Dodecyltrimethylammonium Bromide Chemical Properties,Usage,Production

Chemical Properties

white to slightly yellow powder

Uses

(1-Dodecyl)trimethylammonium bromide is used as a surfactant, as an emulsifier of rubber and asphalt and as an anti-static agent of synthetic fiber. It acts as an ionic surfactant and useful in the preparation of gold nanopartilces along with sodium dodecylsulfate. It is also used as paint strippers and foaming stabilizers. It is used to prepare dodecyltrimethylammonium bromide. By using conductimetry, density measurements, and small angle neutron scattering, it is used to study the micelle formation in water-dimethylsulfoxide mixture. Further, it is a useful biochemical for proteomics research.

Uses

Dodecyltrimethylammonium Bromide is a quaternary ammonium salt useful as paint strippers, foaming stabilizers, and bactericidal lotions.

Uses

Dodecyltrimethylammonium bromide has been used in a study to assess the distribution of binary mixed counterions in surfactant adsorbed films. It has also been used in a study to investigate chain length compatibility of surfactants for extraction of organophosphorous pesticides.

Definition

ChEBI: A quarternary ammonium cation having one dodecyl and three methyl substituents around the central nitrogen.

General Description

Dodecyltrimethylammonium bromide is a quaternary ammonium surfactant.

Flammability and Explosibility

Not classified

Purification Methods

Purify the salt by repeated crystallisation from acetone. Wash it with diethyl ether and dry it in a vacuum oven at 60o [Dearden & Wooley J Phys Chem 91 2404 1987]. [Beilstein 4 IV 798.]
