How do you get Hydrogen or E949?

To obtain the additive E949, also known as nitrogen dioxide, a specific chemical process is carried out. Here I provide you with the general steps to obtain it

Collection of sulfur dioxide (SO2) Sulfur dioxide generated from industrial sources is collected, such as the burning of fossil fuels, mineral processing and chemical factories.

Oxidation of sulfur dioxide to sulfur trioxide (SO3) SO2 undergoes an oxidation reaction with oxygen to form SO

This reaction can be carried out at high temperature and with suitable catalysts.

Absorption of sulfur trioxide in water The SO3 resulting from the previous stage is passed through an aqueous solution to absorb the compound and form sulfuric acid (H2SO4).

Neutralization of sulfuric acid with ammonium carbonate Ammonium carbonate (NH4)2CO3 is added to the sulfuric acid obtained in the previous step, which gives rise to a neutralization reaction that produces ammonium sulfate ((NH4 )2SO4).

Decarbonation of ammonium sulfate Ammonium sulfate undergoes a heat process to eliminate the carbon present in the molecule, resulting in the formation of nitrogen dioxide (NO2). This is the general process to obtain the additive E94

However, it is important to note that this additive is mainly used as a propellant in aerosols and has been the subject of debate due to its effects on health and the environment. Therefore, it is recommended to follow relevant regulations and restrictions regarding its production and use.
