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

Our aim was to assess the spatiotemporal evolution of the cerebrovascular inflammation occurring after ischemic and hemorrhagic strokes using a recently developed, fast, and ultra-sensitive molecular MRI method. We first assessed longitudinally the cerebrovascular inflammation triggered by collagenase-induced hemorrhage and

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.
