Sodium thiocyanate CAS 540-72-7
Sodium thiocyanate o se tioata e leai ni lanu e iai vaega e 2 o vai tioata. I le 30.4 ℃, e leiloa lona vai tioata ma avea ma sodium thiocyanate anhydrous, lea e solu i le vai ma le ethanol. E gaosia e le azeotropic distillation o le sodium cyanide ma le sulfur slurry i alamanuia, ma o se tasi o oloa faamamaina o le ogaumu kasa coke i laau coking. E gaosia mai le otaota otaota o le anthraquinone disulfonic acid method.

Sodium thiocyanate e mafai ona faʻaaogaina e avea o se suʻesuʻega suʻesuʻe, e pei o le fuafuaina o le niobium i le sila ma mo le gaosiga o thiocyanates organic mo siliva, kopa, ma uʻamea. O le sodium thiocyanate e mafai foʻi ona faʻaaogaina e fai ma solu mo le tusiaina o filo polyacrylonitrile, o se vailaʻau e gaosia ata tifaga, o nisi mea e faʻamama ai laau, ma se vailaʻau o le malaevaalele.
E masani ona faʻapipiʻiina i le 25kg / paʻu, ma e mafai foi ona faia faʻapipiʻi faʻapitoa.
