Tolyltriazole(TTA) CAS 29385-43-1

Introduction

Tolyltriazole (TTA) is a mixture of 4-methylbenzotriazole and 5-methylbenzotriazole. The pure compound appears as yellowish-brown to light brown granules or beige pellets with a characteristic odor, and has a melting point of 76–87 °C. It is sparingly soluble in water (water solubility: g/100 mL at 18 °C), soluble in organic solvents such as alcohol, benzene, toluene, and chloroform, and soluble in dilute alkaline solutions. It readily absorbs moisture and is primarily used as a rust inhibitor and corrosion inhibitor for metals (such as silver, copper, lead, nickel, and zinc). It is widely used in rust-preventive oils (greases), circulating water treatment agents, automotive antifreeze, polymer stabilizers, and lubricant additives.

Applications:

Tolyltriazole (TTA) can be used as a corrosion inhibitor for non-ferrous copper and copper alloys, and also has a corrosion inhibition effect on ferrous metals. Copper corrosion inhibitor TTA is adsorbed on the metal surface to form a very thin film, protecting copper and other metals from corrosion by harmful media in the atmosphere and water. Copper corrosion inhibitor TTA forms a more uniform film, and the combined use effect is better when used with sodium mercaptobenzothiazole (MBT·Na) (CAS 2492-26-4).

Copper corrosion inhibitor TTA is dissolved in alcohol or alkali and added to the circulating water. The concentration of this product in the water is 2-10 mg/L. If the non-ferrous metals in the water system have been severely corroded, this product can be added at 5-10 times the normal concentration to quickly passivate the system.
