Product Description
1H-Benzotriazole is synthesized via the reaction of o-phenylenediamine with nitrous acid in dilute sulfuric acid. Damschrodner and Peterson successfully achieved a high yield of 80% by performing the nitrosation of o-phenylenediamine with sodium nitrite in a mixed solvent system consisting of glacial acetic acid and water.
As a high-efficiency anticorrosive agent, 1H-Benzotriazole is widely incorporated into aircraft deicing fluids and antifreeze solutions. It is also applicable to dishwasher detergent formulations and serves as a restrainer in photographic emulsions, as well as an analytical reagent for silver content determination. Furthermore, it offers reliable corrosion protection under both atmospheric and underwater conditions, and acts as a key material for the synthesis of amines derived from glyoxal.
