Using Procedure

<p>

<p>
<strong><em><span style="font-family: georgia, serif;"><span style="font-size: 14px;">Tetrapropylammonium hydroxide, a quaternary ammonium compound, is mainly used as a structure directing agent for the preparation of molecular sieves and zeolites.</span></span></em></strong></p>

Note

<strong><em><span style="font-family: georgia, serif;"><span style="font-size: 14px;">Tetramethylammonium chloride is one of the simplest quaternary ammonium salts, with four methyl groups tetrahedrally attached to the central N. The chemical formula (CH3)4N+Cl− is often abbreviated further as Me4N+Cl−. It is a hygroscopic colourless solid that is soluble in water and polar organic solvents. Tetramethylammonium chloride is a major industrial chemical, being used widely as a chemical reagent and also as a low-residue bactericide in such processes as hydrofracking. In the laboratory, it has fewer synthetic chemical applications than quaternary ammonium salts containing longer N-alkyl substituents, which are used extensively as phase-transfer catalysts.</span></span></em></strong></div>
