Uses

(1-Decyl)trimethylammonium bromide is used in high performance liquid chromatography and in nuclear magnetic resonance. It is an important raw material and intermediate used in organic synthesis, pharmaceuticals and agrochemicals.

Definition

ChEBI: A quarternary ammonium salt whose basic unit comprises a decyltrimethylammonium cation and a bromide anion.

Purification Methods

Crystallise the salt from 50% (v/v) EtOH/Et2O, or from acetone and wash with ether. Dry it under vacuum at 60o. Also recrystallise it from EtOH and dry it over silica gel. [McDonnell & Kraus J Am Chem Soc 73 2170 1952, Dearden & Wooley J Phys Chem 91 2404 1987, Beilstein 4 IV 784.]

Synthesis, characterization and conductivity of quaternary nitrogen surfactants modified by the addition of a hydroxymethyl substructure on the head group

Two novel series of hydroxymethyl group-appended quaternary nitrogen surfactants (QNSs) based on the aliphatic N-alkyl-trimethylammonium and aromatic N-alkylpyridinium head groups were synthesized from the appropriate nitrogen head group precursor and 1-bromoalkane. The QNSs were characterized using 1H and 13C nuclear magnetic resonance and infrared spectroscopy, and their purity confirmed using elemental analysis. The solution behavior of the QNSs was investigated by conductivity, assessing both the aggregation concentration as well as the amount of counter-ion dissociation. The results showed a general decrease in the aggregation concentration for the compounds with the hydroxymethyl addition, where the pyridinium compounds were more affected than the ammonium QNSs. In contrast, the extent of counter-ion dissociation (α) from the aggregate was slightly increased for the ammonium compounds but that of the pyridinium compounds was not generally affected by the structural modification.
