• 説明

  Metam sodium is a crystalline material with an unpleasant odor of sulfur compounds. It reacts in water to generate methyl isothiocyanate, which is the active material. It is applied as a freshly diluted solution in water.

• 化学的特性

  White, crystalline solid. Readily soluble in water; moderately soluble in alcohol; stable in concentrated aqueous solution but decomposes in dilute aqueous solution; unstable in moist soil.

• 使用

  Metam Sodium is useful as an environmental-friendly and sustainable electrocatalyst for oxygen reduction reactions.

• 一般的な説明

  A yellow to light yellow-green aqueous solution with an odor of amine and sulfur that varies in intensity. Boiling point 230°F. Metham sodium has a specific gravity of 1.162. Metham sodium will decompose upon dilution to carbon disulfide, monomethylamine, methylisothiocyanate, and hydrogen sulfide. The decomposition products are flammable and toxic. The acute symptoms of exposure to metam sodium are excessive salivation, sweating, fatigue, weakness, nausea, headache, dizziness, eye and respiratory tract irritation, and skin irritation in the form of rashes. The spillage of a rail car tanker of metal sodium into the Sacramento River caused a major fish kill (over a million trout) along several miles of that river.

• 空気と水の反応

  Slow reaction upon dilution produces toxic gases hydrogen sulfide and methylisothiocyanate. This reaction is accelerated by the addition of acid.

• 反応プロフィール

  METAM SODIUM is a dithiocarbamate. Flammable gases are generated by the combination of thiocarbamates and dithiocarbamates with aldehydes, nitrides, and hydrides. Thiocarbamates and dithiocarbamates are incompatible with acids, peroxides, and acid halides.

• 危険性

  Irritant to tissue, toxic to plants and vege- tation.

• 健康ハザード

  TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

• 火災危険

  Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

• 不和合性

  Slow reaction upon dilution in water releasing toxic gases of hydrogen sulfide and methyl isothiocyanate. This reaction is accelerated by the addition of acid. May liberate toxic gas when in contact with acids. Combustible; vapors when heated or dust from dry material may form explosive mixture in air. Dithiocarbamate esters are combustible. They react violently with powerful oxidizers such as calcium hypochlorite. Poisonous gases are generated by the thermal decomposition of Dithiocarbamate compounds, including carbon disulfide, oxides of sulfur, oxides of nitrogen, hydrogen sulfide, ammonia, and methylamine. Thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids. Flammable gases are generated by the combination of dithiocarbamate with aldehydes, nitrides, and hydrides. Dithiocarbamate are incompatible with acids, peroxides, and acid halides. Corrosive to iron, copper brass and zinc metals, especially in the presence of moisture. Heat alkalies (lime), moisture can cause decomposition. Degradation produces ethylene thiourea.

• 廃棄物の処理

  Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform to EPA regulations governing storage, transportation, treatment, and waste disposal. A potential candidate for liquid injection incineration at a temperature range of 650 to 1600C and a residence time 0.1 to 2 seconds. Also, a potential candidate for rotary kiln incineration at a temperature range of 820 to 1600C and residence times of seconds for liquids and gases, and hours for solids.
