Chemical Properties

yellow to beige solid or Colorless needle-like crystals. Slightly soluble in cold water, ethanol and ether.


1H-Benzotriazole is an anticorrosive agent, which is useful in aircraft deicing and antifreeze fluids. It is also employed in dishwasher detergents. Further, it is used as a restrainer in photographic emulsions and also useful as a reagent for the determination of silver in analytical chemistry. It also serves as a corrosion inhibitor in the atmosphere and underwater. Further, it is utilized in the synthesis of amines from glyoxal.


ChEBI: 1H-Benzotriazole is the simplest member of the class of benzotriazoles that consists of a benzene nucleus fused to a 1H-1,2,3-triazole ring. It has a role as an environmental contaminant and a xenobiotic.


1H-Benzotriazole is prepared by the reaction of o-phenylenediamine with nitrous acid in dilute sulfuric acid. Damschrodner and Peterson were able to synthesize the 1H-benzotriazole in a high yield (80%) by nitrosation of o-phenylenediamine with sodium nitrite in glacial acetic acid and water.
Synthesis of 1H-benzotriazole via diazotization of o-phenylenediamine
Synthesis of 1H-benzotriazole via diazotization of o-phenylenediamine
Reaction: Add o-phenylenediamine to 50°C water to dissolve, then add glacial acetic acid, cool down to 5°C, add sodium nitrite to stir the reaction. The reactant gradually turned dark green, the temperature rose to 70-80 ℃, the solution turned orange-red, placed at room temperature for 2 hours, cooled, filtered out the crystals, washed with ice water, dried to obtain the crude product, the crude product was distilled under reduced pressure, and collected 201 -204°C (2.0kPa) fraction, and then recrystallized with benzene to obtain 1H-Benzotriazole products with a melting point of 96-97°C, with a yield of about 80%.


1H-Benzotriazole (BT) is a chemical used in a wide variety of industrial, commercial, and consumer products. It main used as an anticorrosive in metalworking, in art restoration, and as a tarnish remover and protective coating in the construction industry.
In the aircraft industry, 1H-benzotriazole and tolyl benzotriazole are found to be the primary agents in most types of aircraft deicing/antiicing fluid (ADAFs).
Benzotriazole is also used as a component of aircraft deicing fluid, pickling inhibitor in boiler scale removal, restrainer, developer and antifogging agent in photographic emulsions, corrosion inhibitor for copper, chemical intermediate for dyes, in pharmaceuticals, and as fungicide. (HSDB 1998).
Benzotriazole(BTA), ethylenediamine tetraaceticacid(EDTA), and potassium iodide(KI) were used for preparing the polishing slurries
