Benzotriazole

Molecular Formula:C6H5N3 MW:119 MP:90-100oC

Chemical Name:1,2,3-Benzotriazole

Molecular Formula:C6H5N3

MW:119

MP:90-100oC

Specificication

Light brown to white crystalline powder. Melting point 90 ~ 100 , in 98 ~ 100 sublimation. Boiling point of 201 ~ 204 (2kPa). Soluble in hot water, methanol, acetone, ethyl ether and other organic solvents, slightly soluble in cold water. Aqueous solution weak acidity, pH value of 5.5 ~ 6.5. On acid-base, oxidation - reduction is stable when heated to 100 are stabilized. With alkali metal ions can generate a stable metal salts. By the o-phenylenediamine diazotization, cyclization obtained, but also by the o-nitrophenyl hydrazine and Benzimidazolone synthesis.

Uses

Widely used as copper, silver corrosion inhibitor of equipment for water quality stabilizer, anti-rust oil preparation, diazo dye used to prevent fading, as well as copper and copper alloy arts and crafts of the discoloration and deterioration, can also be used as a photo - Anti-gray anti-fog agents, etc. VCI synthesis.
