Reactions in which Thionyl chloride is involved

  • SeO2 + 2SCl2O "75-90^oC"--> SeCl4 + 2SO2"|^"
  • H2O + SOCl2 -> SO2 + 2HCl
  • {R}/`|O|\OH + Cl\S|O`|/Cl -> {R}/`|O|\Cl + SO2 + HCl , where R = H H3C H3C\
  • {R}-OH + SOCl2 -> {R}-Cl + SO2 + HCl , where R = H3C H3C-CH2 CH3-CH2-CH2 `/`=`\//-\\
  • 2S + O2 + 2Cl2 "180-200^oC"--> 2SOCl2
