Solvay Process
In 1861, Belgian chemist Ernest Solvay developed the Solvay process, a more efficient method to convert sodium chloride to soda ash light. In the Solvay process, ammonia reacts with sodium chloride with the aid of calcium carbonate. Sodium bicarbonate is produced, and it is then heated and converted to soda ash light.
Hou Process
In 1930, Chinese chemist Hou Debang developed the Hou process. In this process, carbon dioxide is pumped through a saturated solution of sodium chloride and ammonia to form sodium bicarbonate. The precipitated sodium bicarbonate is then heated, yielding pure soda ash. The Hou process is a modified version of the Solvay process, and the commonly used method is still the Solvay process.
