OtherCpds =Benzimidazole Benzotriazole is an aromatic
azole containing two fused rings. Benzotriazoles are also a class of compounds containing the benzotriazole skeleton.Production
Benzotriazole is produced by reaction of
o-phenylenediamine ,sodium nitrite andacetic acid . [ [http://www.google.com/patents?id=CzICAAAAEBAJ U.S. Patent 4299965] ]Uses
Benzotriazole is a
complexing agent . It is used as acorrosion inhibitor , an aircraft deicer and anti-icer fluid as well as for silver protection indishwashing detergent s. Benzotriazole skeletons are found inpharmaceuticals such asantifungal ,antibacterial , andanthelmintic drugs.Environmental relevance
Benzotriazole is fairly well water-soluble, not readily degradable and has a limited sorption tendency. Hence, it is only partly removed in
wastewater treatment plant s and a substantial fraction reaches surface water like rivers and lakes. [W. Giger, C. Schaffner, HP. Kohler (2006): "Benzotriazole and Tolyltriazole as Aquatic Contaminants. 1. Input and Occurrence in Rivers and Lakes". Environ. Sci. Technol. 40,7186-7192. PMID 17180965]References
