Sodium thiocyanate CAS 540-72-7
ʻO ka sodium thiocyanate he aniani kala ʻole i loaʻa nā ʻāpana ʻelua o ka wai aniani. Ma 30.4 ℃, nalowale kona wai aniani a lilo i ka sodium thiocyanate anhydrous, hiki ke hoʻoheheʻe ʻia i ka wai a me ka ethanol. Hana ʻia ia e ka azeotropic distillation o ka sodium cyanide a me ka sulfur slurry 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 ka anthraquinone disulfonic acid method.

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 mea hoʻoheheʻe no ke kaha kiʻi ʻana i nā fibers polyacrylonitrile, kahi mea hana kiʻiʻoniʻoni kala, kekahi mea kanu defoliants, a me kahi herbicide alanui mokulele.
Hoʻopili pinepine ʻia i ka 25kg / pahu, a hiki ke hana ʻia i ka pōʻai maʻamau.
