General description

Aluminum isopropoxide is a versatile andinexpensive Lewis acid catalyst and dehydrating agent widely used in the fieldof organic transformations, sol-gel processing, and rechargeable batteries.

Application

Aluminum isopropoxide can be used:
  • As a precursor to synthesize alumina nanoparticles and multimetallic oxides via sol-gel processing.
  • As a catalyst for various organic transformations such as Meerwein–Ponndorf–Verley–Oppenauer (MPVO) reactions and ring-opening polymerization of lactides and lactones.
  • As coating material to fabricate electrodes for lithium-ion batteries toenhance cycling stability and performance.
