しゅう酸銅(II) hemihydrate 化学特性,用途語,生産方法
化学的特性
Cupric oxalate is a bluish-white, odorless powder.
使用
As catalyst for organic reactions; as stabilizer for acetylated polyformaldehyde; in anticaries compositions; in seed treatments to repel birds and rodents.
製造方法
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.
一般的な説明
Odorless bluish-white solid. Denser than water and insoluble in water. Hence sinks in water. Used as a catalysts for organic reactions.
空気と水の反応
Insoluble in water.
反応プロフィール
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.
危険性
Toxic by ingestion; tissue irritant.
健康ハザード
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.
火災危険
Special Hazards of Combustion Products: Toxic carbon monoxide gas may form in fire.
職業ばく露
Used as a catalyst for organic reactions and in seed treatment as a repellent for birds and rodents.
輸送方法
UN2775, Copper based pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
不和合性
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.
