Beschreibung

General description

Tetrapropylammonium hydroxide (TPAOH) is a simple, affordable, and readily available quaternary ammonium base mainly utilized as a structure-directing agent for producing zeolites. It is found to be a good precursor to synthesis nanotubes. TPAOH is used as surface-active agent, phase transfer catalyst in organic synthesis.[1]

Application

Tetrapropylammonium hydroxide is used as:

• Structure directing agent (SDA) in the synthesis of zeolite socony mobil-5 (Zeolite ZSM-5).
• A phase transfer catalyst in the methylation of phenoxy acids in a superheated water extract from sand and soil samples.[1]

Analysis Note

Assay (acidimetric): 38.0 - 42.0 %
Density (d 20 °C/ 4 °C): 0.998 - 1.010
