| Benzyltrimethylammonium hydroxide Usage And Synthesis |
| Chemical Properties | CLEAR SLIGHTLY YELLOW SOLUTION | | Uses | Benzyltrimethylammonium hydroxide is used as a phase-transfer catalyst. It is also used in aldol condensation reactions and base-catalyzed dehydration reactions. Further, it serves as a strong organic base and used in Horner-Wadsworth-Emmons olefination reactions. In addition, it is an active component in the formulation, which is used in silicon wafer cleaning applications. | | Uses | Benzyltrimethylammonium hydroxide can be used:- As a base in the synthesis of activated ynesulfonamides and tertiary enesulfonamides.
- In the synthesis of 3-indolyl-3-hydroxy oxindoles by treating isatin with indole.
- As a precursor for the preparation of quaternary ammonium acetate, benzyltrimethylammonium acetate (NBz111AcO). NBz111AcO solution in DMSO can be used to dissolve cellulose.
| | Flammability and Explosibility | Notclassified | | Safety Profile | Poison by subcutaneous route. Astrong base. When heated to decomposition it emits toxicfumes of NH3 and NOx. | | Purification Methods | A 38% solution (as supplied) is decolorized (charcoal), then evaporated under reduced pressure to a syrup, with final drying at 75o/1mm pressure. The anhydrous base is obtained by prolonged drying over P2O5 in a vacuum desiccator. [Beilstein 12 IV 2162.] |
