I-Sodium Cyanide: Iipropati, iiNgozi, kunye neMiqathango yoKhuseleko

intshayelelo

Sodium i-cyanide (I-NaCN) yikhompawundi ye-inorganic edlala indima ebalulekileyo kwizicelo ezahlukeneyo zoshishino. Nangona kunjalo, indalo yayo enetyhefu kakhulu ifuna ukuphathwa ngokungqongqo kunye neeprothokholi zokhuseleko. Eli nqaku liphonononga iipropati, ukusetyenziswa, kunye neengozi ezinokubakho ezinxulumene nazo Isodium cyanide.

Iipropati zeMichiza kunye nezoMzimba

Ifomula yeMichiza kunye noLwakhiwo

I-sodium cyanide inefomyula yekhemikhali i-NaCN. Yikhompawundi ye-ionic eyenziwe yi-sodium cation (Na⁺) kunye ne-cyanide anion (CN⁻). Kwisakhiwo sekristale, ii-ion ze-sodium kunye ne-cyanide zicwangciswe kwi-lattice efana neye-sodium chloride. ICarbon iathom kwiqela le-cyanide yenza i-triple bond kunye ne-nitrogen atom, nto leyo enika i-CN⁻ ion indlela esebenza ngayo.

Ubume beMpawu

• Kubonakala: Isodium cyanide ibonakala imhlophe, ikristale eqinileyo okanye umgubo.

• Iphunga: Kwimo yayo eyomileyo, ihlala ingenavumba. Nangona kunjalo, xa idibana nokufuma emoyeni okanye emanzini, inokuvelisa igesi ye-hydrogen cyanide (HCN), ene-almond epholileyo - efana nevumba. Kubalulekile ukuba uqaphele ukuba akuyena wonke umntu onokubona iphunga le-hydrogen cyanide, njengoko ukukwazi ukwenza oko kunqunywe ngokwemfuza.

• Amanqaku anyibilikayo kunye nokubilisa: Inomlinganiselo ophezulu wokunyibilika we-563.7 °C kunye neqondo lokubila lika-1496 °C.

• Umzimba: Isodium cyanide inyibilika kakhulu emanzini. Enyanisweni, i-38.9 grams ye-NaCN inokunyibilika kwi-100 mililitha yamanzi kwi-20 °C. Ikwanyibilika kwezinye izinyibilikisi zepolar ezifana neammonia, ethanol, kunye nemethanol.

I-Chemical Reactivity

• Ukuhanjiswa kwegesi: I-sodium cyanide yityuwa ye-asidi ebuthakathaka, i-hydrogen cyanide (HCN). Xa idibana namanzi, ingena kwi-hydrolysis, ivelisa igesi ye-hydrogen cyanide. I-equation yeekhemikhali yale mpendulo yile: NaCN + H₂O ⇌ NaOH + HCN. Le ndlela yokusabela inokwenzeka nokuba kumanzi asemkhathini, okwenza kube qinileyo Isodium cyanide umthombo onokubakho wokukhupha igesi eyityhefu.

• Iimpendulo ze-Acid: Isabela ngokukhawuleza kunye neeasidi. Ngokomzekelo, nini sodium cyanide isabela nge-asidi ye-sulfuric (H₂SO₄), le mpendulo ilandelayo yenzeka: 2NaCN + H₂SO₄ → Na₂SO₄ + 2HCN. Ukukhutshwa kwegesi ye-hydrogen cyanide kwiimpendulo ezinjalo kuyingozi kakhulu ngenxa yetyhefu ephezulu.

• Metal Complex Formation: I-sodium cyanide inobudlelwane obuqinileyo besinyithi. Phambi kweoksijini kunye namanzi, inokunyibilikisa iintsimbi ezixabisekileyo njengegolide nesilivere. Kwigolide, impendulo ihamba ngolu hlobo lulandelayo: 4Au + 8NaCN + O₂ + 2H₂O → 4Na[Au(CN)₂] + 4NaOH. Le propati ixhatshazwa ngokubanzi kwishishini lemigodi ukuze kuthathwe igolide.

Ukulungiselela

Kumashishini, i-sodium cyanide iveliswa ikakhulu kukusabela kwe-hydrogen cyanide (HCN) kunye ne-sodium hydroxide (NaOH). I-equation yeekhemikhali yale mpendulo yile: HCN + NaOH → NaCN + H₂O. I-Hydrogen cyanide inokuveliswa ngeendlela ezahlukeneyo, ezifana nenkqubo ye-Andrussow, ebandakanya ukusabela kwe-methane (CH₄), i-ammonia (NH₃), kunye ne-oxygen (O₂) phezu kweplatinum - i-rhodium catalyst kumaqondo aphezulu okushisa.

Usebenzisa

Icandelo lezemigodi

Esinye sezona zicelo zibalulekileyo zesodium cyanide kukutsalwa kwegolide nezinye iintsimbi ezixabisekileyo kwiore. Inkqubo, eyaziwa ngokuba Cyanidation, kubandakanya ukusetyenziswa kwezisombululo ze-sodium cyanide zokunyibilikisa igolide kunye nesilivere kwi-ores yazo. Iintsimbi ezinyityilisiweyo ziye zifumaneke ngothotho lweenkqubo zemichiza. Le ndlela isetyenziswa ngokubanzi ngenxa yokusebenza kakuhle kunye neendleko eziphantsi xa kutsalwa iintsimbi ezixabisekileyo kwi-ores yodidi oluphantsi.

Ukuveliswa kweMichiza

Isodium cyanide isebenza njengendawo ebalulekileyo ephakathi kwimveliso yoluhlu olubanzi lweekhompawundi zemichiza. Isetyenziselwa ukuhlanganiswa kwee-nitriles, ezizibhloko ezibalulekileyo zokwakha kumashishini amayeza, i-agrochemical, kunye ne-polymer. Ngokomzekelo, isetyenziselwa ukuvelisa i-cyanuric chloride, ephinda isetyenziswe ekwenzeni imichiza yokutshabalalisa ukhula, izibulali-ntsholongwane, kunye nedayi yelaphu.

I-Electroplating

Kumzi-mveliso we-electroplating, i-sodium cyanide isetyenziswa kwezinye iibhafu zokucoca, ngakumbi ukufakwa kwesinyithi njengobhedu, isilivere, negolide. Inceda ekubunjweni kwengubo efanayo kunye nokubambelelayo kwentsimbi kwi-substrate. Iiyoni ze-cyanide kwindawo yokuhlambela edibeneyo kunye neeyoni zetsimbi, ziququzelela ukubekelwa komgangatho ogudileyo kunye nentsimbi.

Iingozi Zempilo

Ityhefu Mechanism

Isodium cyanide inetyhefu kakhulu. Xa ifakwe, ifakwe, okanye ifakwe esikhumbeni, iyahlukana nokukhupha i-cyanide ions (CN⁻). Ezi ion ze-cyanide zibophelela kwi-iron(III) kwi-cytochrome c oxidase, i-enzyme kwi-mitochondria yeeseli. Oku kubopha kuthintela umsebenzi we-enzyme, ukuthintela ukuhanjiswa kwee-electron kwikhonkco lokuthutha i-electron. Ngenxa yoko, iiseli azikwazi ukusebenzisa i-oksijini ngokufanelekileyo, okukhokelela kwimeko ye-asphyxiation yeselula. Kwanomlinganiselo omncinci wesodium cyanide unokubulala.

Iziphumo eziNgxamisekileyo zokuVezwa

• Ukungenisa: Ukungena kwi-sodium cyanide kunokukhokelela ekuqaliseni ngokukhawuleza kweempawu. Iimpawu zokuqala zingabandakanya ukutshisa emlonyeni nasemqaleni, kulandele isicaphucaphu, ukuhlanza, iintlungu zesisu kunye norhudo. Njengoko ityhefu ihambela phambili, kusenokuba nzima ukuphefumla, ukubetha kwentliziyo ngokukhawuleza okanye okungaqhelekanga, isiyezi, intloko ebuhlungu nokudideka. Iimeko ezimandundu zinokubangela ukuxhuzula, ukulahlekelwa zingqondo, kunye nokufa kwimizuzu ukuya kwiiyure.

• Inhalation: Ukusezela igesi yehydrogen cyanide, enokukhutshwa kwisodium cyanide xa kukho ukufuma okanye iiasidi, nako kuyingozi kakhulu. Iimpawu zokuvezwa kokuphefumla zinokubandakanya ukucaphuka kwendlela yokuphefumla, ukukhohlela, ukuphefumla kancinci, ukuxinezeleka kwesifuba, kunye nemvakalelo yokufuthaniselwa. Ukuphefumla kwinqanaba eliphezulu kunokukhokelela ekubanjweni kokuphefumla kunye nokufa.

• Ukuqhagamshelana nolusu kunye neliso: Ukudibana ngokuthe ngqo ne-sodium cyanide kunokubangela ukucaphuka kunye nokutshisa kwesikhumba kunye namehlo. Uqhagamshelwano olude okanye olubanzi lwesikhumba lunokuvumela ukuba i-cyanide ifakwe egazini, ekhokelela kwi-systemic poisoning.

Iimpembelelo zokuSebenza okuNgapheliyo

Ukubonakaliswa okungapheliyo kumanqanaba aphantsi e-sodium cyanide akuxhaphakanga kangako kodwa kusenokuba neempembelelo ezimbi kakhulu kwimpilo. Inokubangela iimpawu ezinjengobuthathaka, ukudinwa, intloko ebuhlungu, iingxaki zenkumbulo, nomonakalo kwidlala lengqula. Ukuvezwa kwexesha elide kunokonyusa umngcipheko wokukhula kokuphazamiseka kwemithambo-luvo kwaye kunokuba neziphumo ezibi kwiinkqubo zentliziyo kunye nezokuphefumla.
