ジヒドリド硫黄 化学特性,用途語,生産方法

用途

分析試験(金属沈殿剤)、金属の精製、各種工業薬品、農薬、医薬品の製造、蛍光体(夜光、蛍光染料)、エレクトロルミネッセンス(面照明)、フォトコンダクター(光電リレー露光計)製造、溶剤製造(DMSO、高級メルカプタン)、皮革処理(脱毛剤)

説明

Hydrogen Sulfide is a colorless, very poisonous, flammable gas with the characteristic foul odor of rotten eggs. It often results from the bacterial breakdown of organic matter in the absence of oxygen, such as in swamps and sewers where anaerobic digestion can take place. It also occurs in volcanic gases, “natural gas”, and some well waters. Hydrogen sulfide has numerous names, some of which are archaic.
Small amounts of hydrogen sulfide occur in crude oil, but natural gas can contain up to 90%. About 10% of the total global emission of H2S is due to human activity.

化学的特性

Hydrogen sulfide has a characteristic odor of rotten eggs.

化学的特性

Hydrogen sulfide has the characteristic odor of rotten eggs.

化学的特性

colourless gas with strong odour of rotten eggs (odour threshold ca 0.2 ppt)

物理的性質

H2S is soluble in carbon disulfide, methanol, acetone and alkanolamines. A solution of hydrogen sulfide in water is initially clear but over time turns cloudy. This is due to the slow reaction of hydrogen sulfide with the oxygen dissolved in water, yielding elemental sulfur, which precipitates out.

天然物の起源

Reported found in heated French beans, beef broth, vapors of canned beef, canned beef, beef extract, heated beef fat, raw beef, beer, bread, heated Brussels sprouts, cabbage, cooked celery, cheddar cheese, cooked and raw chicken, chives, heated coconut, codfish, ground and roast coffee, heated corn, heated egg, grapefruit juice, cooked herring, citrus juices, strawberry, cabbage, onion, potato, rutabaga, tomato, blue cheese, buttermilk, raw and boiled eggs, coffee, potato chips, rice, soybeans, okra, sweet corn, sake, squid, shrimps, cooked, fatty fish and other natural sources

来歴

Hydrogen sulfide is a colorless, flammable, toxic gas with the characteristic odor of rotten eggs.It is produced naturally from the anaerobic bacterial decomposition of organic wastes, occurs in volcanic gases and hot springs, is a product of animal digestion, and is generated in industrial processes. Hydrogen is a natural component of natural gas and petroleum; it is only a small fraction of oil (hundreds of ppm), but may form an appreciable component of natural gas. Natural gas typically contains up to 5% hydrogen sulfide. Natural gas is considered sour if the hydrogen sulfide content exceeds 5.7 mg of H2S per cubic meter of natural gas. The process for removing hydrogen sulfide from sour gas is referred to as sweetening the gas. Because hydrogen sulfide is associated with anaerobic respiration in sewers and swamps, it is referred to as sewer gas, swamp gas, or stink damp.

使用

Hydrogen sulfide has relatively few commercial uses. It is used to produce elementalsulfur, sulfuric acid, and heavy water for nuclear reactors.

使用

To produce elemental sulfur and sulfuric acid; in manufacture of heavy water and other chemicals; in metallurgy; as analytical reagent.

使用

Hydrogen sulfide is used as an analyticalreagent and in the manufacture of heavywater. It occurs in natural gas and sewer gas.It is formed by the reaction of a metal sulfidewith dilute mineral acid, and in petroleumrefining.

定義

ChEBI: A sulfur hydride consisting of s single sulfur atom bonded to two hydrogen atoms. A highly poisonous, flammable gas with a characteristic odour of rotten eggs, it is often produced by bacterial decomposition of organic matter in the absence of oxygen.

調製方法

Hydrogen sulfide is produced during anaerobic respiration (fermentation). Anaerobic respirationenables organisms, primarily bacteria and other microbes, to meet their energy needsusing sulfate, elemental sulfur, and sulfur compounds as electron acceptors instead of oxygen.

製造方法

By far the largest industrial route toH2S occurs in petroleum refineries. The “hydrodesulfurization” process liberates sulfur from petroleum by the action of hydrogen. The resulting H2S is converted to elemental sulfur by partial combustion via the Claus

Aroma threshold values

Detection: 10 ppb

空気と水の反応

Highly flammable; a flame can very easily flash back to the source of leak. Soluble in water to a maximum of 0.4% by mass at room temperature .

反応プロフィール

HYDROGEN SULFIDE reacts as an acid and as a reducing agent. Explodes on contact with oxygen difluoride, bromine pentafluoride, chlorine trifluoride, dichlorine oxide, silver fulminate. May ignite and explode when exposed to powdered copper in oxygen [Mertz, V. et al., Ber., 1880, 13, p. 722]. May react similarly with other powdered metals. Ignites on contact with metal oxides and peroxides (barium peroxide, chromium trioxide, copper oxide, lead dioxide, manganese dioxide, nickel oxide, silver oxide, silver dioxide, thallium trioxide, sodium peroxide, mercury oxide, calcium oxide) [Mellor, 1947, vol. 10, p. 129, 141]. Ignites with silver bromate, lead(II) hypochlorite, copper chromate, nitric acid, lead(IV) oxide and rust. May ignite if passed through rusty iron pipes [Mee, A. J., School Sci. Rev., 1940, 22(85), p. 95]. Reacts exothermically with bases. The heat of the reaction with soda lime, sodium hydroxide, potassium hydroxide, barium hydroxide may lead to ignition or explosion of the unreacted portion in the presence of air / oxygen [Mellor, 1947, vol. 10, p. 140].

危険性

Highly flammable, dangerous fire risk, explosive limits in air 4.3–46%. Toxic by inhalation, strong irritant to eyes and mucous membranes.

健康ハザード

Exposure to very high concentrations causes immediate death. Also death or permanent injury may occur after very short exposure to small quantities. It acts directly upon the nervous system resulting in paralysis of respiratory centers.

健康ハザード

The acute toxicity of hydrogen sulfide by inhalation is moderate. A 5-min exposure to 800 ppm has resulted in death. Inhalation of 1000 to 2000 ppm may cause coma after a single breath. Exposure to lower concentrations may cause headache, dizziness, and upset stomach. Low concentrations of H2S (20 to 150 ppm) can cause eye irritation, which may be delayed in onset. Although the odor of hydrogen sulfide is detectable at very low concentrations, it rapidly causes olfactory fatigue at higher levels, and therefore is not considered to have adequate warning properties. Hydrogen sulfide has not been shown to be carcinogenic or to have reproductive or developmental effects in humans

健康ハザード

Hydrogen sulfide is a highly toxic gas. Exposure to high concentrations can result inunconsciousness and respiratory paralysis.A 5-minute exposure to a concentration of1000 ppm can be lethal to humans. Prolonged exposure to concentrations between250 and 500 ppm can cause respiratory irri tation, congestion of the lung, and bronchialpneumonia. Toxic symptoms that have beennoted from occupational exposure to hydrogen sulfide in a heavy water plant areheadache, nausea, cough, nervousness, andinsomnia (ACGIH 1986). In addition, it isan irritant to the eyes. Conjunctivities mayresult from exposure to 20–30 ppm.

火災危険

Compound is heavier than air and may travel a considerable distance to source of ignition and flash back. HYDROGEN SULFIDE forms explosive mixtures with air over a wide range. Also reacts explosively with bromine pentafluoride, chlorine trifluoride, nitrogen triiodide, nitrogen trichloride, oxygen difluoride, and phenyl diazonium chloride. When heated to decomposition, HYDROGEN SULFIDE emits highly toxic fumes of oxides of sulfur. Incompatible with many materials including strong oxidizers, metals, strong nitric acid, bromine pentafluoride, chlorine trifluoride, nitrogen triiodide, nitrogen trichloride, oxygen difluoride and phenyl diazonium chloride. Avoid physical damage to containers; sources of ignition; storage near nitric acid, strong oxidizing materials, and corrosive liquids or gases.

火災危険

Hydrogen sulfide is flammable in air in the range of 4.3 to 45.5% (NFPA rating = 4). Combustion products (sulfur oxides) are also toxic by inhalation. In the event of a hydrogen sulfide fire, stop the flow of gas if possible without risk of harmful exposure and let the fire burn itself out.

燃焼性と爆発性

Hydrogen sulfide is flammable in air in the range of 4.3 to 45.5% (NFPA rating = 4). Combustion products (sulfur oxides) are also toxic by inhalation. In the event of a hydrogen sulfide fire, stop the flow of gas if possible without risk of harmful exposure and let the fire burn itself out.

农业用途

Hydrogen sulphide (H2S) is a colorless, poisonous, flammable gas with an odor of rotting eggs. It is found in cesspools and mines and is a by-product of decomposed substances containing sulphur. It is one of the gaseous end-products of the reduction of sulphate in highly degraded paddy fields. Hydrogen sulphide is also produced in the laboratory for use as an analytical reagent.

Chemical Synthesis

Hydrogen sulfide gas can be formed and released whenever waste containing sulfur is broken down by bacteria.

貯蔵

cylinders of hydrogen sulfide should be stored and used in a continuously ventilated gas cabinet or fume hood. Local fire codes should be reviewed for limitations on quantity and storage requirements.

純化方法

Wash it, then pass the gas through a train of tubes containing saturated Ba(OH)2 (2x), water (2x), and dilute HCl [Goates et al. J Am Chem Soc 73 707 1951]. It is available in gas cylinders. HIGHLY POISONOUS.

不和合性

Hydrogen sulfide is incompatible with strong oxidizers. It will attack many metals, forming sulfides. Liquid hydrogen sulfide will attack some forms of plastics, rubber, and coatings. H2S reacts violently with a variety of metal oxides, including the oxides of chromium, mercury, silver, lead, nickel, and iron.

廃棄物の処理

To respond to a release, use appropriate protective equipment and clothing. Positive pressure air-supplied respiratory protection is required. Close cylinder valve and ventilate area. Remove cylinder to a fume hood or remote area if it cannot be shut off. Disposal Excess hydrogen sulfide should be returned to the manufacturer, according to your institution's waste disposal guidelines. For more information on disposal procedures, see Chapter 7 of this volume.
