Special Hazards of Combustion Products: Irritating oxides of sulfur and nitrogen may form in fire. (USCG, 1999)
Special Hazards of Combustion Products: Irritating oxides of sulfur and nitrogen may form in fire. (USCG, 1999)
Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
Inhalation of dust causes irritation of nose and throat. Ingestion of large doses causes vomiting, extreme cerebral excitement, convulsions, and death in 10-48 hrs.; chronic poisoning can cause flu-like symptoms, skin rashes, weakness, fatigue, vertigo, nausea, vomiting, diarrhea, confusion. Contact with eyes causes irritation. Prolonged contact with skin may produce various skin eruptions, dizziness, cramps, nausea, and mild to severe disturbance of the nervous system. (USCG, 1999)

使用Sodium Thiocyanate is used widely in chemical synthesis as source of thiocyanate anion such as in the conversion of alkyl halides to alkylthiocyanates.
一般的な説明Odorless white solid. Sinks and mixes with water.
製造方法Sodium thiocyanate is prepared by boiling an aqueous solution of sodium cyanide with sulfur: NaCN + S → NaSCN.
純化方法It is recrystallised from EtOH or Me2CO, and the mother liquor is removed from the crystals by centrifugation. It is very deliquescent and should be kept in an oven at 130o before use. It can be dried in a vacuum at 120o/P2O5 [Partington & Winterton Trans Faraday Soc 30 1104 1934]. Its solubility in H2O is 113% at 10o, 178% at 46o, 225.6% at 101.4o; in MeOH 35% at 15.8o, 51% at 48o, 53.5% at 52.3o; in EtOH 18.4% at 18.8o, 24.4% at 70.9o; and in Me2CO 6.85% at 18.8o and 21.4% at 56o [Hughes & Mead J Chem Soc 2282 1929]. Sodium thiocyanate has also been recrystallised from water, acetonitrile or from MeOH using Et2O for washing, then dried at 130o, or dried under vacuum at 60o for 2days. [Strasser et al. J Am Chem Soc 107 789 1985, Szezygiel et al. J Am Chem Soc 91 1252 1987.] (The latter purification removes material reacting with iodine.) Sodium thiocyanate solutions can be freed from traces of iron by repeated batch extractions with Et2O.

Intensity of effects will vary with concentration of the solution. Inhalation of vapor causes irritation of nose and throat. Ingestion of large doses causes vomiting, extreme cerebral excitement, convulsions, and death in 10-48 hrs.; chronic poisoning can cause flu-like symptoms, skin rashes, weakness, fatigue, vertigo, nausea, vomiting, diarrhea, confusion. Contact with eyes causes irritation. Prolonged contact with skin may produce various skin eruptions, dizziness, cramps, nausea, and mild to severe disturbance of the nervous system. (USCG, 1999)

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. Special Hazards of Combustion Products: Irritating oxides of sulfur and nitrogen may form in fire (USCG, 1999). Carbonyl sulfide is produced in a violent reaction by the mixture of sulfuric acid and sodium thiocyanate.
