Tetramethylanunonium hydroxide

In this case tetramethylanunonium hydroxide is preferred to sodium or potassium hydroxide as the base. Triton B is less satisfactory. ... 

Some bases, such as sodium hydroxide and tetramethylanunonium hydroxide, are used for sample dissolution, as are some reagents that are not acids or bases, like hydrogen peroxide. The chemical literature contains sample dissolution procedures for virtually every type of material kuown and should be consulted. For elements and inorganic compounds, the CRC Handbook of Chemistry and Physics gives guidelines for dissolution in the tables of physical properties of inorganic compounds. 

The diemicals used in the preparation of the titanates were tetraisopippyl dtanate, an aqueous solution of NaOH, a solution of tetramethylanunonium hydroxide in methanol, A1(N03)3 9H20, tetrtqnropylanunonium chloride, and teti ntyl ammonium chloride. These chemicals were mixed in an tq ropriate manner to produce in most cases a white precipitate. In some cases, depending on the solution composition, a ciystaUine titanate formed at room tenq)erature.
