What is benzotriazole used for?

What is benzotriazole used for?

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.

What is the standard state of benzotriazole at different temperatures?

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).?) Benzotriazole (BTA) is a heterocyclic compound containing three nitrogen atoms, with the chemical formula C 6 H 5 N 3. This aromatic compound is colorless and polar and can be used in various fields.

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.

How is benzotriazole made?

Benzotriazole can be prepared by treating o-phenylenediamine with nitrous acid (liberated during the reaction between sodium nitrite and acetic acid) to form mono-diazonium salt that follows spontaneous intramolecular cyclization reaction to produce benzotriazole.

Is benzotriazole aromatic?

Benzotriazole (BTA) is a heterocyclic compound with the chemical formula C6H5N3. It features a five-membered ring containing three nitrogen atoms. This white to light tan solid has a variety of uses, for instance, as a corrosion inhibitor for copper….Benzotriazole.

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.

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).

Which solvent is used for recrystallization of benzotriazole?

Preferably, the reaction temperature is between 70° C. and 190° C. Preferably, recrystallizing is performed using a recrystallization solvent that is selected from the group comprising methylene halide, N,N-dimethylformamide, alcohol of the alkyl group containing 1 to 5 carbon atoms and halobenzene.
