Macromolecular metal carboxylates

Russian Chemical Reviews, 2008
Data on the synthesis and physicochemical studies of salts of mono- or dibasic unsaturated carboxylic acids and unsaturated metal oxo-carboxylates are generalised and described systematically. The structures and properties of the COO group in various compounds and characteristic features of the structures of carboxylate complexes are analysed. The main

Discovery and development of microporous metal carboxylates

The Chemical Record, 2005
AbstractWe have found a form of copper(II) terephthalate that occluded an enormous amount of gases such as N2, Ar, O2, and Xe. Copper(II) terephthalate is the first metal complex found capable of adsorbing gases. This complex has opened a new field of adsorbent chemistry and is recognized as a leader in the construction of microporous metal complexes ...

Carboxylic acids as metal extractants

Talanta, 1974
One of the problems in the extraction of trace elements is that matrix elements must usually be masked, involving the addition of large amounts of extra reagent and thus increasing the risk of contamination. If the maxtrix element is to be removed, an extraction system of high capacity is needed to avoid dilution effects. In this respect, long-chain or

Metal-carboxylic Acids and Their Derivatives

Russian Chemical Reviews, 1988
Questions connected with the synthesis of metal-carboxylic acids, compounds incorporating [M]–COOH fragments with a metal–carbon bond in which M is a transition metal complex, and their derivatives (salts, esters, and amides) are considered. The bibliography includes 189 references.

Microporous Materials of Metal Carboxylates

Journal of Solid State Chemistry, 2000
Copper(II) terephthalate absorbs a large amount of gases such as N2, Ar, O2, and Xe. The maximum amounts of absorption of gases were 1.8, 1.9, 2.2, and 0.9 mole per mole of the copper(II) salt for N2, Ar, O2, and Xe, respectively, indicating that the gases were not adsorbed on the surface but occluded within the solid.

Solvent Extraction of Metal Carboxylates

1985
Publisher Summary This chapter presents a study on solvent extraction of metal carboxylates. Carboxylic acids are conveniently utilized in the extraction of a number of metal ions. In the early 1950s, there were several procedures proposed, involving carboxylic acids for separation of metals such as copper and beryllium.

Preparation of dispersed metal nanoparticles in the aqueous solution of metal carboxylate and the tetra-n-butylammonium carboxylate

Journal of Crystal Growth, 2019
Abstract Nano-sized metal particles have been actively investigated. Although the synthesis methods of nano-sized metal particles have been made remarkable progress through many researches, in many cases, heat treatment is required. In order to promote industrial utilization, non-heating, simple and inexpensive synthesis methods are required.

Thermal behaviour of metal carboxylates: Metal formates

Spectrochimica Acta Part A: Molecular Spectroscopy, 1979
Abstract An analysis of emission spectra recorded on twelve metal formates under heating showed the existence of two crystal forms of anhydrous salts for some of them. The i.r. absorption spectra of these phases are reported. A comparison between final decomposition products and relative temperatures observed in air and under vacuum showed the ...

Carboxylations of alkali metal phenoxides with carbon dioxide

Organic & Biomolecular Chemistry, 2003
The reaction mechanism of the Kolbe-Schmitt reaction of phenol and 2-naphthol has been investigated. An alkali metal phenoxide-CO2 complex is not an intermediate that can be easily transformed into a carboxylic acid, such as salicylic acid (SA) and p-hydroxybenzoic acid (pHBA).
