Production methodprocess:

Prior to join a certain amount of water in the reaction kettle, heating to 50 ℃. Then add 1 mol o-phenylendiamine, 2.01 mol, glacial acetic acid, stirring to dissolve after cooling to 0 ℃, add 1 mol, sodium nitrite. Drop is finished heats up to 73 ℃, reaction 2 h. Let stand for the night. Filter, filter cake washing twice, drying, crushing, sieving to finished products.


  1. Widely used for metal rust and corrosion inhibitor, used for the preparation of water quality stabilizer, anti-rust oil, also can be used as a photographic proof ash antifoggant, synthesis of the vapor phase rust inhibitor

  2. Used for industrial gear oil, hyperbolic gear oil extreme pressure, anti-wear hydraulic oil, the oil film bearing oil, grease and other lubricating grease, rust gas phase corrosion inhibitors

  3. For anti-rust oil (fat) in the products, many of vapor phase inhibitors used in copper and copper alloy circulating water treatment agent, automobile antifreeze, photographic antifoggant, polymer stabilizers, plant growth regulator, lubricating oil additives, uv absorber, etc. This product is compatible with a variety of scale inhibitors, algae fungicidal.

  4. Widely used in copper, silver equipment corrosion, rust. Can also be used for photographic grey, antifoggant, the preparation of vapor phase corrosion inhibitor.

  5. To surface purification in electroplating silver, copper, zinc, have its effect.
