General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. The iron catalysts are known to be inexpensive and environmentally benign. Click here for more information.

Application

Iron(II) chloride can be used to catalyze:
  • The preparation of Grignard compounds, such as 1-naphthylmagnesium chloride.
  • The selective oxidation of 2,4,6-trimethylphenol (2,4,6-TMP) to 3,5-dimethyl-4-hydroxybenzaldehyde (DMHB) in the presence of acetoxime.
  • Raney-type catalysts modified with FeCl2 show enhanced selective hydrogenation of an α,β-unsaturated aldehyde to an unsaturated alcohol.

Magnetite nanoparticles (MNPs) were prepared by alkaline hydrolysis of Fe(II) and Fe(III) chlorides. Adsorption of polyacrylic acid (PAA) on MNPs was measured at pH=6.5±0.3 and I=0.01 M (NaCl) to find the optimal PAA amount for MNP stabilization under physiological conditions.
