What is the category of benzotriazole?
What is the category 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.
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 starting material of benzotriazole?
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.
Where is benzotriazole used?
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 organic?
Benzotriazoles are organic compounds that have been used in a wide range of commercial and industrial applications.
What is melting point of benzotriazole?
212°F (100°C)
Benzotriazole/Melting point
What is the molecular formula of benzotriazole?
C6H5N3
Benzotriazole/Formula
What is the melting point of benzotriazole?
What does corrosion inhibitor do?
Corrosion inhibitors are chemical substances that, when added in small amounts to the environment in which a metal would corrode, will reduce, slow down or prevent corrosion of the metal.
Which solvent is used for recrystallization of benzotriazole?
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 flammable?
ICSC 1091 – BENZOTRIAZOLE. Combustible. Finely dispersed particles form explosive mixtures in air. NO open flames.
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.
Is the chemical formula for benzotriazole colorless?
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.
What can be used as a solvent for benzotriazole?
The latter can be dissolved in water or a solvent. The solvent may include ethanol, benzene, toluene, chloroform, and N N-dimethylformamide. In addition, the benzotriazole corrosion inhibitor is used for surface purification of silver, copper, and zinc in electroplating.
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.
How much Benzotriazole can you give to a Greenacres?
Acute oral toxicity was evaluated in groups of 5 male albino Greenacres rats administered, by gavage, benzotriazole at dose levels of 46.4, 100 and 215 mg/kg in a 10% (w/v) suspension, or 464, 1000 and 2150 mg/kg in a 50% suspension.
