COPPER FORMATE Usage And Synthesis

Chemical Properties

three forms of anhydrous formate exist: powder(s) blue, turquoise or royal blue crystal(s) [MER06].
Copper(II) formate is a royal blue material that obtains by crystallization from 75-85°C solutions. Crystallization from solutions at temperatures of 50-60°C results in the formation of a metastable dihydrate. A tetrahydrate can be produced by crystallization at lower temperatures.

Uses

Copper formate is used for the control of bacteria and mildew in cellulosic materials.

Preparation

Copper(II) formate is produced by dissolution of copper(II) oxide in hot formic acid or by the reaction of copper(II) carbonate or hydroxide with formic acid. It can also be produced by aeration of hot formic acid over copper metal.

General Description

Blue crystalline powder. Sinks and mixes with water.

Air & Water Reactions

Water soluble.

Reactivity Profile

Salts, basic, such as COPPER FORMATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.

Health Hazard

INHALATION: May cause nasal congestion. EYES: May cause conjunctivitis. SKIN: Irritation. INGESTION: Irritation.
