塩化アンモニウム 化学特性,用途語,生産方法

• 外観

  白色の結晶性の粉末又は結晶塊

• 性質

  化学式 NH4Cl 。塩化アンモニウムは，無色の結晶または白色粒状の固体。冷たい辛みがある。いくぶん潮解性。比重 1.54 。 337.8℃で昇華し，NH3 と HCl に解離する。水に易溶。水溶液はほぼ中性であるが，煮沸するとアンモニアが抜けて，塩化水素が残るため酸性となる。メチルアルコール，エチルアルコールに可溶，アセトン，エーテル，酢酸エチルに難溶。亜鉛鉄板製造の融剤，乾電池，マンガン乾電池の製造，窒素肥料 (→塩安 ) などのほか，去痰剤にも用いられる。

• 定義

  本品は、アンモニアの塩化物であり、次の化学式で表される。

• 溶解性

  水に溶けやすく、エタノールに溶けにくい。

• 解説

  肥料としての正式名称は塩化アンモニアで，塩安と略称。化学式NH4Cl。天然には，火山噴気孔付近に昇華鉱物鹵砂（ろしや）(〈どうしゃ〉とも読む)として産する。無色で，結晶は立方晶系。高温安定のα型，低温安定のβ型とγ型の3種の変態があり，転移点は184℃と－30.3℃である。α型は塩化ナトリウムNaCl型構造，β型とγ型は塩化セシウムCsCl型構造。337.8℃で昇華し，アンモニアと塩化水素に解離するが，温度を下げると再結合し塩化アンモニウムの結晶を生ずるので高純度精製に利用される。

• 解説

  代表的なアンモニウム塩の一つ。工業的には塩安とよばれる。天然には火山噴出物や温泉の中にみいだされるが、工業的には、アンモニアソーダ法（塩安ソーダ法）で炭酸ナトリウム（ソーダ灰）を製造する際の副産物として生産される。

  実験室ではアンモニアと塩酸の中和、硫酸アンモニウムと塩化ナトリウムの複分解などで得られる。無色の結晶性固体で、α(アルファ)、β(ベータ)、γ(ガンマ)の3種の変態があり、転移温度は184.3℃、および零下30.3℃である。高温では安定なα形は塩化ナトリウム型構造であるが、βおよびγ形は塩化セシウム型構造である。熱すると昇華して気体となり、塩化水素とアンモニアとに分解する。苦味を帯びた辛味があり、幾分吸湿性で、水によく溶ける。水溶液はほとんど中性であるが、加熱するとアンモニアが分離するので酸性となる。窒素肥料として大量に使用されるが、工業的にははんだづけ、めっきの際の表面清浄剤（フラックス）、乾電池の合剤、電解液の調製などに用いられる。分析試薬、医薬（去痰(きょたん)薬、利尿薬）としての用途もある。

• 化学的特性

  Ammonium chloride,Nl4CI, also known as ammoniae, salmiai,and ammonium nituriate,is a white crystalline solid. It is soluble in water, aqueous solutionsof ammonia, and is slightly soluble in methyl alcohol. Ammonium chloride is found in natureas a sublimation productof volcanic activity, or is produced by neutralizing HCI(either in liquid or gaseousphase) with NH3 gas or liquid NH40H then evaporating the excess H20. The salt decomposes at350°C and sublimes under controlled conditions at 520 °C. Ammoniumchlorideis used as an electrolyte in dry cell batteries,as a fluxfor soldering, tinningandgalvanizing, andas a processing ingredientin textile printing and hide tanning. Use as a source of nitrogen for fertilizersis limited because of the possible build up of damaging chloride residuals in the soil.

• 物理的性質

• 天然物の起源

  Ammonium chloride occurs in nature in crevices near volcanoes. Also, it is found in smoke when burning dry camel or donkey dung as fuel. Important applications of this compound include the manufacture of dry cells for batteries; as a metal cleaner in soldering; as a flux in tin coating and galvanizing; in fertilizers; in pharmaceutical applications as a diuretic, or diaphoretic expectorant; and as an analytical standard in ammonia analysis. Also, it is used in freezing mixtures; washing powders; lustering cotton; in safety explosives and in dyeing and tanning.

• 主な応用

  Ammonium chloride is also known as sal ammoniac. white crystals made by ammonia salts acting upon hydrochloric acid followed by crystallization. It was used as a halide in many processes, including the salted paper, albumen paper, albumen opaltype, and gelatin emulsion processes. ammonium chloride is also used as a thickener and as an additive in non-alcoholic toners. According to cosmetic formulators, the ammonium component provides the tingling or stinging sensation that some people associate with toners or aftershaves, and which, in regular toners, is usually provided by the alcohol content. Ammonium chloride’s use is the result of preference in formulation feel.

• 製造方法

  Ammonium chloride is prepared commercially by reacting ammonia with hydrochloric acid. It may be prepared by fractional crystallization from a solution containing ammonium sulphate and sodium chloride or ammonium carbonate and calcium chloride. Because of it sease of preparation it can be manufacture dindustrially along side any plant that uses or produces ammonia. Ammonium chloride is used in dry cells, metal finishing, and in the preparation of cotton for dyeing and printing.

• 定義

  ChEBI: Ammonium chloride is an inorganic chloride having ammonium as the counterion. It has a role as a ferroptosis inhibitor. It is an inorganic chloride and an ammonium salt.

• 一般的な説明

  Ammonium chloride is a white crystalline solid. Ammonium chloride is soluble in water(37%). The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. Ammonium chloride is used to make other ammonium compounds, as a soldering flux, as a fertilizer, and for many other uses.

• 空気と水の反応

  Soluble in water. Slowly releases hydrogen chloride [USCG, 1999].

• 反応プロフィール

  Acidic salts, such as Ammonium chloride , are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

• 危険性

  Eye and upper respiratory tract irritant.

• 健康ハザード

  Inhalation of fumes irritates respiratory passages. Ingestion irritates mouth and stomach. Fumes are irritating to eyes. Contact with skin may cause irritation.

• 安全性

  Ammonium chloride is used in oral pharmaceutical formulations. The pure form of ammonium chloride is toxic by SC, IV, and IM routes, and moderately toxic by other routes. Potential symptoms of overexposure to fumes are irritation of eyes, skin, respiratory system: cough, dyspnea, and pulmonary sensitization. Ammonium salts are an irritant to the gastric mucosa and may induce nausea and vomiting.
