FAQ - Technical & Supply Chain

  • Q:

    What is Laurylamine Dipropylenediamine (CAS 2372-82-9) used for?

    A: Laurylamine Dipropylenediamine (CAS 2372-82-9, EINECS 219-145-8) is a functional aliphatic polyamine primarily used as an intermediate in the production of corrosion inhibitors for water treatment, oilfield chemical formulations, and industrial processing systems. Its diamine structure provides strong adsorption on metal surfaces and effective film-forming performance.
  • Q:

    How does Laurylamine Dipropylenediamine function as a corrosion inhibitor intermediate?

    A: The diamine structure provides multiple amine functional groups that adsorb onto metal surfaces, forming a protective film that reduces corrosion rates. This makes it a valuable intermediate for formulating corrosion inhibitor packages used in cooling water systems, oil well treatments, and industrial pipeline protection.
  • Q:

    What specifications are important when sourcing Laurylamine Dipropylenediamine?

    A: Key specifications include amine value, purity, water content, appearance, and density (0.880 g/cm³). Buyers should verify the amine value range, residual moisture limits, and whether the product meets the required grade for their specific inhibitor formulation or industrial application.
  • Q:

    What is the difference between Laurylamine Dipropylenediamine and monoamines like dodecylamine?

    A: Laurylamine Dipropylenediamine contains two propyleneamine groups, giving it higher amine functionality and stronger metal surface adsorption compared to monoamines like dodecylamine. This makes it more effective as a corrosion inhibitor intermediate while also offering greater reactivity for downstream chemical synthesis.
  • Q:

    Is Laurylamine Dipropylenediamine soluble in water and organic solvents?

    A: It has a water solubility of 190 g/L at 20 °C and organic solubility of 560 g/L in organic solvents at the same temperature. This balanced solubility profile makes it suitable for formulating both aqueous and solvent-based corrosion inhibitor systems.
  • Q:

    What quality indicators should buyers verify when sourcing Laurylamine Dipropylenediamine?

    A: Buyers should verify amine value, water content, appearance (clear liquid), density, and the presence of any impurities that could affect downstream corrosion inhibitor synthesis. COA, TDS, and SDS documentation should be reviewed to confirm product suitability for the intended application and compliance with handling requirements.
