Sodium thiocyanate CAS 540-72-7
Sodium thiocyanate ndi kristalo wopanda mtundu wokhala ndi magawo awiri amadzi akristalo. Pa 30.4 ℃, imataya madzi ake akristalo ndikukhala anhydrous sodium thiocyanate, yomwe imasungunuka m'madzi ndi ethanol. Amapangidwa ndi distillation ya azeotropic ya sodium cyanide ndi sulfure slurry m'makampani, ndipo ndi imodzi mwazinthu zoyeretsera mpweya wa uvuni wa coke muzomera zophika. Amapangidwa kuchokera kumadzi otayira a anthraquinone disulfonic acid njira.

Sodium thiocyanate angagwiritsidwe ntchito ngati reagent analytical, monga kutsimikiza niobium mu zitsulo ndi kupanga organic thiocyanates siliva, mkuwa, ndi chitsulo. Sodium thiocyanate itha kugwiritsidwanso ntchito ngati chosungunulira pojambula ulusi wa polyacrylonitrile, chopangira mafilimu amitundu, zowononga mbewu, ndi mankhwala ophera udzu wamsewu wa eyapoti.
Nthawi zambiri ankanyamula 25kg/ng'oma, komanso akhoza kuchita makonda phukusi.
