What is Hydroxilamine Hydrochloride?

This chemical is a hydrochloric acid salt of hydroxylimine. It is a biological intermediate in the nitrification i.e the biological oxidation of ammonia with oxygen into nitrite and the anammox i.e biological oxidation of nitrite and ammonium into dinitrogen gas. These are essential in the nitrogen cycle in the soil and in the wastewater treatment plants. Its CAS number is 90717-16-1. This chemical is hygroscopic in nature and sensitive to prolonged exposure to air. You can see it gradually reacting with water.

What are the uses of Hydroxylimine Hydrochloride?

This chemical has the following uses:

  • This chemical is used in the preparation of oximes and hydroxamic acids from carboxylic acids, N- and O- substituted hydroxyamines, and addition reactions of carbon-carbon double bond.
  • In the process of acetyl bromide method of extracting lignin from lignocellulosic biomass, the hydroxylammonium chloride can be used for the removal of bromine and polybromide from the solution.
  • During the surface treatments, it is used to prepare anti-skinning agents, corrosion inhibitors, and cleaner additives.
  • It is also used as the initial material for the pharmaceuticals and agrochemicals manufacturing.
  • It acts as an antioxidant, vulcanization accelerator, and radical scavenger in the rubber and plastics industry.
  • For the textile dyes, it is used as a fixative, as an auxiliary in certain dyeing processes.
  • It is used as a metal extraction and floatation aid.
  • It is also used as an antioxidant in fatty acids and soaps, as a colour stabilizer and emulsion additive in the colour films.
  • In analytical chemistry, it is used in the analysis of iron in the water combination with α,α-dipyridyl. Here, the hydroxylammonium chloride converts all the iron into Fe2+, which then forms a coordination complex with the dipyridyl.
  • It is used as a fuel additive, processing aids that are specific to the petroleum industry.
