Preparation of washing soda by solvay’s process

  • The Solvay process is extensively used for industrial preparation of sodium carbonate (soda ash). The process is named after Ernest Solvay who developed the process during the 1860s.
  • Carbon dioxide reacts with the dissolved ammonia to form ammonium carbonate followed by ammonium hydrogen carbonate.

2NH3 +H2O + CO2→ (NH4)2CO3

(Ammonia)                 (Ammonium Carbonate)

(NH4)2CO3 + H2O + CO2 → NH4HCO3

(Ammonium Carbonate)       (Ammonium hydrogen carbonate)

NH4HCO3       +          NaCl → NH4Cl     +    NaHCO3

Sodium hydrogen carbonate crystal separates. These are heated to give sodium carbonate.

     2 NaHCO3→  Na2CO3 + CO2 + H2O

But this process cannot be used to prepare potassium due to the high solubility of potassium bicarbonate and hence difficult to be precipitated by adding ammonium bicarbonate to a saturated solution of potassium

β-Elimination (beta-elimination): A chemical reaction in which atoms or groups are lost from adjacent atoms, resulting in a new pi bond: A-B-C-D ---> A + B=C + D. One of atoms lost is usually (but not always) a proton. The new pi bond is usually (but not always) formed between two carbon atoms.
