The Uses of Tetramethylammonium hydroxide pentahydrate
Tetramethylammonium hydroxide pentahydrate has been used in a study to assess strains of Pseudomnas species by a single-step gas chromatographic characterization procedure. It has also been used in a study to investigate solid-state metal hydride batteries nickel oxyhydroxide-metal hydride and manganese dioxide-metal hydride.
The Uses of Tetramethylammonium hydroxide pentahydrate
Tetramethylammonium Hydroxide Pentahydrate is a useful compound for preparing gamma-cesium lead iodide films for high-efficiency deep-red light-emitting devices.
The Uses of Tetramethylammonium hydroxide pentahydrate
Tetramethylammonium hydroxide pentahydrate is a clathrate hydrate, which shows high proton conductivity. It can readily uptake carbon dioxide. It is a promising candidate for energy devices, gas separation, and gas storage applications.
Tetramethylammonium hydroxide pentahydrate may be used in the preparation of a mesoporous molecular sieve belonging to the MCM-41 (mobil composition of matter No. 41) category with silica to (tetrahedral) aluminum ratio as low as 8.5:1.
General Description
Tetramethylammonium hydroxide pentahydrate is a clathrate hydrate, which shows high proton conductivity. It can readily uptake carbon dioxide. It is a promising candidate for energy devices, gas separation, and gas storage applications.
Purification Methods
It is freed from chloride ions by passage through an ion-exchange column (e.g. Amberlite IRA-400, prepared in its OH-form by passing 2M NaOH until the effluent is free from chloride ions, then washed with distilled H2O until neutral). A modification, to obtain carbonate-free hydroxide, uses the method of Davies and Nancollas [Nature 165 237 1950]. [Beilstein 4 IV 145.]
