Sodium thiocyanate CAS 540-72-7
Sodium thiocyanate ni kirisiti itagira ibara irimo ibice 2 byamazi ya kirisiti. Kuri 30.4 ℃, itakaza amazi ya kirisiti kandi ihinduka sodium thiocyanate ya anhydrous, ikabura mumazi na Ethanol. Ikorwa na azeotropic distillation ya sodium cyanide na sulfur slurry mu nganda, kandi nikimwe mubicuruzwa bisukura gaze ya feri ya kokiya mu bimera bya kokiya. Ikorwa mumazi yimyanda ya anthraquinone disulfonic acide.

Sodium thiocyanate irashobora gukoreshwa nka reagent yisesengura, nko kumenya niobium mu byuma ndetse no gukora thiocyanate kama ya feza, umuringa, nicyuma. Sodium thiocyanate irashobora kandi gukoreshwa nkigisubizo cyo gushushanya fibre polyacrylonitrile, umukozi utunganya firime yamabara, bimwe mubihingwa byangiza, hamwe nicyatsi kibisi cyindege.
Mubisanzwe bipakiye muri 25kg / ingoma, kandi birashobora no gukora pake yabigenewe.
