Synthesis and Improvement of Activity of Cobalt Organic Salts as Drier

Abstract

Organic salts of cobalt were synthesized in the presence of amine, ethanol, and ethyl methyl ketoxime and were used as drier for alkyd resin. Considering the drying time of alkyd resin containing synthesized compound showed that amines, as electron releasing groups (ERG), increased the oxidizing activity of drier and shortened drying time about an hour, whereas ethyl methyl ketoxime delayed the drying of resin 2 hours. Two methods of synthesis, including solution and precipitation processes of synthesis, were compared in terms of convenience, cost, and environmental aspects.

Co(iii) 2-ethylhexanoate, a hydrophobic and highly soluble Co(iii) precursor for thin coatings for water electrolysis

“…Other 2-ethylhexanoates have also been reported as mixtures of several metal ion clusters of different sizes, 17,26,32 and many metal soaps, including cobalt, exhibit various types of isomerism and form polynuclear complexes. 22,26,33,34…”

“…Co(III)eh is also likely to have practical implications for organic catalysis 33 and the synthesis of MOFs and cobaltbased nanoparticles in apolar solvents without requiring the addition of surfactants. 8,17,24,54 Due to its inertness to highly oxidizing conditions, Co(III)eh can be employed as a source of cobalt in the synthesis of composite materials that involve a strong oxidizing agent or a compound sensitive to reduction, such as graphene oxide, which Co(II)eh would instead instantly react with.…”

“…Other 2-ethylhexanoates have also been reported as mixtures of several metal ion clusters of different sizes, 17,26,32 and many metal soaps, including cobalt, exhibit various types of isomerism and form polynuclear complexes. 22,26,33,34 We performed thermogravimetric analysis (TGA) in an anoxic atmosphere to investigate the thermal stability of Co(II)eh and Co(III)eh compounds and to identify the temperature range of their thermal decomposition (Fig. 2d).…”

A density functional theory study on the mechanism of simultaneous trifluoromethylation and oximation of aryl-substituted ethylenes

“…Shen et al 33 investigated the activities of the electrophilic sites on the benzene ring of 4-substituted anilines and their acyl compounds through quantum chemical computations and chemical synthesis. Shiraz et al 34 used NICS (negative nucleus-independent chemical shift) calculations and energy barriers (Δ E ) to predict the most reactive site in azulene. It is common in chemistry to study the effects of substituents on reaction sites and reactivities by quantum chemistry computation.…”
