for UV) yield SO2Cl2? (the more highly oxidized analog of thionyl chloride) |

Sulfuryl Chloride | |||||||
From the Merck Index: Monograph number: 9153 Title: Sulfuryl Chloride. CAS Registry number: [7791-25-5] Molecular formula: Cl2O2S Molecular weight: 134.97 Composition: Cl 52.53%, O 23.71%, S 23.76%. Line formula: SO2Cl2. Literature references: Prepd by passing a mixture of dry sulfur dioxide and chlorine through activated charcoal (other catalysts, such as camphor, can be used): Danneel, Angew. Chem. 39, 1553 (1926); Durrans, J. Soc. Chem. Ind. 45, 347 (1926); Meyer, Angew. Chem. 44, 41 (1931); Danneel, Hesse, Z. Anorg. Allgem. Chem. 212, 214 (1933); Allen, Maxson, Inorg. Syn. 1, 114 (1939). Properties: Colorless, mobile liquid, very pungent odor. Even the vapors are corrosive to human skin and mucous membranes. Turns yellow upon prolonged standing because of slight dissociation into SO2 and Cl2. d420 1.6674. d40 1.7045. mp -54.1 deg (also given as -46 deg). bp 69.3 deg. nD20 1.4437. Dipole moment 1.86. Trouton constant 20.7. Slowly dec by water, forming H2SO4 and HCl. With ice-cold water it forms a hydrate, SO2Cl2.15H2O, resembling camphor in appearance. Violent reaction on contact with alkalies. Miscible with benzene, toluene, ether, glacial acetic acid, other organic solvents. Melting point: -54.1; -46 Boiling point: 69.3 Density: 1.6674; 1.7045 Refraction: 1.4437 USE: Chlorinating and sulfonating or chlorosulfonating agent in organic syntheses, e.g., in the manufacture of chlorophenol and chlorothymol. Has been used in war gas formulations. All those moments will be lost in time, like tears in rain. |

How can you easily tell SOCl2 and SO2Cl2 apart without distilling? I have an old greenish-yellow bottle which I am unsure of... The Hive - Clandestine Chemists Without Borders |

as far as a qualitative test all i can think of , is if you hydrate a small sample and its SOCl2 then all the HCl and H203S will boil away, if its the other you should have sulphuric acid remain after boiling. |

Melting Point | |||||||
The melting point of thionyl chloride is -104.5°C; trying to freeze a small sample in a test tube with dry ice/acetone seems to be the best course Chemistry is our Covalent Bond |

the credibility of the freezing point test... | |||||||
the validity of the freezing point test would depend on wether or not his unknown is dissolved in ether or is free. but if it is in a free state then indeed a freezing point test would be good. |

so if one were to attempt this synth by passing dry S02 and Cl2 over activated charcoal, would the tube containing the activated charcoal have to be heated by say a bunsen burner during the reaction? id assume you would want to setup your gas generators so that that the molar rates of emission of S02 and Cl2 were equal? |

SO2 + Cl2 --> SO2Cl2 looks easy (camphor--> 20°C) but does it react with water like this: SO2Cl2 + 2 H2O --> H2SO4 + 2 HCl or like that: SO2Cl2 + 10H2O --> H2SO4 + 2 HCl + 8 H2O in other words is oleum obtained or not (i mean HCl/H2SO4) ???? other way to ask the question: If 2moles SO2Cl2 and 1 mole H2O are mixed, will some HCl gaz be formed or diluted HCl only ? |

I founded on some MSDS about SO2Cl2 that SO2Cl2 + (2+n)H2O --> H2SO4 + 2HCl + nH2O because SO2Cl2 + H2O --> 2HCl + SO3 so if it is true, it means that if 2mol of SO2Cl2 is mixed with 3mol of H2O oleum is obtained (2 SO2Cl2 + 2 H2O --> 4HCl + 2SO3 SO3 + H2O --> H2SO4 H2SO4 + SO3 --> HSO4- HSO3+ (oleum) or with one or two or more moles of H2O this super concentrated Acid is obtained: HSO4HSO3 + n H3OCl this looks like a super easy synthesis of oleum and HCl oleum... if some1 wants to try i founded that SO3 is reacting very easyly with H2SO4 20% or more, but not so easyly with H2O... so mixing 2mol of SO2Cl2 with 3-4mol of 30%H2SO4 (mol of H2O) could be the best... |
