ʻO ka sodium thiocyanate CAS 540-72-7
He kristal kala ʻole ka sodium thiocyanate me 2 mau ʻāpana wai kristal. Ma 30.4 ℃, nalowale kona wai kristal a lilo i sodium thiocyanate anhydrous, kahi mea hiki ke hoʻoheheʻe ʻia i ka wai a me ka ethanol. Hana ʻia ia e ka distillation azeotropic o ka sodium cyanide a me ka slurry sulfur i ka ʻoihana, a ʻo ia kekahi o nā huahana hoʻomaʻemaʻe o ke kinoea umu coke i nā mea kanu coking. Hana ʻia ia mai ka wai ʻōpala o ke ʻano waikawa anthraquinone disulfonic.

Hiki ke hoʻohana ʻia ka sodium thiocyanate ma ke ʻano he reagent analytical, e like me ka hoʻoholo ʻana o ka niobium i ke kila a no ka hana ʻana i nā thiocyanates organik no ke kālā, ke keleawe, a me ka hao. Hiki ke hoʻohana ʻia ka sodium thiocyanate ma ke ʻano he solvent no ke kaha kiʻi ʻana i nā fibers polyacrylonitrile, kahi mea hana kiʻiʻoniʻoni kala, kekahi mau mea hoʻopau lāʻau, a me kahi herbicide alanui kahua mokulele.
Hoʻopili pinepine ʻia i loko o 25kg / pahu, a hiki ke hana ʻia kahi pūʻolo i hoʻopilikino ʻia.
