1 3 5-Triazine Biocide, IR-Triazine

Production Info:

IR-Triazine is the IRO brand of a kind of 1 3 5-triazine. It has many synonyms. You can see them at the bottom of this page.

The main production process of IR-Triazine is to add ethanolamine after the preprocessed methanol. And stir for 2 hours. Then preserve the temperature for another 1 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 also called s-triazine, is an organic chemical compound with the formula (HCN)3. This kind 1 3 5-triazine (CAS 4719-04-4) is mainly used 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 a low H2S situation. The advantages include convenient operation, low cost, and less operation area.

This 1 3 5-Triazine-1 3 5(2H 4H 6H)-triethanol is suitable for offshore and onshore oilfield with a stricter requirement in space and investment.

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