Description
Tolyltriazole is a water-stabilizing chemical that inhibits corrosion by bonding to metal parts and machinery surfaces to prevent water from destabilizing the molecular structure of the metal. It creates an electrochemical barrier that is thick enough to deter corrosive chemicals. This barrier is very durable and features favorable oxidative and thermal stability. The long-term protective barrier created by tolyl triazole does not contaminate process fluids or the metal material of piping systems. Like benzotriazole, another corrosion inhibitor, tolyltriazole contains an extra methyl group that makes it soluble in some organic solvents. It is especially well-suited for pure copper and copper alloys because it protects copper from galvanic corrosion when in contact with other metals. Tolyltriazole also protects cobalt, silver, and zinc. It may also shield aluminum and steel from corrosion if combined with other corrosion-inhibiting chemicals.
Chemical Properties
light brown powder or granules
Uses
A potential labelled nitrification inhibitor of urea fertilizer in agricultural soils.
Uses
Tolyltriazole acts as a corrosive inhibitor and is used as corrosion protection on top of metals such as copper.
Production Methods
In a process for the production of tolyltriazole comprising diazotizing
ortho-toluenediamine with a nitrite, the improvement wherein said
ortho-toluenediamine is treated by adding from 0.001 to 5% by weight,
based on 100% by weight of ortho-toluenediamine, of a compound selected
from the group consisting of aldehydes, ketones, acetals and ketals.
General Description
Tan to light brown granules or beige pellets with a characteristic odor.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Tolyltriazole is incompatible with oxidizing agents . Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Health Hazard
Acute/ Chronic hazards:When heated to decomposition this compound emits toxic fumes. It is an eye and lung irritant. (NTP, 1992).
Fire Hazard
Tolyltriazole is combustible.
