General description

Aluminum chloride hydrate is a highly reactive compound that has various applications in different fields. It is commonly used as a catalyst in chemical reactions, including the polymerization of olefins and the Friedel-Crafts reactions, and is known for its Lewis acid properties.

Application

Aluminum chloride hydrate can be used as a:
  • Precursor to synthesize high surface area alumina aerogels by sol-gel processing method.
  • Catalyst for Friedel-Crafts alkylation of indoles.
  • Dopant to synthesize Al-doped ZnO thin films by ultrasonic spray pyrolysis.
  • Starting material to synthesize Boehmite nanoparticles with controlledmorphology.
