Imbali, iEvolution, kunye neSimo sangoku seSodium Cyanide

intshayelelo

I-Sodium cyanide (NaCN), ityuwa enobungozi kakhulu kwi-inorganic, idlale indima ebalulekileyo kumashishini aqala kwimigodi ukuya kumayeza. Eli nqaku lilandela iingcambu zalo zembali, liphonononga ukuvela kwalo kwimizi-mveliso, kwaye lihlola indawo yalo yangoku kwixesha eligxile ekuzinzeni.

1. Imvelaphi yembali

I-sodium cyanide yaqala ukwenziwa phakathi kwinkulungwane ye-19, yaqala ukuba yinxalenye ebalulekileyo ye-reagent yokucubungula nokukhupha isinyithi . Uphuhliso lwayo lwafika kwicandelo lemigodi yegolide, apho yaba yinto ebalulekileyo yokwahlula igolide nesilivere kwi-ore ngenkqubo ye -cyanidation.

Ngasekupheleni kwee-1800s, ushishino lwandise ukusetyenziswa kwalo ukuya kuthi ga:

• Ukuveliswa kwedayi

• Ukwenziwa kwerabha yokwenziwa

• Uphuhliso lwezitshabalalisi

  
  

  
  

2. 20th-Century Evolution

Nangona ubuthi beSodium Cyanide bufuna imigaqo engqongqo yokhuseleko, ukusetyenziswa kwayo kwabangela ukuba isetyenziswe ngokubanzi:

Izicelo eziphambili

1. Ukwemba : Kuye kwahlala kukusetyenziswa kakhulu ekutsaleni igolide, nto leyo evumela ukufunyanwa ngokufanelekileyo kweentsimbi ezikumgangatho ophantsi.

2. I-Organic Chemistry : Isebenza njenge-catalyst okanye i-intermediate kwiimpendulo ezifana nokuhlanganiswa kwe-nitrile.

3. Amayeza : Asetyenziswa ekuvelisweni kwamayeza afana ne-acetazolamide (i-diuretic).

Iinkxalabo zoLawulo ziyavela

Ukukhula kolwazi malunga nemingcipheko yendalo esingqongileyo kunye nempilo kukhokelele ekubeni:

• Umthetho : Amazwe afana ne-US neKhanada anyanzelisa imithetho engqongqo yokugcina, ukuthuthwa, kunye nokulahla izinto.

• Imigangatho yoShishino : Ukwamkelwa kweenkqubo zokhuseleko ukunciphisa ukuvezwa ngengozi.

3. Imbonakalo-mhlaba yangoku (kwiNkulungwane yama-21)

Namhlanje, indima ye -sodium cyanide ibunjwa ziinjongo zokuzinza kunye nophuhliso lwetekhnoloji:

1. IiTekhnoloji ezizezinye

• Ukumbiwa Okuluhlaza : Uphando malunga nezinto ezingeyotyhefu (umz., ukuleaching kwe-thiosulfate) lujolise ekunciphiseni ukuxhomekeka kwi-cyanide.

• Iindlela Ezinokubola : Uphuhliso lwee-chelating agents ezinobuhlobo nokusingqongileyo zokukhupha isinyithi.

2. Imigaqo engqongqo

• Ukuthobela iMithetho yeHlabathi : Amazwe anyanzelisa imigangatho ye-ISO 14001 kunye ne-REACH ukunciphisa umonakalo odalwe yindalo esingqongileyo.

• Ukulandelela ngeDijithali : Izixhobo zeBlockchain kunye ne-IoT ziphucula ukucaca kwekhonkco lokubonelela.

3. Uphando kunye neMfundo

• Uqeqesho loKhuseleko : Iinkqubo ezinyanzelekileyo zabasebenzi bemizi-mveliso abaphatha i-NaCN.

• Amanyathelo Ezemfundo : Iiyunivesithi zisebenzisana namashishini ukuze kuhlolwe iindlela ezikhuselekileyo zokudibanisa.

isiphelo

Ukususela ekufumanekeni kwayo kwinkulungwane ye-19 ukuya ekusetyenzisweni kwayo namhlanje, iSodium cyanide isasoloko iyinto engaqhelekanga: sisixhobo esibalulekileyo semizi-mveliso esineengozi ezikhoyo. Nangona ezinye iindlela kunye nemithetho zizama ukunciphisa umngcipheko wayo kwindalo, indima yayo engenakutshintshwa kumacandelo afana nemigodi iqinisekisa ukusetyenziswa kwayo okuqhubekayo—nangona igxile kakhulu kukhuseleko kunye nokuzinza.
