We present methodologies to functionalize iron oxide (Fe3O4) nanoparticles with biosurfactants and biocompatibility results. Positively charged Fe3O4 nanoparticles of average hydrodynamic size -26 nm is functionalized with four different molecules of interest, viz., surfactin, rhamnolipid, polyethylene glycol (PEG) and dextran.

Production of anilines--key intermediates for the fine chemical, agrochemical, and pharmaceutical industries--relies on precious metal catalysts that selectively hydrogenate aryl nitro groups in the presence of other easily reducible functionalities. Herein, we report convenient and stable iron oxide (Fe2O3)-based catalysts

Questions

1–2 of 2 Questions  
  1. Product 720704 is a dispersion of iron(III) oxide particles in water. Is there also a dispersant present? If so, what is the structure of the dispersant?

    1 answer
    1. The dispersant is an ethoxylated carboxylic acid. Please see the structure in the attached pdf file. The carboxylic acid is esterified, so the terminus, as shown, is an alcohol.
