White to yellow powder
使用
Reverse dyeing with aniline black; manufacture of safety matches and cartridges.
一般的な説明
A white to yellow crystalline solid. Slightly soluble in water and denser than water. Primary hazard is threat to the environment. Immediate steps should be taken to limit spread to the environment. Used to make explosives, safety matches, and in dyeing.
空気と水の反応
Slightly soluble in water.
反応プロフィール
Nitric acid violently oxidized a thiocyanate solution [Bretherick 1979. p. 121]. Caution should be exercised in treating a thiocyanate with an oxidizing agent such as a peroxide or chlorate as such mixtures have been known to explode. May be thermally unstable. Special Hazards of Combustion Products: Irritating sulfur dioxide gas may form in fire [USCG, 1999].
健康ハザード
Early symptoms of lead intoxication via inhalation or ingestion are most commonly gastrointestinal disorders, colic, constipation, etc.; weakness, which may go on to paralysis, chiefly of the extensor muscles of the wrists and less often of the ankles, is noticeable in the most serious cases. Ingestion of a laarge amount causes local irritation of the alimentary tract; pain, leg cramps, muscle weakness, paresthesias, depression, coma, and death may follow in 1 or 2 days. Contact causes irritation of eyes and mild irritation of skin.

不和合性
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,
strong acids, oxoacids, and epoxides. Contact with acids or
acid fumes caused decomposition with fumes of cyanide.
Will decompose in hot water.
