Iithegi zeMveliso

Yintoni iSodium thiocyanate CAS 540-72-7?

I-sodium thiocyanate yikristale engenambala equlethe iindawo ezi-2 zamanzi ekristale. Kwi-30.4 ℃, ilahlekelwa ngamanzi ayo ayikristale kwaye ibe yi-anhydrous sodium thiocyanate, enyibilikayo emanzini nakwi-ethanol. Iveliswa yi-azeotropic distillation ye-sodium cyanide kunye ne-sulfur slurry kwishishini, kwaye yenye yeemveliso zokuhlanjululwa kwegesi ye-oven ye-coke kwizityalo zokupheka. Iveliswa kulwelo lwenkunkuma anthraquinone disulfonic acid indlela.

Isicelo

I-sodium thiocyanate ingasetyenziswa njenge-reagent yokuhlalutya, njengokumisela i-niobium kwintsimbi kunye nokuveliswa kwe-organic thiocyanates yesilivere, ubhedu kunye nentsimbi. I-sodium thiocyanate inokusetyenziselwa ukunyibilikisa ukuzoba iifayibha ze-polyacrylonitrile, i-ejenti yokulungisa ifilimu ngombala, i-defoliants ethile yezityalo, kunye ne-airbicide yendlela yesikhululo seenqwelomoya.
