IR-Triazine (Grotan BK Equivalent)

Production Info

The main production process of Grotan BK is to add ethanolamine after the preprocessed methanol and stir for two hours. Then to preserve the temperature for another one hour. Terminator is properly added to prevent the side reaction. The solution is filtrated after being settled, then concentrated with some auxiliaries.


CAS No.: 4719-04-4

EC No.: 225-208-0

Molecular Formula: C9H21N3O3

Structural Formula

1-3-5 Triazine



IR-Triazine is a good equivalent of Grotan BK. This Grotan BK equivalent is usually mostly applied as desulfurizer and anti-mildew agent.

As desulfurizer, IR-Triazine is mainly to remove the H2S generated from the exploitation of crude oil and natural gas, thus guaranteeing the health in the production field and reducing the H2S corrosion to equipment.

By injecting into the desulfuration process, IR-Triazine has the following advantages in low H2S situation: convenient operation, low cost, and less operation area. It is suitable for offshore and onshore oilfield with stricter requirements in space and investment.

Being an anti-mildew agent, IR-Triazine is definitely the main ingredient of Grotan BK. This Grotan BK is widely used in metal processing (cutting and grinding fluid), papermaking (paper coating), painting and coating, electroplating and leather (lustering agent).


AppearanceColorless or light yellow transparent liquid
Active acid (by titration) %74-78
Refractive Index1.47-1.49
pH(as it)9.0-12.0

As desulfurizer, IR-Triazine can be directly put into the desulfurization process. For high-sulfur crude, the advised the amount to use is 0.3-0.5%.

Being an anti-mildew agent, the dosage depends upon the situation using the following reference.

Metal Processing0.15-0.3%
Painting and Coating0.2%
