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. Alkalinity : He kumu ikaika ka sodium cyanide. Hiki iā ia ke hoʻopau i nā hopena waikawa a hana i ka waikawa hydrocyanic (HCN) i loko o ka wai:

NaCN + H₂O → HCN + NaOH

ʻO kēia ka mea e hana ai ka sodium cyanide i kahi hana koʻikoʻi i nā hopena neutralization acid-base.

2. Nā Hana o ka Ion Cyanide：ʻO ka hana kemika nui o ka sodium cyanide e pili ana i ka Ion Cyanide (CN⁻). Hiki i kēia ion ke komo i nā hana he nui, me nā hana kālā, nā hana keleawe, a me ke gula ʻana i ka metala. No ka laʻana, ʻo ka hana ʻana me nā ion kālā (Ag⁺) e hana i ka cyanide kālā precipitable (AgCN).

3. ʻAkika : He ʻawahia loa ka sodium cyanide a me kāna hopena wai no ka mea hiki i ka ion cyanide ke hoʻopaʻa i nā ion hao i loko o nā cell, e hoʻopilikia ana i ke kaʻina hana hanu cell. ʻO kēia ka mea e lilo ai ka sodium cyanide i mea nui loa i ka noiʻi toxicology.

Nā noi hoʻokolohua

1. Hana ʻana i ka Metala : Hoʻohana ʻia ka sodium cyanide i ka hana ʻana i ka Metala no ka Electroplating a me ka wehe ʻana i nā oxides o luna. 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 Loiloi : Hoʻohana pinepine ʻia ka sodium cyanide i ke Kemika Loiloi , ʻoi aku hoʻi i ka loiloi ʻana i nā paʻakai kālā. Hiki iā ia ke kōkua i ka ʻike ʻana i ke alo o ke kālā, ke keleawe, a me nā iona metala ʻē aʻe.

3. Hana ʻOkanika：Hoʻohana ʻia ka sodium cyanide ma ke ʻano he kumu a mea hoʻoulu paha i ka Hana ʻOkanika . Hiki iā ia ke komo i nā ʻano hana like ʻole, e like me ka hana Ullmann a me ka hana ʻana o nā reagents Grignard.

4. Noiʻi Toxicology : Ma muli o kona ʻawahia, hoʻohana ʻia ka sodium cyanide i ka noiʻi toxicology e aʻo ai i ke ʻano o ka hana o nā mea make a me nā ʻano hana 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.
