What is benzotriazole used for?
Benzotriazole is a specific corrosion inhibitor for copper and copper alloys. It is now widely used in industry to reduce the corrosion of these alloys under both atmospheric and immersed conditions.
Is benzotriazole hazardous?
According to a 1977 EPA report, benzotriazole is considered to be of very low toxicity and a low health hazard to humans.
How is benzotriazole made?
Benzotriazole is a bicyclic nitrogen heterocycle formed by the fusion of the benzene ring with the 4,5-positions or the “d” site of 1H-1,2,3-triazole.
Which two rings are present in the structure of benzotriazole?
Benzotriazole features two fused rings. Its five-membered ring can exist in tautomers A and B, and the derivatives of both tautomers, structures C and D, can also be produced.
Is benzotriazole water soluble?
Solubility: 1) Water: 1-5 g/l (at 23.7°C). Soluble in alcohol, benzene, toluene, chloroform, and dimethylformamide. 2) Water: <0.1 g/l (at 18°C).
What is the MP of benzotriazole?
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….1.3Crystal Structures.

Is benzotriazole soluble in water?
Is benzotriazole polar?
Polar benzotriazoles, including the basic benzotriazole and the methyl-, hydroxy- and chloro- derivatives, are used as corrosion inhibitors in antifreeze liquids, various industrial systems (cooling, braking, cutting and metal-working fluids), aircraft de-icing fluids and household dishwashing detergents [2,3,4].
What is the molecular formula of benzotriazole?
C6H5N3Benzotriazole / Formula
Benzotriazole (BTA) is a heterocyclic compound with the chemical formula C6H5N3. It features a five-membered ring containing three nitrogen atoms.
How do you mix benzotriazole?
it all dilutes in 100ml rubbing alcohol. Then, add water. Benzotriazole has a limited solubility in water (< 2% w/v at room temperature) and is usually mixed as a 1% solution.
Is benzotriazole flammable?
Combustible. Finely dispersed particles form explosive mixtures in air. NO open flames.
Benzotriazole has been known for its great versatility. It has already been used as a restrainer (or anti-fogging agent) in photographic emulsions or developing solutions, and as a reagent for the analytical determination of silver.
Is benzotriazole degradable in water?
The methodology is not only limited to heterocyclization but was also successful for polynuclear hydrocarbons of small carbocyclic systems. Benzotriazole is fairly water-soluble, not readily degradable and has a limited sorption tendency.
Is benzotriazole polar or nonpolar?
This aromatic compound is colorless and polar and can be used in various fields. Benzotriazole features two fused rings. Its five-membered ring can exist in tautomers A and B, and the derivatives of both tautomers, structures C and D also can be produced.
How do you make benzyne from benzotriazole?
The major product, 1-aminobenzotriazole, forms benzyne in an almost quantitative yield by oxidation with lead (IV) acetate, which rapidly dimerises to biphenylene in good yields. Benzotriazole has been known for its great versatility.
