n-Octylamine · 1-Aminooctane · octan-1-amine · ≥99% commercial, LR and AR grades
Octylamine is a straight-chain C8 primary amine — the point in the series where the molecule turns distinctly oily and surface-active while still handling as a free-flowing liquid. It is used in corrosion inhibitors, mineral flotation, fuel and lubricant additives and surfactants, and as an intermediate in agrochemical, pharmaceutical and rubber chemistry. Chelora Amines supplies it worldwide and across India, in UN-specification packaging with a batch-wise COA and SDS.

Octylamine, also written n-octylamine, 1-aminooctane or octan-1-amine, is a clear, colourless to pale yellow liquid with an ammoniacal odour. It boils at about 176 °C, freezes close to 0 °C, and is only slightly soluble in water — well under 1 g per litre — while mixing freely with alcohols, ethers and hydrocarbons.
Eight carbons is where the alkylamine series turns amphiphilic. The amino head adsorbs onto metal and mineral surfaces and the C8 tail makes that surface water-repellent, which is why octylamine and its salts work as corrosion inhibitors and flotation collectors. It is shorter and easier to handle than waxy fatty amines, yet far less volatile and water-soluble than Hexylamine.
It is produced by catalytic amination of 1-octanol with ammonia and hydrogen, or by hydrogenation of octanenitrile made from caprylic acid. Di-n-octylamine, residual octanol, chain homologues and water are controlled in the specification.

Octylamine is an unhindered primary amine whose uses are shaped by its amphiphilic character: it reacts like any strong primary amine, and its products inherit a hydrophobic C8 tail.
Neutralises fatty, phosphoric and naphthenic acids to octylammonium salts, the film-formers in many inhibitor packages.
acid + C₈H₁₇NH₂ → saltGives N-octyl amides with acid chlorides, anhydrides and esters for dispersants and intermediates.
RCOCl + C₈H₁₇NH₂ → amideCondenses with γ-butyrolactone to give N-octyl-2-pyrrolidone, a surface-active solvent.
GBL + C₈H₁₇NH₂ → NOPTakes up ethylene oxide to give ethoxylated octylamines used as emulsifiers and antistatic agents.
C₈H₁₇NH₂ + n EO → ethoxylateAdsorbs through the amino head onto metal and mineral surfaces — the basis of flotation and inhibitor films.

RCHO + C₈H₁₇NH₂ → imineAdds to carbon disulfide to give octyldithiocarbamates for rubber and lubricant-additive chemistry.
CS₂ + C₈H₁₇NH₂ → dithiocarbamateExhaustive alkylation leads to quaternary ammonium biocides and phase-transfer catalysts.
C₈H₁₇NH₂ + 3 RX → R₄N⁺Process notes. Octylamine freezes close to 0 °C and is toxic by skin contact. In cold climates keep drums above 10 °C or let them warm before use, dose into exothermic reactions with cooling, and keep transfers closed and under nitrogen.
Discuss your processOctylamine is made by catalytic amination or nitrile hydrogenation, and the route sets the impurity profile: higher amines from over-reaction, chain homologues from the feedstock, and residual alcohol from incomplete conversion.
1-Octanol, or octanenitrile made from caprylic (octanoic) acid, is fed with ammonia and hydrogen.
Over a nickel or cobalt catalyst at elevated temperature and pressure, the alcohol or nitrile is converted to the primary amine; excess ammonia suppresses secondary amine.
The reactor delivers octylamine with ammonia, water, residual octanol, di-n-octylamine and traces of C6 and C10 homologues.
Ammonia is recycled; water is split off and vacuum distillation takes a narrow primary-amine cut away from the lights and the di-octylamine bottoms.
Product is tested for assay, di-octylamine, octanol, homologues, water and colour, then filled under nitrogen into carboys, drums, totes or bulk containers.
Di-n-octylamine is the main by-product and the one that shifts surface-active performance, because a twin-tailed secondary amine behaves very differently at an interface. Feedstocks from natural caprylic acid can carry C6 and C10 homologues, which change the melting point and solubility of downstream salts.
Residual octanol is inert in most salt-forming work but competes in acylation and isocyanate steps. Where a registration dossier or a validated process names limits, send them with the enquiry and we will match the batch rather than send the standard cut.
Twelve months in sealed original packing, kept cool and out of sunlight, is the normal working figure. Octylamine freezes close to 0 °C, so drums stored outdoors in winter can arrive part-solid; warm them gently and mix before sampling — never with an open flame or steam lance.
Keep drums closed between draws, blanket tanks with nitrogen where you can, and re-check assay, water and colour before a critical batch from older stock. A retained sample of every batch is held here.

The C8 amines and their neighbours differ most in physical form and volatility. Straight or branched chain, and six, eight or twelve carbons, decide how a product handles and how its derivatives perform.

Octylamine is checked before dispatch and each consignment leaves with the paperwork your QC, stores and accounts teams need on day one.
The numbers on a Certificate of Analysis are only useful if you know how they were produced. These are the methods behind the figures on ours, and the checks worth repeating at your own goods-inward.
Separates the amine from related amines and residual solvents in one run, and gives both the assay and the impurity profile that matter to your reaction.
An independent check on total amine content, useful as a quick goods-inward confirmation before a drum is released to production.
Water determination, which matters wherever the next step is moisture sensitive or the amine feeds an anhydrous reaction.
A visual platinum–cobalt comparison. A rising colour value is the earliest sign that a pack has been exposed to air or held too long.
Fast confirmation of identity and strength, and a simple way to spot a wrong pack or a contaminated drum.
Gravimetric residue and trace metal checks, which matter for catalytic steps and regulated formulations.
A sample from every dispatched batch is held here, so a query months later can be settled against the original material.
The batch number on the label ties back to the COA, the test record and the supply lot, which is what your auditor will ask to see.
Where your customer or regulator needs an independent result, we can arrange analysis at a NABL-accredited laboratory before dispatch.
