Which solvent is used in 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.
Is benzotriazole an organic compound?
Benzotriazoles (BZTs) are a class of organic compounds that have been used as metal anticorrosive and ultraviolet stabilizer additives in a wide range of commercial and industrial applications.
What is the key reaction which is giving benzotriazole in final step?
1. o-Phenylenediamine on treatment with NaNO2 in acetic acid undergoes intramolecular cyclization to yield benzotriazoles.
What is the molecular formula of benzotriazole?
Benzotriazole (BTA) is a heterocyclic compound containing three nitrogen atoms, with the chemical formula C6H5N3. This aromatic compound is colorless and polar and can be used in various fields.
Which heterocyclic ring is present in Benzotriazole?
Abstract. Benzotriazole is a bicyclic heterocyclic system consisting of three nitrogen atoms and fused benzene ring, shows wide range of biological and pharmacological activities. Benzotriazole can be synthesized using benzene-1,2-diamine and carboxylic acid.
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.
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.
What is the category of benzotriazole?
Azoles. Heterocyclic compounds with 2 rings.
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.
What is the theoretical yield of benzotriazole?
The yield is about 8 g (67%). The benzotriazole crystallises much more readily from benzene (55 ml) but the material is still slightly coloured. A pure white product can be obtained by sublimation at 90-95 °C at 0.2 mmHg.
How is benzotriazole soluble in water and oil?
The solubility of water and oil determines that benzotriazole must have a high content of impurities and less water to achieve both water and oil. 1 2 3 benzotriazole is not only water-soluble but also oil soluble. The emulsifier is not required for the addition process. This can greatly reduce the side effects of the addition of benzotriazole.
Which is the chemical formula for benzotriazole 95-14n3?

Which is the simplest member of the benzotriazole family?
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. 1,2,3-benzotriazole appears as white to light tan crystals or white powder. No odor.
What is the role of 5 methyl 1H benzotriazole?
5-methyl-1H-benzotriazole is a member of the class of benzotriazoles that is 1H-benzotriazole substituted by a methyl group at position 5. It has a role as a xenobiotic and an environmental contaminant.
