Sodium thiocyanate CAS 540-72-7
Sodium thiocyanate ndi kristalo yopanda mtundu yokhala ndi magawo awiri a madzi a kristalo. Pa kutentha kwa 30.4 ℃, imataya madzi ake a kristalo ndipo imakhala sodium thiocyanate yosasungunuka, yomwe imasungunuka m'madzi ndi ethanol. Imapangidwa ndi azeotropic distillation ya sodium cyanide ndi sulfure slurry m'mafakitale, ndipo ndi imodzi mwa zinthu zoyeretsera mpweya wa coke mu coking plants. Imapangidwa kuchokera ku zinyalala za anthraquinone disulfonic acid.

Sodium thiocyanate ingagwiritsidwe ntchito ngati choyezera, monga kudziwa niobium mu chitsulo komanso kupanga organic thiocyanate ya siliva, mkuwa, ndi chitsulo. Sodium thiocyanate ingagwiritsidwenso ntchito ngati chosungunulira pokoka ulusi wa polyacrylonitrile, choyezera utoto wa filimu, mankhwala ena ochotsera zomera, ndi mankhwala ophera tizilombo toyambitsa matenda pamsewu wa pa eyapoti.
Kawirikawiri amanyamula mu 25kg/ng'oma, ndipo amathanso kupangidwa mwamakonda.
