The catalytic reaction mechanisms of cobalt and the iron-complex driers have been shown to be the same, however the efficiency of the iron-complex drier is so high that less oxygen is needed to promote oxidative cure throughout the film, not just on the surface as do the cobalt carboxylates
In that way, carboxylate
has been identified as the group mainly responsible for chelation between humic substances and metallic ions (Holman et al.
The deposits that formed at the inlet of the capillary tube of the R-134a/POE systems (least soluble) contained copper and iron carboxylates
(carboxylic acids from brazing flux, POE hydrolysis, ester manufacturing oils, etc.
In the first set of paints, the dispersant level was kept at 1% of pigment solids as the % of carboxylate
in the dispersant was varied.
also use the Lewis acid mechanism but can utilize an insertion mechanism as well, he said.
Vibrational stretching frequencies of the carboxylates
coordinated to the zinc metal ion appear in the range 1750-1380 [cm.
It offers customers the ability to deal proactively with the potential hazard classification of cobalt carboxylate
Reedijk, Dinuclear Paddle-Wheel Copper(II) Carboxylates
in the Catalytic Oxidation of Carboxylic Acids.
The difference in energy between the symmetric and asymmetric carboxylate
stretches can be used to establish the coordination mode of the carboxylates
(Deacon and Phillips, 1980) and is approximately 160 [cm.
OMG Americas has announced the promotion of David Holdsworth to business manager, metal carboxylates

would explain the high solubility--and therefore the long lifetime in water-of the organic hydrocarbons, Gaffney asserts.
