説明
Ferrous oxalate, or iron (II) oxalate, is a chemical compound consisting of one iron (II) ion (Fe
2+) and one oxalate ion (C
2O
42-). It has the chemical formula FeC
2O
4.
Iron(II) oxalate is more commonly encountered as the dihydrate, FeC
2O
4·2H
2O . Its crystal structure consists of chains of oxalatebridged iron atoms, capped by water molecules.
When heated, it dehydrates and decomposes into carbon dioxide, carbon monoxide, iron oxides and pyrophoric black iron.
化学的特性
Pale-yellow, crystalline powder; odorless. Soluble in acids; insoluble in water.
使用
Photographic developer, pigment in glass, plastics, paints.
一般的な説明
Odorless yellow solid. Insoluble in water and denser in water. Sinks in water.
空気と水の反応
Insoluble in water.
反応プロフィール
Inorganic reducing agents, such as Ferrous oxalate, react with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive.
危険性
Toxic. Evolves carbon monoxide on heating.
健康ハザード
Inhalation of dust may cause irritation of nose and throat. Ingestion causes burning pain in throat and stomach; mucous membranes turn white; can also cause vomiting, weak pulse, collapse, and death. Dust irritates eyes and may irritate skin on prolonged contact.
火災危険
Special Hazards of Combustion Products: Iron fume or iron oxide fume may form in fire.
