| Tetramethylammonium bromide Usage And Synthesis |
| Chemical Properties | SLIGHTLY GREY CRYSTALLINE POWDER |
| Uses | Tetramethylammonium bromide acts as an ion pair reagent. It is used as a surface-active agent and an active ingredient for conditioners. Further, it is used as a softner for textiles and paper products. It is also employed as a disinfection agent, sanitizer, antimicrobial and antistatic agent. In addition to this, it plays in important role as a phase transfer catalyst in synthetic chemistry. |
| Uses | Tetrabutylammonium bromide (TBAB) may be used in the molten state in the following processes:
|
| Definition | ChEBI: The bromide salt of tetramethylammonium. |
| General Description | Tetrabutylammonium bromide is a quaternary ammonium compound that is widely used as a phase transfer catalyst. Absolute viscosities of its aqueous solutions have been measured at various temperatures (20,25 and 30°C). Various physical properties (activity coefficient up to saturation, conductance, density and solubility in water) of TMABr have been evaluated. |
| Purification Methods | Crystallise the bromide from EtOH, EtOH/diethyl ether, MeOH/acetone, water or from acetone/MeOH (4:1) by adding an equal volume of acetone. It is dried at 110o under reduced pressure or at 140o for 24hours. [Beilstein 4 IV 145.] |
