Air & Water Reactions
Dust may form an explosive mixture in air. Slightly soluble in water.
Benzotriazole (BT) is an anticorrosive agent well known for its use in aircraft deicing and antifreeze fluids but also used in dishwasher detergents.
ACUTE/CHRONIC HAZARDS: When heated to decomposition 1H-Benzotriazole emits toxic fumes. 1H-Benzotriazole can react violently during vacuum distillation.
yellow to beige solid
Flash point data are not available for 1H-Benzotriazole. 1H-Benzotriazole is probably combustible.
ChEBI: The simplest member of the class of benzotriazoles that consists of a benzene nucleus fused to a 1H-1,2,3-triazole ring.
White to light tan crystals or white powder. No odor.
1,2,3-Benzotriazole crystallises from toluene, CHCl3, Me2NCHO or a saturated aqueous solution, and is dried at room temperature or in a vacuum oven at 65o. Losses are less if the material is distilled in a vacuum. CAUTION: may EXPLODE during distillation; necessary precautions must be taken.

The triazoles are a group of highly explosive materials that are sensitive to heat, friction, and impact. Sensitivity varies with the type substitution to the triazole ring. Metal chelated and halogen substitution of the triazol ring make for a particularly heat sensitive material. Azido and nitro derivatives have been employed as high explosives. No matter the derivative these materials should be treated as explosives.
