:2 Cl2 + 2 Na2CO3 + H2O → Cl2O + 2 NaHCO3 + 2 NaCl:2 Cl2 + 2 NaHCO3 → Cl2O + 2 CO2 + 2 NaCl + H2Oيمكن أن يتم هذا التفاعل بدون ماء ولكنه سيحتاج إلى التسخين إلى 150-200 °س.
:2 Cl2 + 2 Na2CO3 + H2O → Cl2O + 2 NaHCO3 + 2 NaCl:2 Cl2 + 2 NaHCO3 → Cl2O + 2 CO2 + 2 NaCl + H2OThis reaction can be performed in the absence of water but requires heating to 150-200°C; as dichlorine monoxide is unstable at these temperatures it must therefore be continuously removed to prevent thermal decomposition.
