Dodecylamine (Laurylamine)
The C12 saturated fatty amine supplied by Chelora Chemicals — also known as laurylamine, a widely used mineral-flotation collector, corrosion inhibitor and quaternary-ammonium surfactant intermediate — exported from Indonesia as flake or molten solid with full batch documentation on every shipment.
What Dodecylamine (Laurylamine) is, and why buyers source it
A working overview of the compound's chemistry, its role as the shortest commercially common fatty amine, and the grades Chelora Chemicals keeps in regular supply.
Dodecylamine is a straight-chain, twelve-carbon (C12) primary fatty amine: a single reactive amine head attached to a saturated, fully hydrophobic lauryl tail. That head-and-tail structure is what gives all fatty amines their surfactant character, and dodecylamine's relatively short chain makes it noticeably more water-soluble and reactive than the longer C16–C18 fatty amines in the same family.
At room temperature it is a white to pale-yellow waxy solid or flake, melting at a modest temperature into a low-viscosity liquid that is handled molten in bulk dosing systems. It is only slightly soluble in water in its free-amine form but forms readily water-soluble salts with mineral and organic acids, the basis of most of its formulated uses.
Where it fits in the synthesis chain
Dodecylamine's largest use is as a flotation collector in mineral ore beneficiation, where its cationic amine salt selectively attaches to and floats non-sulfide minerals such as potash, silicate gangue and phosphate ores. It is also a widely used filming corrosion inhibitor for oilfield and refinery pipelines, and a key intermediate for quaternary ammonium surfactants used in fabric softeners and disinfectant formulations.
Grades we supply
Chelora Chemicals offers Dodecylamine in technical grade (≈95% assay, distilled fatty-amine cut) for flotation and corrosion-inhibitor use, and high-purity grade (99%+) for surfactant and quaternary-ammonium intermediate manufacture sensitive to colour and chain-length distribution. Both grades are supplied with a batch-wise certificate of analysis.
How Dodecylamine (Laurylamine) is made
An overview of the production route for orientation purposes. Our manufacturing partners' own process parameters and in-process controls are proprietary and are not disclosed beyond what is needed to interpret the certificate of analysis.
Dodecylamine is manufactured from lauric acid, the dominant fatty acid recovered from coconut or palm kernel oil. Lauric acid is first reacted with ammonia (ammoniation) and dehydrated to give lauronitrile (dodecanenitrile), which is then catalytically hydrogenated over a nickel- or cobalt-based catalyst, typically with excess ammonia present to favour the primary amine over secondary and tertiary by-products: lauric acid → lauronitrile → dodecylamine.
Why the nitrile-hydrogenation route from natural fatty acid is standard
Coconut and palm kernel oil are large-scale, renewable feedstocks that deliver lauric acid as their dominant fatty-acid fraction, making the ammoniation-dehydration-hydrogenation sequence a well-established, cost-effective route that is used across the whole family of natural-chain fatty amines, not just dodecylamine.
Industries and processes that use it
Dodecylamine is consumed across mineral flotation, corrosion-inhibitor formulation and surfactant manufacture, where its C12 amine head-and-tail structure is the main draw. The fields below account for most of the demand we see through our export desk.
Mineral Flotation Collector
Used as a cationic collector in froth flotation of non-sulfide ores such as potash, silicate gangue minerals and phosphate rock.
Corrosion Inhibitor (Filming Amine)
Forms a protective hydrophobic film on metal surfaces in oilfield, pipeline and refinery corrosion-control programmes.
Quaternary Ammonium Surfactant Intermediate
Quaternised to build cationic surfactants used in fabric softeners, hair-care conditioners and disinfectant formulations.
Asphalt & Epoxy Additive
Used as an anti-stripping additive in asphalt and as a fatty-amine curing agent component in epoxy formulations.
How the molecule is typically carried forward
The single reactive primary amine head, attached to a long hydrophobic tail, governs almost all of this molecule's further reaction chemistry. Reaction classes below account for most of the ways Dodecylamine is converted into a finished product or intermediate.
Salt Formation (Flotation Collector Activation)
Protonation with acetic or hydrochloric acid converts the free amine into its water-soluble, surface-active ammonium salt for use as a flotation collector.
Quaternisation
Reacts with an alkylating agent (e.g. methyl chloride, dimethyl sulfate) to form a permanently cationic quaternary ammonium surfactant.
Ethoxylation
Reacts with ethylene oxide to build nonionic/cationic ethoxylated fatty amine surfactants with tailored water solubility.
Amide/Imidazoline Formation
Condenses with fatty acids to build amide and imidazoline surfactants used in corrosion inhibitor and personal-care formulations.

This compound causes severe skin burns and eye damage, is harmful if swallowed or in contact with skin, and is very toxic to aquatic life with long-lasting effects. It must be handled with impervious gloves, splash-proof eye protection and suitable respiratory protection, particularly when molten, and must never be allowed to reach drains or waterways. Full first-aid, storage, spill and PPE guidance is in the MSDS issued with every shipment, and should be read in full before this material is handled.
Keeping it on spec between delivery and use
General storage guidance for this grade. Site-specific storage rules, segregation requirements and re-test intervals should follow your own EHS procedures and the MSDS issued with your batch.
Store in a cool, dry area away from strong oxidizing agents and strong acids, in tightly closed original packaging. If handled molten, maintain even heating to avoid localised degradation and colour development. If a batch is held past its retest date, re-check amine value, colour and melting point before use.
