Additives for water-based functional fluids |
摘要 |
Selected N-aminomethyl-triazoles and imidazoles are prepared by the Mannich reaction on benzotriazoles or benzimidazoles with formaldehyde and primary or secondary amines. The products consist mainly of the 1-isomers. The compounds are metal passivators and are used as additives for water-based functional fluids being in contact with metals. These compounds with polar substituents on the amino-group are especially useful in water-based fluids such as anti-freeze or metal-working fluids.
