Nā Pono Kemika a me nā noi hoʻokolohua o ka sodium cyanide

ʻO ka sodium cyanide kahi pūhui inorganic me nā waiwai kemika kū hoʻokahi a hoʻohana nui ʻia i nā laboratories a me ka hana ʻoihana. E ʻimi kēia ʻatikala i nā waiwai kemika o ʻO ka sodium Cyanide a me kāna kuleana ma nā noi hoʻokolohua.

Nā Kino

ʻO ka sodium cyanide he aniani keʻokeʻo, maʻamau i ke ʻano paʻa. He paʻa ia ma ka lumi wela, akā ma lalo o ka hoʻomehana a i ʻole nā ​​kūlana haʻahaʻa kiʻekiʻe, e decomposes i loko o ka waika hydrocyanic a me ka sodium hydroxide. ʻO NaCN kona kumu hoʻohālike kemika, a ʻo kona nuipa molar he 49.01 g/mol.

Nā Pono Kemika

1.Alkalina：He kumu ikaika ka sodium cyanide. Hiki iā ia ke hoʻokaʻawale i nā hopena ʻakika a hana i ka waika hydrocyanic (HCN) i ka wai:

NaCN + H₂O → HCN + NaOH

keia i ka sodium cyanide pāʻani koʻikoʻi i ka ʻakika - base neutralization reactions.

2. Nā hana o ka Cyanide Ion：Pili ka hana kemika nui o ka sodium cyanide i ka Cyanide Ion (CN⁻). Hiki i kēia ion ke komo i nā hopena he nui, e like me ke kala kala, ke keleawe, a me ka metala gilding. No ka laʻana, ʻo ka pane ʻana me nā ion kālā (Ag⁺) e hana i ka cyanide kālā precipitable (AgCN).

3. ʻO ka ʻawaʻawa： ʻO ka sodium cyanide a me kāna ʻano wai he mea ʻawaʻawa loa no ka mea hiki i ka cyanide ion ke hoʻopaʻa i nā ion hao i loko o nā cell, ke keʻakeʻa nei i ke kaʻina hana hanu cell. Hana kēia i ka sodium cyanide i mea koʻikoʻi i ka noiʻi toxicology.

Nā noi hoʻokolohua

1.Metal ProcessingHoʻohana ʻia ka sodium cyanide i loko Hoʻonohonoho Metal no ka mea, Ke kohopiliʻana a me ka wehe ʻana i nā oxides ili. Hiki ke hoʻohana ʻia e electroplate i nā metala makamae e like me ke gula a me ke kālā ma luna o ka ʻili o nā mea ʻē aʻe.

2. Kemika AnalyticalHoʻohana pinepine ʻia ka sodium cyanide Ke Kauka Hoʻopākiʻopili, ʻoi aku ka nui o ka nānā ʻana i nā paʻakai kālā. Hiki ke kōkua i ka ʻike ʻana i ke kālā, ke keleawe, a me nā ion metala ʻē aʻe.

3.Organic Synthesis：Hoʻohana ʻia ka sodium cyanide ma ke ʻano he kumu a i ʻole catalyst i loko ʻOihana synthes. Hiki iā ia ke komo i nā hopena like ʻole, e like me ka hopena Ullmann a me ka synthesis o Grignard reagents.

4. ʻImi Hoʻonaʻauao：Ma muli o kona ʻona, hoʻohana ʻia ka sodium cyanide i ka noiʻi toxicology e aʻo i ke ʻano o ka hana o nā mea ʻawaʻawa a me nā ʻano no ka mālama ʻana i ka lāʻau make.

Pono e hoʻomaopopo ʻia ʻo ka hoʻohana ʻana i ka sodium cyanide e hahai i nā kaʻina hana palekana, a pono e hoʻomalu pono ʻia kona ʻona. I loko o nā ʻenehana a me nā ʻenehana, pono e lawe ʻia nā hana palekana kūpono e pale aku ai i ka pili a me ka leakage. Eia kekahi, ʻo ka hoʻohana kānāwai a me ka hoʻokuʻu ʻana i ka sodium cyanide pono e hoʻokō me nā kānāwai kūpono a me nā lula e hōʻoia i ka palekana o ke olakino a me ke olakino kanaka.
