Synthesis method for copper octoate

The embodiment of the invention provides a synthesis method for copper octoate, and relates to the field of organic synthesis. The synthesis method for copper octoate comprises the following steps that n-caprylic acid and copper oxide are mixed with a solvent with the mole ratio being 0.1-2:1, n-caprylic acid is dissolved into a solvent, a reaction is performed under the condition that the temperature is higher than the boiling point of the solvent, and a reactant is obtained; the reactant is subjected to solid-liquid separation. The copper octoate product is obtained by adopting the synthesismethod for copper octoate, and the purity of copper octoate in the copper octoate product reaches 99% or above. The synthesis method for copper octoate is simple, and the copper octoate product is high in purity.

Solventless synthesis of copper sulfide nanorods by thermolysis of a single source thiolate-derived precursor

Organic monolayer protected Cu2S nanorods, 4 nm in diameter and 12 nm long, were synthesized using a novel solventless synthetic approach. Thermolytic degradation of a copper thiolate precursor at temperatures ranging from 140 to 200 °C produces Cu2S nanorods. Higher temperatures promote isotropic growth of spherical nanocrystals. X-ray diffraction and high-resolution TEM reveal that the nanorods exhibit a hexagonal Cu2S crystal structure, which in the bulk is ferroelectric. The appropriate reaction conditions produce nanorods that are size and shape monodisperse and organize into smectic superlattices. The extent of superlattice ordering and the appearance of extended strands of nanorods provide evidence for strong dipole-dipole coupling between Cu2S nanorods. Copyright

Copper(II) carboxylates with 4-aminopyridine: Neutral mononuclear structures, isomerism of aceto compounds and a novel tetranuclear structure

Reactions of copper(II) carboxylates with 4-aminopyridine (4-apy) were investigated and their products structurally characterized by single crystal X-ray diffraction. Reaction of copper(II) acetate resulted in two isomers of a monomeric complex of composition Cu(ac)2(4-apy)2 with markedly different stabilities: the violet form, 1, unstable in air and the blue, stable form, 2. In both isomers the ligands are arranged around the copper atom in a trans geometry. The 4-apy ligands lie almost in the plane in 1, while they are twisted with respect to each other in 2. Variations were observed also in the coordination of the acetate groups to the copper ion. The energy difference between the two isomers was obtained on the basis of ab initio MO calculations. The result agrees well with the observed relative stabilities in the solid state. Monomeric complexes of the same stoichiometry were obtained also by the reaction of Cu(II) hexanoate and heptanoate with 4-apy. The violet Cu(hex)2(4-apy)2, 3, and Cu(hep)2(4-apy)2, 4, are isostructural and possess trans geometry of the ligands around the copper centre. Reaction of 4-apy with Cu(II) octanoate lead to formation of a novel, unprecedented basic centrosymmetric tetranuclear compound of composition Cu4(oct)6(OH)2(4-apy)2, 5. Complex 5 contains bidentate bridging and monoatomic bridging carboxylate groups, triply bridging hydroxyl groups and 4-aminopyridine as a terminal ligand. In all five compounds 4-apy is coordinated through the endocyclic nitrogen atom only.

Molar volume and apparent molar volume of copper(II) soap+methanol + benzene system at various temperatures

Studies on density of copper(II) soaps in mixture of benzene + methanol at various temperatures (40,45,50,55°C) have been made. The cmc values in higher volume percent of methanol are higher than those in higher volume percent of benzene. With regard to chain length of soaps cmc values follow the order C6>C8. Masson equation has been applied successfully to interpret apparent molar volume of copper soaps in benzene + methanol. The studies of temperature effect on various interactions suggest that interactions between soap-solvent molecules increase with the rise in temperature when non-polar hydrocarbon is predominant in the solvent mixture whereas soap-soap interactions increase with the rise in temperature when methanol is predominant at below and above cmc.

THE DIRECT ELECTROCHEMICAL SYNTHESIS OF SOME TRANSITION METAL CARBOXYLATES

The transition metal carboxylates M(O2CR)n (M=Cr, R=C2H5, C6H5, n=3; M=Mn, Fe, Ni, R=CH3, C2H5, C6H5, n-C7H15, n=2, not all combinations) have been prepared by oxidising suitable metal anodes electrochemically in solutions of RCOOH in acetonitrile.With Co and Cu, a wide range of carboxylic acids (R=C2H5, c-C3H5, c-C5H9, C6H5, n-C4H9, n-C7H15, 2-ethylhexanoic, oleic, linoleic) has been used succesfully to give M(O2CR)2.The advantages of the method are discussed.The preparation of Cu(O2CR)2 involves the prior formation of CuO2CR at the anode, followed by oxidation by the solvent.
