Sodium thiocyanate CAS 540-72-7
Sodium thiocyanate crystal ce mara launi mai ɗauke da sassa 2 na ruwan kristal. A 30.4 ℃, yana rasa ruwan kristal kuma ya zama sodium thiocyanate anhydrous, wanda ke narkewa cikin ruwa da ethanol. Ana samar da shi ta hanyar azeotropic distillation na sodium cyanide da sulfur slurry a masana'antu, kuma yana daya daga cikin samfuran tsarkakewa na coke tanda gas a cikin tsire-tsire. An samar da shi daga sharar ruwa na hanyar anthraquinone disulfonic acid.
