Benzotriazole solid is available in granular, flake, powder and crystalline forms. The most product form used global is the granular benzotriazole. Opposed to tolyltriazole being a mixture of two isomers, benzotriazole is one isomer.
Benzotriazole (BTA) is a pure compound. Benzotriazole has relatively good water solubility. Benzotriazole is used as the solid dissolved in solvents or in water-based systems as the sodium or potassium salt solution. Benzotriazole has always been of high quality with only slight odor and color. Benzotriazole is the triazole with the highest vapor pressure and starts to sublime at higher temperatures which makes it suitable for vapor applications. Benzotriazole is available in a variety of forms. The basic raw material benzene or the derived ortho-phenylene diamine (OPD) fluctuates with the price of oil. Benzotriazole has a bp of 350 deg. C (204 deg C at 15 mm Hg) and a sublimation point of 200 deg C. The pKa Dissociation Constant is 8.37 and the pH in water is 5.5-6.0 with a solubility in water of 1.98 g/l @ 25 deg C.
