Aloxime®840 is a high viscosity liquid product, which has a molecular weight of 277. This
water insoluble chelating reagent has exceptional good solubility in most commercial organic
solvents. Aloxime®840 also has a unique ability to form organically soluble complexes with
wide variety of metallic cations.

CHELATING REACTIONS:
Aloxime®840 will chelate a wide variety of metallic cations. It is a hydrogen ion donor and
consequently its reaction with metallic cations may be compared to an ion exchange resin
system operating on a hydrogen ion cycle. An example of complexation with a metallic
cation is shown by the following equation:
[nRH]org + [M+n]aq

SOLUBILITY
Aloxime®840 has been tested at levels of 5, 10, and 25% (W/V) in the following solvents,
and has been found to be completely miscible in all cases:
Acetone
Toluene
Cyclohexane
Isopropyl Alcohol
Isodecyl Alcohol
Methylene Chloride
Ethanol (abs.)
Kerosene
Hexane
This broad solubility characteristic generally carries over to include the metallic cation
chelates as well.
SUGGESTED USES
Because the Aloxime® chelating reagents are relatively new to the chemical industry, not
many applications are commercially practiced at the present time. The chemistry of the
product does suggest its potential use in several interesting applications including:
•
•
•
•
•
•
•
Organic soluble metal chelation agent
Anti-oxidant or pro-oxidant agents
Homogeneous hydrogenation catalyst
Anti-static additive
Combustion aids
Flame retardants
Conductive plastics
