What is Dioctyl Methylamine? Properties, Uses & Suppliers

Dioctyl methylamine (DOMA) is a branched tertiary amine widely used in industrial applications, particularly as an intermediate in quaternary ammonium compounds (quats), corrosion inhibitors, and specialty surfactants. With its unique chemical properties, DOMA plays a crucial role in oilfield chemicals, agrochemicals, and anticorrosion formulations.

Key Properties of Dioctyl Methylamine

Chemical Formula: C17H37N

Molecular Weight: ~255.5 g/mol

Appearance: Clear to pale yellow liquid

Solubility: Insoluble in water, soluble in organic solvents

Boiling Point: ~280-300°C

Stability: Stable under normal conditions but reacts with strong acids

DOMA is valued for its low toxicity, high thermal stability, and effectiveness as a precursor for surfactants like di hydrogenated tallow benzyl methyl ammonium chloride.

Industrial Uses of Dioctyl Methylamine

1.Surfactant & Quaternary Ammonium Compounds (Quats)

• Used in manufacturing hexadecyl trimethyl ammonium chloride (HTAC 1631), a cationic surfactant for disinfectants and fabric softeners.

• Also a key ingredient in coco dimethyl amine oxide, which enhances foam stability in personal care products.

2.Oilfield Chemicals

Acts as a corrosion inhibitor in drilling fluids, protecting metal surfaces from acidic degradation.

3.Agrochemicals

Improves the efficiency of pesticides by enhancing emulsification and surface penetration.

4.Specialty Chemical Synthesis

Used in producing amine derivatives like fatty acid amines for lubricants and coatings.
