Copper(ii) acetate is odorless and efflorescent. It is soluble in alcohol and slightly soluble in ether and glycerol. Copper acetate has many applications, including as a fungicide, insecticide as well as applications in electrolysis and electroplating.

Copper(ii) acetate, also referred to as cupric acetate, is the chemical compound with the formula cu(oac)2 where oac, is acetate (ch3co, 2). The hydrated derivative, which contains one molecule of water for each cu atom, is available commercially.

Anhydrous cu(oac)2 is a dark green crystalline solid, whereas cu2(oac)4(h2o)2 is more bluish-green. Since ancient times, copper acetates of some form have been used as fungicides and green pigments. Today, copper acetates are used as reagents for the synthesis of various inorganic and organic compounds.Copper acetate, like all copper compounds, emits a blue-green glow in a flame

Usage 1: It is used as a fast-drying agent for paints, a pharmaceutical and chemical agent, a pesticide adjuvant, a raw material for porcelain glaze pigments, an analytical reagent, etc. Copper acetate can also be used as an agricultural fungicide, analytical reagent, astringent, mordant and coating, etc. When copper acetate is used as a fungicide, it is highly effective against bacterial angular spot disease of cucumbers, red spot disease of eggplants, apple tree rot and downy mildew of grapes. It is a highly efficient, low-toxicity and broad-spectrum fungicide. 3. It can be used as an analytical reagent and a chromatographic analytical reagent. 4.Chemicalbook is also used as an organic synthesis catalyst, for ceramic coloring, and for pesticides, etc. 5. Prepare the intermediate of Paris Green. 6. Insecticides, dyeing and printing fixatives. 7. Copper acetate can act as an oxidant for carbanions, free radicals and hydrocarbon compounds, enabling oxidative coupling reactions of electronegative substrates and solvent cleavage reactions of Si-C, Bi-C, Pb-C and Sb-C bonds. It can also be used for the cyclopropenylation reaction of alkenes and diazo esters. Copper acetate can also participate in the reaction as a Lewis acid.

Storage
NPS(SPS) is not combustible but assists combustion materials due to release of oxygen.Provided it is stored under appropriate condition.It must be stored dry in closed containers and protected from direct sunlight,heat and humidity.Impurities such as dirt,rust or traces of metal and reductants may cause catalytic decomposition.The product as supplied or in solution needs to be handled with appropriate care.The eye,skin and clothes must be protected when working with NPS(SPS) as damp powder or aqueous solution has a bleaching and slightly corroding effect.
Application
Polymerization : Initiator for the emulsion or solution Polymerization of acrylic monomers,vinyl acetate,vinyl chloride etc.and for the emulsion co-polymerization of styrene,acrylonitrile,butadiene etc.
Metal treatment : Treatment of metal surfaces(e.g. in the manufacture of semiconductors;
cleaning and etching of printed circuits),activation of copper and aluminium surfaces.
Cosmetics : Essential component of bleaching formulations.
Paper : modification of starch,repulping of wet - strength paper.
Textile : Desizing agent and bleach activator - particularly for cold bleaching.(i.e.bleaching of Jeans).

Artha Mineral Resources

Supplier From Mumbai, Maharashtra, India

Supplier Of Bauxite & Aluminium Ore

Calcined Bauxite:

Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature (from 850 oC to 1600 oC). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content of 82 % to 86 %. The heating is carried out in rotary kilns. Calcination is done at different temperatures ranging from 850 oC to 1600 oC depending upon the customer’s application.

We export Calcined Bauxite for various applications such as refractory bricks, abrasives, steel polishing, etc. We provide consistency in quality and availability of Calcined Bauxite at extremely competitive prices.

Applications of Calcined Bauxite:

Refractory Grade Calcined Bauxite (CB - I and CB - II Grade) : To make refractory grade, Bauxite is thermally treated at 1600 oC to produce Calcined Bauxite where the Alumina content is mostly above 82%.

Brown Fused Alumina, Proppants and Road Surfacing : To make the above grades, Bauxite is thermally treated at 1000 oC - 1200 oC to produce Calcined Bauxite where the Alumina content is anywhere between 80-88% depending on the requirement.
