The process of achieving a bleaching effect involves the removal of chromophores. This can be accomplished by adsorbing the colored compounds onto active surfaces such as active carbon or bleaching clays.

The majority of potential pathways to obtain hydrazine are limited due to the availability of raw materials and production costs. Nitrogen and ammonia stand out as the only viable starting materials for a more straightforward process.

Acetaldehyde is produced from the following raw materials: ethanol obtained through the fermentation of carbohydrates or the hydration of ethylene, acetylene, ethylene, lower hydrocarbons, carbon monoxide and hydrogen and methanol.

They are employed in the production of synthesis gas and hydrogen, ammonia, methanol, and Fischer-Tropsch synthesis, in the transformation of hydrocarbons (epoxidation of ethylene and propene, ammoxidation of hydrocarbons, and hydroprocessing reactions), as environmental catalysts for catalytic reduction of nitrogen oxides from stationary sources, and in automotive exhaust catalysis.

Green ammonia is described as ammonia synthesized with essentially zero carbon ootprint. Green ammonia can be produced using conventional technology for the ammonia synthesis loop in combination with electrolysis-based hydrogen or using nonconventional technologies for ammonia synthesis.

Aliphatic amines are produced from alcohols, carbonyl compounds, nitriles, alkyl halides, nitro compounds and olefins. The production of amines involves different methods, each suited to specific raw materials and desired products.
