A.     How to produce NaHCO₃ in manufacturing?

        NaHCO₃ or baking soda can be produced:

1/ The reaction of crystalline ammonium hydrogen carbonate with the brine to precipitate crystals of the title compound:                  

NH₄HCO₃ + NaCl → NaHCO₃ + NH₄Cl

2/ One may also produce it by the reaction of carbon dioxide and ammonia with the brine to precipitate crystals of sodium bicarbonate, as in the Solvay method, the method of soda ash production:

NH₃ + CO₂ + H₂O + NaCl → NaHCO₃ + NH₄Cl

3/ An important process is washing of the raw sodium bicarbonate several times by a dilute aqueous soda (Na₂CO₃) solution, to remove other salts (NH₄Cl). During the washing (in a flow of CO₂), the two following reactions occur which prevent contamination and loss of the crystals:

Na₂CO₃ + 2NH₄Cl → (NH₄)₂CO₃ + 2NaCl

CO₂ + H₂O + Na₂CO₃ → 2NaHCO₃

B.     How to produce KHCO₃?

As this project mentioned before, KHCO₃ exists as one of components of coal ash. Coal ash is what is left over after coal is burned in power plants to generate electricity. According to American Coal Ash Association (ACAA), coal is expected to be a major source of energy far into the next century, thus the amount of ash will be increase per annum. ( In 2003, over 121 million tons of ash were generated.) With the development of technology nowadays, the separation of KHCO₃ from ash is definitely inconsiderable.

C.  Further research:

 This experiment have just tested the fire retardant characteristic of chemical paint in wood, hopefully in future we will not only evaluate on variety of materials including sheetrock, lath and plaster, concrete, sheet metal, tin, foam, foam composite panels as well as advanced materials such as fiberglass and carbon fiber but we are also continuously researching, inventing a completely stronger fire resistant paint which can withstand extremely high temperature in a long duration. As a result, this chemical paint will have a high level of fire protection to many industries such as construction, insulation and transportation (land, air, sea).
