Usage

General Description

Chromium acetate is a compound of chromium and acetate, with the molecular formula Cr(CH3CO2)3. It is a blue-green crystalline solid, and is primarily used in the production of various chromium(III) compounds, which are widely used in the manufacture of pigments, tanning agents, and catalysts. Chromium acetate is also employed in the textile industry for dyeing and printing, as well as in the production of specialty papers and inks. Additionally, it is used as a mordant in the textile industry and as a corrosion inhibitor for aluminum. In the laboratory, it is often used as a catalyst for the oxidation of organic compounds. Despite its utility, chromium acetate is considered to be toxic and harmful if ingested or inhaled, and must be handled with caution.

Chromium(II) Complexes with Hydroxyethylidenediphosphonic Acid

The complex formation of chromium(II) with hydroxyethylidenediphosphonic acid (HEDP, H5L) in an aqueous solution is studied by spectrophotometry. The pH region is determined where the HEDP complexonates of chromium(II) are stable. The effect of pH on the complexation and the composition of the coordination sphere of the complex ions is shown. The optimum conditions for the practical application of HEDP as a stabilizing ligand are chosen. The instability constants for tetra-, tri-, di-, and monoprotonated and neutral chromium(II) hydroxyethylidenediphosphonate complexes were calculated, whose pK were found to be 1.21, 2.43, 6.87, 12.60, 19.40, respectively. A new complex of chromium(II), Na4[Cr(H2L)2 · 2H2O] · 4H2O, was isolated from a solution and characterized using elemental, IR spectroscopic, and thermographic analyses.

Catalyzed process for producing metal carboxylates for use as animal feed supplements

A catalyzed process is disclosed for producing a polyvalent metal C2 -C3 carboxylate having the formula M(CH3 (CH2)x COO--)y, wherein M is the polyvalent metal cation that is manganese (Mn+2), cobalt (Co+2), or chromium (Cr+3), x is zero or 1 and y is an integer equal to the cationic charge of M. The polyvalent metal C2 -C3 carboxylate is prepared by admixing (i) a dry polyvalent metal compound that is an oxide, hydroxide or carbonate of Mn+2, Co+3 or Cr+3, (ii) an anhydrous C2 -C3 carboxylic acid, and (iii) a catalytic agent at a relative molar ratio of about 1:2-10:0.01-3 in the absence of an added solvent or other diluent to form a reaction mixture. The reaction mixture is heated to complete the reaction, remove the produced water and about 80 percent of the unreacted carboxylic acid. The product in residual carboxylic acid is solidified, ground and the product is recovered. The metal carboxylates can be used as biologically available and economical sources of trace metal ions for supplementation in animal diets.

Preparation of an oxy-acetyl compound

This invention provides a process for producing an oxy-acetyl compound by carbonylating an oxy-methyl compound with carbon monoxide in the presence of a rhodium catalyst, an iodine compound, and a metallic accelerator, and also in the presence of at least one compound selected from the group consisting of boron compounds, bismuth compounds, and tertiary amide compounds in the reaction system. When at least one of the bismuth or boron compound is present in the reaction system, the carbonylation reaction can proceed without precipitation of any metallic accelerator.
