Оксалат меди (II)

Химические свойства

Cupric oxalate is a bluish-white, odorless powder.

Использование

As catalyst for organic reactions; as stabilizer for acetylated polyformaldehyde; in anticaries compositions; in seed treatments to repel birds and rodents.

Подготовка

Copper(II) oxalate can be prepared by reaction of sodium oxalate with copper(II) salt solutions. Copper(II) oxalate is used as a catalyst in organic reactions and as a stabilizer for acetylated polyformaldehyde.

Общее описание

Odorless bluish-white solid. Denser than water and insoluble in water. Hence sinks in water. Used as a catalysts for organic reactions.

Реакции воздуха и воды

Insoluble in water.

Профиль реактивности

Cupric oxalate dissolves in aqueous ammonia and reacts as an acid to neutralize other bases as well. Can serve as a reducing agent in reactions that generate carbon dioxide.

Опасность

Toxic by ingestion; tissue irritant.

Угроза здоровью

Inhalation causes irritation of nose and throat. Ingestion of very large amounts may produce symptoms of oxalate poisoning; watch for edema of the glottis and delayed constriction of esophagus. Contact with eyes causes irritation.

Пожароопасность

Special Hazards of Combustion Products: Toxic carbon monoxide gas may form in fire.

Возможный контакт

Used as a catalyst for organic reactions and in seed treatment as a repellent for birds and rodents.

UN2775, Copper based pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

Несовместимости

Explosive materials are formed on contact with acetylene gas, ammonia, caustic solutions; sodium hypobromite, nitromethane. Slight heating can cause a weak explosion. Cupric oxalate dissolves in aqueous ammonia and reacts as an acid to neutralize other bases as well. Can serve as a reducing agent in reactions that generate carbon dioxide. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
