亜硫酸ジナトリウム 化学特性,用途語,生産方法

外観

無~白色の結晶又は白色の粉末

定義

本品は、亜硫酸の二ナトリウム塩であり、次の化学式で表される。

溶解性

水に溶けやすく、エタノールにやや溶けにくい。

解説

亜硫酸ソーダともよばれる。硫化鉱や硫黄(いおう)の燃焼によって生じた二酸化硫黄を、炭酸ナトリウムまたは水酸化ナトリウム水溶液に吸収させて製造する。最近では硫黄分の多い燃料の燃焼ガス中に含まれる二酸化硫黄を、公害防止対策として、アルカリ溶液に吸収させることが行われており、またフェノール類製造時にも副生する。37℃以下で濃縮すると七水和物(無色、単斜晶系)が結晶し、これを加熱、脱水すると無水和物(無色、六方晶系)が得られる。七水和物は不安定で、33.4℃以上で無水和物に転移する。いずれも水によく溶け、アルカリ性を呈するが、アルコールには溶けない。強い還元性を示す。合成繊維の染料の製造、チオ硫酸ナトリウムの製造原料、皮革のタンニン溶解剤、染色助剤、漂白剤、写真現像定着助剤、医薬などに用いられる。また、公害防止の回収品や副生品はパルプ用蒸解剤として大量に使用される。[鳥居泰男][補完資料] | 亜硫酸ナトリウム(データノート)

化学的特性

Sodium sulfite,Na2S03, is a white,water-soluble, crystalline solid with a sulfurous, salty taste. It decomposes when heated. Sodium sulfite is used as a source of sulfite,as a chemical intermediate and food preservative, in medicine and paper manufacturing, in photographic developing, and as a bleaching agent in the textile industry. Most boiler operators use sodium sulfite for chemicals cavenging of oxygen in the feedwater. Because it decomposes into acidic gases at the high temperatures that accompany high pressures, sodium sulfite should not be used for this purpose at pressures above 122atm (12.4MPa,or 1.8 ksi).

化学的特性

Sodium sulfite is a white crystalline solid

化学的特性

Sodium sulfite occurs as an odorless white powder or hexagonal prisms. Note that the commercially available sodium sulfite is often presented as a white to tan- or pink-colored powder that would not conform to the pharmacopeial specification.

使用

sodium sulfite has anti-septic, preservative, and anti-oxidant properties. Sodium sulfite is also a topical anti-fungal.

使用

These white crystals were prepared by passing sulfurous gas over moist sodium carbonate. Sodium sulfite is soluble in water but less so in alcohol. It was used as a preservative for alkaline developers and as a hypo clearing agent in photographic printing.

使用

Paper industry (semichemical pulp), reduc- ing agent (dyes), water treatment, photographic developer, food preservative and antioxidant, tex- tile bleaching (antichlor).

定義

ChEBI: An inorganic sodium salt having sulfite as the counterion.

調製方法

Sodium bisulfite is prepared by reacting sulfur dioxide gas with sodium hydroxide solution. The solid material is obtained by evaporation of water. Further neutralization with sodium hydroxide while keeping the temperature above 33.6°C leads to crystallization of the anhydrous sodium sulfite (below this temperature the heptahydrate form is obtained).

定義

sodium sulphite: A white solid,Na2SO3, existing in an anhydrousform (r.d. 2.63) and as a heptahydrate(r.d. 1.59). Sodium sulphite is solublein water and because it is readily oxidizedit is widely used as a convenientreducing agent. It is preparedby reacting sulphur dioxide with eithersodium carbonate or sodium hydroxide.Dilute mineral acids reversethis process and release sulphur dioxide.Sodium sulphite is used as ableaching agent in textiles and inpaper manufacture. Its use as an antioxidantin some canned foodstuffsgives rise to a slightly sulphuroussmell immediately on opening, butits use is prohibited in meats or foodsthat contain vitamin B1. Sodium sulphitesolutions are occasionally usedas biological preservatives.

一般的な説明

White odorless powder. Density 2.633 g / cm3. Moderately toxic. Sinks in water and dissolves slowly. Also transported as a heptahydrate Na2SO3.7H2O.

空気と水の反応

Soluble in water. Reacts with hot water, steam or acids to produce corrosive material.

反応プロフィール

Sodium sulfite is a reducing agent, particularly under basic conditions. Reacts with oxidizing agents such as peroxides, epoxides, oxoacids. Emits toxic fumes of sodium oxide and oxides of sulfur if heated to decomposition [Lewis, 3rd ed., 1993, p. 1174].

危険性

Use prohibited in meats and other sources of Vitamin B 1

健康ハザード

When ingested, solutions cause gastric irritation by the liberation of sulfurous acid. Because of rapid oxidation to sulfate, sulfites are well tolerated until large doses are reached; then violent colic and diarrhea, circulatory disturbances, central nervous depression, and death can occur.

火災危険

Literature sources indicate that Sodium sulfite is noncombustible.

応用例(製薬)

Sodium sulfite is used as an antioxidant in applications similar to those for sodium metabisulfite. It is also an effective antimicrobial preservative, particularly against fungi at low pH (0.1% w/v of sodium sulfite is used). Sodium sulfite is used in cosmetics, food products, and pharmaceutical applications such as parenteral formulations, inhalations, oral formulations, and topical preparations.

接触アレルゲン

Sodium sulfite is mainly used in photographic developers, for fixing prints, bleaching textile fibers, as a reducer in manufacturing dyes, as a remover of Cl in bleached textiles and paper, and as a preservative in the food industry for meat, egg yolks, and so on.

安全性プロファイル

Poison by intravenous and subcutaneous routes. Moderately toxic by ingestion and intraperitoneal routes. Human mutation data reported. When heated to decomposition it emits very toxic fumes of Na2O and SOx. A reducing agent. See also SULFITES.

安全性

Sodium sulfite is widely used in food and pharmaceutical applications as an antioxidant. It is generally regarded as relatively nontoxic and nonirritant when used as an excipient. However, contact dermatitis and hypersensitivity reactions have been reported. The acceptable daily intake for sodium sulfite has been set at up to 350 mg/kg body-weight daily.
LD50 (mouse, IP): 0.950 g/kg
LD50 (mouse, IV): 0.130 g/kg
LD50 (mouse, oral): 0.820 g/kg
LD50 (rabbit, IV): 0.065 g/kg
LD50 (rabbit, oral): 1.181 g/kg
LD50 (rat, IV): 0.115 g/kg

職業ばく露

Sodium sulfite is used as a reducing agent; in boiler water treatment; food applications; in photographic developers and fixers; in bleaching of wool, paper, textiles, straw and silk; manufacture of dyes; dechlorination; preservation of meat, fruit and egg products; silvering of glass.

環境運命予測

Because sodium sulfite is a solid powder that is generally sold as a ‘food grade’ substance, there is very little information available on the environmental fate of sodium sulfite. It has a molecular weight of 126.04 g mol-1. At 20°C, the solubility in water is 250 000 mg l-1, and as it is an inorganic salt the vapor is negligible (USEPA, 2011). The log octanol/water partition coefficient is estimated to be 7.78.
If released into water or soil, sodium sulfite would most likely be oxidized to sulfate, which would then be available for use by bacteria or plants as a nutrient.
The US Environmental Protection Agency (EPA) EPI Suite computer program (USEPA, 2011) estimates both a bioconcentration factor and a bioaccumulation factor of 0.89. These factors are less than one, meaning that bioconcentration and/or bioaccumulation of sodium sulfite would be virtually negligible and therefore would not cause any adverse effects to fish and wildlife.

貯蔵

Sodium sulfite should be stored in a well-closed container in a cool, dry, place. In solution, sodium sulfite is slowly oxidized to sulfate by dissolved oxygen; strong acids lead to formation of sulfurous acid/ sulfur dioxide. On heating, sodium sulfite decomposes liberating sulfur oxides.

輸送方法

UN3260 Corrosive solid, acidic, inorganic, n.o.s., Hazard class: 8; Labels: 8-Corrosive material.

純化方法

Crystallise the sulfite from warm water (0.5mL/g) by cooling to 0o. Also purify it by repeated crystallisation from deoxygenated water inside a glove-box, and finally drying it under vacuum. [Rhee & Dasgupta J Phys Chem 89 1799 1985.]

Toxicity evaluation

The exact mechanism of toxicity has not been elucidated, although there is a lot of information on how sulfur-based compounds are detoxified by the liver. Sodium sulfite is a mild reducing agent that would most likely cause burning or irritation at the site of exposure or application by altering oxidation–reduction potential and pH.
Sulfites are used widely as antioxidants to keep foods from prematurely spoiling and to keep them looking ‘fresh’ by preventing oxidation and subsequent ‘browning.’ Many people, however, are ‘sulfite sensitive.’ After ingestion of food or beverages containing sulfite, these people may have allergictype reactions such as asthmatic wheezing, hypotension, tingling sensations, and flushing of the skin. The mechanism is unclear but probably has to do with an individual-specific chemical stimulation of the immune system, which in turn releases small amounts of vasoactive substances.

不和合性

Sodium sulfite is incompatible with acids, oxidizing agents, many proteins, and vitamin B1.

不和合性

A strong reducing agent. 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. Reacts with strong acids producing toxic sulfur dioxide.

規制状況(Regulatory Status)
