• 定義

  本品は、次の化学式で表される無機塩である。

• 用途

  亜硫酸パルプ蒸解剤，還元剤，医薬などに使用される。

• 化粧品の成分用途

• 化学的特性

  Ammonium sulfite is a colorless to yellow crystalline (sand-like or sugar-like) solid, normally sold or used in a 40% solution. It is used both as a reducing agent and in photography. This compound is a salt that can form from the reaction of ammonia and sulfur dioxide or hydrogen sulfide. This product is frequently found in the overhead of crude distillation units and can be quite corrosive to steel equipment. Chemical corrosion inhibitors are often used to control corrosion from ammonium sulfite and other ammonium salts.

• 物理的性質

  Colorless monoclinic crystals. Soluble in water, its aqueous solution is alkaline. Slightly soluble in alcohol. Insoluble in acetone and carbon disulfide. It is easily oxidized to ammonium sulfate in air. It can be decomposed into ammonia and sulfur dioxide when heated.

• 使用

  Ammonium Sulfite is an additive used in the production of caramel.

• 製造方法

  In the ATS process, sulfur dioxide is absorbed from incinerated Claus tail gas in aqueous ammonia to produce ammonium sulfite and ammonium bisulfite in solution.

• 一般的な説明

  AMMONIUM SULFITE is a colorless crystalline solid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. AMMONIUM SULFITE is used in the manufacture of other chemicals, in medicine, and photography.

• 空気と水の反応

  Soluble in water.

• 反応プロフィール

  AMMONIUM SULFITE is a reducing agent. Emits toxic sulfur dioxide and oxides of nitrogen when heated to decomposition [USCG, 1999].

• 健康ハザード

  Inhalation of dust causes irritation of nose and throat. Ingestion causes irritation of mouth and stomach. Dust irritates eyes.

• 火災危険

  Special Hazards of Combustion Products: Toxic sulfur dioxide and oxides of nitrogen may form in fires.

• 化学性质

  一水和物は色の単斜晶系の結晶で，比重1.41，加熱により分解し，吸湿性で水によく溶解する。空気中で徐々に酸化して硫酸アンモニウムになる。

• 職業ばく露

  Ammonium sulfite is used in medicines, metal lubricants; explosives, photography, hair wave solutions; and to make other chemicals. It is also used as a preservative, and for treating agricultural grain.

• 合成方法

  接触式硫酸プラントの排ガスなどをアンモニアで回収する。

• 輸送方法

  UN2693 Bisulfites, inorganic, aqueous solutions, n.o.s., Hazard class: 8; Labels: 8-Corrosive material. UN3077 Environmentally hazardous substances, solid, n.o. s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

• 不和合性

  A strong reducing agent. Reacts violently with strong 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.

• 廃棄物の処理

  Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal,state, and local environmental regulations must be observed. May be buried in a chemical waste landfill in accordance with federal, state, and local statutes; or, if oxidized and neutralized, it may be sent to a municipal sewage treatment plant for biological treatment Incineration.
