6046-93-1 Usage

Uses

Different sources of media describe the Uses of 6046-93-1 differently. You can refer to the following data:
1. Copper(II) acetate is used as a pigment for ceramics; in the manufacture of Paris green; in textile dyeing; as a fungicide; and as a catalyst.Copper(II) acetate monohydrate is used in DNA extraction in biochemical applications. It is also used as a catalyst or oxidizing agent in organic syntheses.Catalyst for activation of alcohols as greener alkylating reagents.Copper-Catalyzed Aerobic Oxidation of Amines to Imines under Neat Conditions with Low Catalyst Loading.
2. Cupric acetate monohydrate can be used in preparation of Fehling's reagent for sugars
3. Copper(II) acetate monohydrate is used in formation of Cu chelates of ?-dicarbonyl compounds as a means of purification and in the eglinton (modified glaser) coupling of terminal alkynes. It is also used as a catalyst for the michael reaction giving increased yields and absence of side-reactions. It Promotes ullmann-type C-O and C-N coupling reactions of arylboronic acids with phenols, amines and various other nitrogen derivatives. It is also used in biochemical applications such as DNA extraction.
4. Catalyst for activation of alcohols as greener alkylating reagentsCopper-Catalyzed Aerobic Oxidation of Amines to Imines under Neat Conditions with Low Catalyst Loading

Preparation

Different sources of media describe the Preparation of 6046-93-1 differently. You can refer to the following data:
1. Copper(II) acetate is prepared by treatment of copper(II) oxide, CuO, or copper(II) carbonate, CuCO3, with acetic acid, followed by crystallization: CuO + 2CH3COOH → (CH3COO)2Cu + H2O
2. Copper(II) acetate monohydrate can easily be produced by the reaction of acetic acid solutions with copper(II) carbonate or copper(II) hydroxide or by the reaction of copper(II) oxide with hot acetic acid. Large-scale commercial production uses copper metal in the presence of air and refluxing acetic acid. Copper(II) acetate monohydrate is used as a catalyst in the polymerization of organic materials and as a mordant in the dying of textiles. It is also used as a ceramic pigment and as a fungicide.

Toxicity

Copper(II) acetate is moderately toxic by ingestion and possibly other routes of administration. LD50 oral (rat): c. 600 mg/kg

Chemical Properties

Dark green small crystal with odour of acetic acid

General Description

Copper (II) acetate monohydrate is soluble in water and slightly soluble in methanol, diethylether and acetone. It can be synthesized by reacting acetic acid with copper (II) carbonate or copper(II) hydroxide or copper (II) oxide. Large scale commercial production is undertaken by placing copper metal in the presence of air and refluxing acetic acid. As a transition metal acetate, it can be used to form oxide nanoparticles by sonochemical methods.

Check Digit Verification of cas no

The CAS Registry Mumber 6046-93-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,4 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6046-93:
(6*6)+(5*0)+(4*4)+(3*6)+(2*9)+(1*3)=91
91 % 10 = 1
So 6046-93-1 is a valid CAS Registry Number.

Metal isotope and density functional study of the tetracarboxylatodicopper(II) core vibrations

Drozdzewski, Piotr,Brozyna, Anna

, p. 703 - 710 (2005)

Vibrational spectra of tetrakis(acetato)diaquadicopper(II) complex have been deeply examined in order to provide a detailed description of dynamics of [Cu2O8C4] core being a typical structural unit of most copper(II) carboxylates. Low frequency bands related to significant motions of metal atoms were detected by metal isotope substitution. Observed spectra and isotope shifts were reproduced in DFT calculations. For clear presentation of computed normal vibrations, a D4h symmetry approximation was successfully applied. Basing on observed isotope shifts and calculation results, all skeletal vibrations have been analyzed including normal mode with the largest Cu...Cu stretching amplitude assigned to Raman band at 178 cm-1.

Effect of a tridentate ligand on the structure, electronic structure, and reactivity of the copper(I) nitrite complex: Role of the conserved three-histidine ligand environment of the type-2 copper site in copper-containing nitrite reductases

It is postulated that the copper(I) nitrite complex is a key reaction intermediate of copper containing nitrite reductases (Cu-NiRs), which catalyze the reduction of nitrite to nitric oxide (NO) gas in bacterial denitrification. To investigate the structure-function relationship of Cu-NiR, we prepared five new copper(I) nitrite complexes with sterically hindered tris(4-imidazolyl) carbinols [Et-TIC = tris(1-methyl-2-ethyl-4-imidazolyl)carbinol and iPr-TIC = tris(1-methyl-2-isopropyl-4-imidazolyl)carbinol] ortris(1-pyrazolyl)methanes [Me-TPM = tris(3,5-dimethyl-1-pyrazolyl)methane; Et-TPM = tris(3,5-diethyl-1- pyrazolyl)methane; and iPr-TPM = tris(3,5-diisopropyl-1-pyrazolyl)methane]. The X-ray crystal structures of all of these copper(I) nitrite complexes were mononuclear η1-N-bound nitrite complexes with a distorted tetrahedral geometry. The electronic structures of the complexes were investigated by absorption, magnetic circular dichroism (MCD), NMR, and vibrational spectroscopy. All of these complexes are good functional models of Cu-NiR that form NO and copper(II) acetate complexes well from reactions with acetic acid under anaerobic conditions. A comparison of the reactivity of these complexes, including previously reported (iPr-TACN)Cu(NO2) [iPr-TACN = 1,4,7-triisopropyl-1,4,7-triazacyclononane], clearly shows the drastic effects of the tridentate ligand on Cu-NiR activity. The copper(I) nitrite complex with the Et-TIC ligand, which is similar to the highly conserved three-histidine ((His)3) ligand environment in the catalytic site of Cu-NiR, had the highest Cu-NiR activity. This result suggests that the (His)3 ligand environment is essential for acceleration of the Cu-NiR reaction. The highest Cu-NiR activity for the Et-TIC complex can be explained by the structural and spectroscopic characterizations and the molecular orbital calculations presented in this paper. Based on these results, the functional role of the (His) 3 ligand environment in Cu-NiR is discussed.

Mg storage properties of hollow copper selenide nanocubes

Cao, Shun-An,Chen, Dong,Li, Ting,Luo, Wei,Shen, Jingwei,Xu, Fei

, p. 13253 - 13261 (2020/10/13)

Rechargeable Mg batteries are thought to be suitable for scalable energy-storage applications because of their high safety and low cost. However, the bivalent Mg2+cations suffer from sluggish solid-state diffusion kinetics. Herein, a hollow morphological approach is introduced to design copper selenide cathodes for rechargeable Mg batteries. Hollow Cu2?xSe nanocubes are fabricatedviaa solution reaction and their Mg-storage properties are investigated in comparison to simple nanoparticles. The hollow structures accommodate the volume change during magnesiation/demagnesiation and maintain material integrity, and thus a remarkable cycling stability of over 200 cycles is achieved. A kinetic study demonstrates that a hollow structure favors solid-phase Mg2+diffusion, and therefore the hollow Cu2?xSe nanocubes exhibit a high capacity of 250 mA h g?1at 100 mA g?1as well as a superior rate capability. Mechanism investigation indicates that Cu2?xSe experiences a structure conversion during which a phase transformation occurs. This work develops a facile method for the preparation of hollow copper selenides and highlights the advantages of hollow structures in the design of high-performance Mg-storage materials.
