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.

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.
