(redirected from carboxylates)
Also found in: Dictionary, Thesaurus.


A salt or ester of an organic acid, derived from the carboxyl group. Soaps, which are usually the sodium or potassium salts of fatty acids, are carboxylates.
adj. (-lāt′, -lĭt)
1. Of or relating to a carboxylate.
2. Of or relating to the anionic conjugate base of a carboxylic acid, specifically the CO22- group

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.

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.
Metal carboxylates also use the Lewis acid mechanism but can utilize an insertion mechanism as well, he said.
