Overview
Copper(II) acetate, commonly referred to as cupric acetate, is an inorganic compound with significant industrial applications. It is primarily used as a catalyst in organic synthesis and as a pigment in various industries. The compound is known for its characteristic blue-green color and its ability to form complexes with organic molecules. In its industrial-grade form, copper(II) acetate typically has a purity of 98-99%. It is produced through the reaction of copper oxide or copper carbonate with acetic acid. The industrial grade is suitable for most commercial applications where ultra-high purity is not required.
Physical and Chemical Properties
Copper(II) acetate appears as blue-green crystalline powder that is hygroscopic in nature. It has a molecular weight of 181.63 g/mol and a density of approximately 1.882 g/cm³. The compound decomposes before reaching a true melting point, typically between 115-120°C. The substance is soluble in water and ethanol, and its solutions exhibit a characteristic blue color. Copper(II) acetate is an oxidizing agent and can form stable complexes with various organic ligands. These properties make it valuable in chemical synthesis and as a reagent in analytical chemistry.
Main Applications
In industrial settings, copper(II) acetate serves multiple functions. It is widely used as a catalyst in organic reactions, particularly in the production of pharmaceuticals and specialty chemicals. The compound also finds application as a fungicide in agriculture and wood preservation. Another significant use is as a pigment in paints, ceramics, and textiles, where it provides distinctive blue and green hues. In analytical chemistry, it serves as a reagent for various tests and as a source of copper ions in electroplating processes.
Safety and Storage
Copper(II) acetate requires careful handling due to its hazardous nature. It is harmful if swallowed and can cause skin and eye irritation. Appropriate personal protective equipment, including gloves and eye protection, should be worn when handling the substance. For storage, keep the compound in a cool, dry place away from incompatible materials such as strong acids and reducing agents. Containers should be tightly sealed to prevent moisture absorption and contamination. In case of spills, neutralize with sodium carbonate or bicarbonate before disposal.
B2B Procurement Guide
When procuring industrial-grade copper(II) acetate, buyers should specify their purity requirements, which typically range from 98-99% for most applications. It's essential to verify supplier certifications and request material safety data sheets (MSDS) before purchase. Bulk purchases generally offer better pricing, with common packaging options including 25kg bags or drums. Buyers should consider transportation and storage requirements, as the compound is hygroscopic. Lead times may vary depending on market demand and production schedules.
