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.

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.

How do you make 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.

Is benzotriazole an acid?

3 Benzotriazole. 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. ... Benzotriazole is a very weak base with a pK_a of 8.2, but NH is more acidic than indazole, benzimidazole, and 1,2,3-triazoles.

Is benzotriazole organic?

Benzotriazoles are organic compounds that have been used in a wide range of commercial and industrial applications.

Which is corrosion inhibitor?

A corrosion inhibitor is a chemical compound that, when added to a liquid or gas, decreases the corrosion rate of a material, typically a metal or an alloy, that comes into contact with the fluid.

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.

What is the molecular formula of benzotriazole?

What is the role of activated charcoal during re crystallization?

Activated charcoal is sometimes used to remove small amounts of colored impurities from solution. Activated charcoal has a high affinity for conjugated compounds, whose flat structures wedge themselves well between the graphene sheets.

What is recrystallization technique?

Recrystallization is a technique used to purify solid compounds. ... During recrystallization, an impure solid compound is dissolved in a hot liquid until the solution is saturated, and then the liquid is allowed to cool. ². The compound should then form relatively pure crystals.

Which acid is used in synthesis of benzimidazole?

Synthesis of benzimidazoles has been developed by the o-phenylenediamine with aldehydes using boric acid an efficient catalyst under mild reaction conditions in aqueous media.

What is rust inhibitor used for?

A rust inhibitor is a type of corrosion inhibitor designed to slow down the oxidization process in metals which have been exposed to oxygen and water and begun to rust.

What is the uses of corrosion inhibitor?

Corrosion Inhibitors are used to stop rusting and anodic corrosion of metals. This is generally done via the coating of the metal surface with a chromate layer. Oxygen scavengers can be used as CIs to react with dissolved oxygen in the environment and can help in preventing cathodic corrosion.

How do you make benzimidazole?

Preparation. Benzimidazole is produced by condensation of o-phenylenediamine with formic acid, or the equivalent trimethyl orthoformate: C₆H₄(NH₂)₂ + HC(OCH₃)₃ → C₆H₄N(NH)CH + 3 CH₃OH. 2-substituted derivatives are obtained when the condensation is conducted with aldehydes in place of formic acid, followed by oxidation ...
