Description and Uses

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.

A potential labelled nitrification inhibitor of urea fertilizer in agricultural soils.
