What is sulfamic acid crystals used for?

Sulfamic Acid as a Cleaning Agent

Sulfamic acid is used as an acidic cleaning agent, usually for ceramics and metals. Over the last few years it has replaced hydrochloric acid as a remover of the rust. In homes, it is frequently found as a descaling agent in toilet cleaners, and detergents for the removing the lime scale. When compared to other strong and most common strong mineral acids, the amidosulfuric acid has the needed low toxicity, low volatility, and water descaling properties.

Industrial Applications of Sulfamic Acid

The sulfamates have been used in the design of various types of therapeutic agents such as nucleotide/nucleoside HIV, antibiotics, HIV protease inhibitors (PIs), weight loss drugs, antiepileptic drugs, and anticancer drugs. Sulfamic acid is also used as a chlorine stabilizer in cooling towers and swimming pools.

 

  • Paper & pulp Industry

Sulfamic Acid powder inhibits pulp degradation due to temperature at the hydrochloride and chlorination stage. It allows bleaching at elevated temperature and lower pH without any loss in strength.

 

  • Dyes & Pigments Industry

Sulfamic acid takes out excess of nitrides that are used in the diazotization reactions during the manufacturing of pigments and dye stuffs. It can also remove nitrides if present in process water of emissions.
