Industrial uses TBA is used as a solvent, an inhibitor in hydraulic fluids and a chemical intermediate.
Tributylamine is also used as a catalyst in a wide range of chemical reactions, as an insecticide, an emulsifying agent and in dental cements (HSDB 1988).
Purification Methods
Purify the amine by fractional distillation from sodium under reduced pressure.
Pegolotti and Young heated the amine overnight with an equal volume of acetic anhydride, in a steam bath.
The amine layer was separated and heated with water for 2hours on the steam bath (to hydrolyse any remaining acetic anhydride).
The solution was cooled, solid K2CO3 was added to neutralize any acetic acid that had been formed, and the amine was separated, dried (K2CO3) and distilled at 44mm pressure.
Davis and Nakshbendi treated the amine with one-eighth of its weight of benzenesulfonyl chloride in aqueous 15% NaOH at 0-5o.
The mixture was shaken intermittently and allowed to warm to room temperature.
After a day, the amine layer was washed with aqueous NaOH, then water and dried with KOH.
(This treatment removes primary and secondary amines.)
Tributylamine was further dried with CaH2 and distilled under vacuum.
Tributylamine appears as a pale yellow liquid with an ammonia-like odor.
Less dense than water.
Very irritating to skin, mucous membranes, and eyes.
May be toxic by skin absorption.
Low toxicity. Used as an inhibitor in hydraulic fluids.
Applications, Intermediate used in the production of: dyes pharmaceuticals catalyts crop protection agents, photographic chemicals, acid binders, oil industry.
Packaging, Available in bulk and drums.

Tributylamine is a tertiary amine which belongs to the class of trialkylamines.
Tributylamine is used as proton scavenger in a variety of chemical processes (API, AgChem, …) and to produce Quats (e.g. tributylmethyl and tetrabutyl ammonium bromide, chloride or bisulphate) which are used as phase transfer catalysts.
Tributylamine (TBA or T-n-BA) is available in two grades:
TBA normal and TBA +, a special high purity grade of TBA, for example for use as proton scavenger in API production.
Both qualities are available in bulk, drums and ISO-containers.
General Description
A pale yellow liquid with an ammonia-like odor.
Less dense than water.
Very irritating to skin, mucous membranes, and eyes.
May be toxic by skin absorption. Low toxicity.
Used as an inhibitor in hydraulic fluids.
Sources/Uses:
Used as a strong base anion exchanger, polymerization catalyst, acid acceptor, solvent, inhibitor in hydraulic fluids, chemical intermediate, insecticide, and emulsifying agent; [HSDB] Used to make agricultural chemicals, photographic chemicals, and pharmaceuticals;
An organic compound with molecular formula C12H27N, used as an intermediate in the manufacture of other chemical compounds and as a solvent and catalyst in organic synthesis and polymerization.
Extraction and representation
Tributyl amine can be prepared by alkylation of ammonia with butan-1-ol or butyl halides are prepared.
Properties
Tributylamine is a colorless, hygroscopic liquid with an ammonia- like odor.
Tributylamine is a base is, however, due to the relatively larger butyl sterically hindered stronger than the more commonly used triethylamine .
Safety-related parameters
Tributylamine forms flammable vapor-air mixtures at higher temperatures.
The compound has a flash point between 63 ° C and 66 ° C.
The explosion range is between 0.7% by volume (54 g / m 3 ) as the lower explosion limit (LEL) and 6.0% by volume (464 g / m 3 ) as the upper explosion limit (UEL).
The ignition temperature is 195 ° C.
The substance therefore falls into temperature class T4.
Usage
Tributylamine is used, among other things, as:
Intermediate product for the production of other chemical compounds such as B. for the production of tributylmethylammonium chloride (TBMAC, (C 4 H 9 ) 3 CH 3 NCl, CAS number:56375-79-2 ), tributylbenzylammonium chloride (BTBAC, C 19 H 34 ClN, CAS number:23616-79-7 ) and other tetrabutylammonium salts
Solvent and auxiliary material for the isolation and purification of drugs
Catalyst ( proton acceptor ) for organic syntheses and for polymerizations (e.g. for phenolic resins and polyurethanes )
Corrosion inhibitor in hydraulic fluids
