Usage

General Description

N-octadecyl-1,3,5-triazine-2,4,6-triamine, also known as OTTA, is a chemical compound that belongs to the family of triazine-based antirust agents. It is commonly used as a corrosion inhibitor for various metals and alloys, particularly in oil and gas production, petroleum refining, and water treatment processes. OTTA molecules possess a long hydrophobic alkyl chain (octadecyl) and multiple triamine functional groups, allowing them to form a protective film on metal surfaces by chemisorption. This film acts as a physical barrier between the metal and corrosive agents, effectively preventing corrosion and extending the lifespan of the metal components. Additionally, OTTA has been found to exhibit biocidal properties, making it useful in preventing microbial growth and biofilm formation in industrial systems.

Method for modifying 1,3,5-triazine derivatives

PCT No. PCT/JP96/03762 Sec. 371 Date Jun. 22, 1998 Sec. 102(e) Date Jun. 22, 1998 PCT Filed Dec. 24, 1996 PCT Pub. No. WO97/24338 PCT Pub. Date Jul. 10, 1997A method for modifying 1,3,5-triazine derivatives characterized by heating and reacting a 1,3,5-triazine derivatives having at least one amino or mono-substituted amino group on a carbon atom or atoms on its ring with an alcohol in the presence of a metal catalyst and a hydrogen atom to introduce an alkyl group or an alkenyl group into each amino or mono-substituted amino group; another method for modifying 1,3,5-triazine derivatives characterized by heating and reacting a 1,3,5-triazine derivatives having at least one amino or mono-substituted amino group on a carbon atom or atoms on its ring with a dihydric alcohol in the presence of a metal catalyst and a hydrogen atom to introduce an alkyl group having a hydroxyl group into each amino or mono-substituted amino group; and 1,3,5-triazine derivatives obtained by the methods. The various modified sustituted 1,3,5-triazine derivatives thus produced are generally obtained as a mixture. These derivatives can be isolated as compounds having high-purity by a normal separation method for organic compounds, and the compounds are usable in the various applications mentioned in the specification.
