Sodium thiocyanate CAS 540-72-7
Sodium thiocyanate wani lu'ulu'u ne mara launi wanda ke ɗauke da sassa 2 na ruwan lu'ulu'u. A zafin digiri 30.4, yana rasa ruwan lu'ulu'u kuma ya zama sodium thiocyanate mai narkewa, wanda ke narkewa a cikin ruwa da ethanol. Ana samar da shi ta hanyar azeotropic distillation na sodium cyanide da sulfur slurry a masana'antu, kuma yana ɗaya daga cikin samfuran tsarkakewa na iskar gas ta coke a cikin masana'antar coking. Ana samar da shi ne daga ruwan sharar da aka yi amfani da shi na hanyar anthraquinone disulfonic acid.
