Sodium i-cyanide (I-NaCN) yikhompawundi enetyhefu ebaluleke kakhulu izicelo zemizi-mveliso, kodwa ikwabeka imingcipheko enzulu ngenxa yobutyhefu bayo. Ukuqonda iimpawu zayo zomzimba, ezifana ne Indawo yokunyibilika kwaye indawo yokubilisa, ibalulekile ekuphatheni ngokukhuselekileyo kunye nokusetyenziswa ngokufanelekileyo kwiinkqubo ezahlukeneyo zoshishino. Ke, yintoni kanye kanye indawo yokunyibilika kunye neyokubilisa sodium cyanide?
Indawo yokunyibilika kwe Isodium cyanide malunga ne-563.7 °C (1.046.7 °F). Kobu bushushu, buqinile Isodium cyanide utshintsho kwimo yolwelo. Indawo yokubila yesodium cyanide ijikeleze i-1.496 °C (2.725 °F). Xa ifudunyezwa kobu bushushu, ulwelo lwesodium cyanide luba ngumphunga lujike lube yigesi.
Ezi ngongoma zokunyibilika kunye nokubilisa zisisiphumo sebhondi eyomeleleyo ye-ionic ngaphakathi kwe-sodium cyanide crystal lattice. I-sodium cyanide iyikhompawundi ye-ionic eyenziwa yi-reaction ye-sodium ions (Na +) kunye ne-cyanide ions (CN-). Umtsalane we-electrostatic phakathi kwee-ion zesodium ezichajiwe kakuhle kunye neeyoni zecyanide ezihlawuliswa kakubi kudala isakhiwo esizinzileyo esifuna umthamo omkhulu wamandla ukuze siphuke, okukhokelela kumanqaku aphezulu okunyibilika kunye nokubila.
Ngenxa yamanqaku ayo aphezulu okunyibilika kunye nokubilisa, i-sodium cyanide ihlala izinzile phantsi kweemeko eziqhelekileyo zendawo. Nangona kunjalo, xa isesichengeni sobushushu obuphezulu, ngakumbi kufutshane okanye ngaphezulu kwendawo yokubila kwayo, inokukhupha igesi eyityhefu yehydrogen cyanide, eyingozi kakhulu kwimpilo yabantu nakwimekobume.
Kwiimeko zoshishino, apho i-sodium cyanide isetyenziselwa iinkqubo ezifana negolide kunye nesilivere ye-extraction, i-electroplating, kunye ne-chemical synthesis, i-protocols eqinile yokhuseleko isendaweni yokukhusela ukuvezwa ngengozi kunye nokukhululwa kwezinto ezinobuthi. Abasebenzi abaphatha i-sodium cyanide kufuneka baqeqeshwe kakuhle kwaye baxhotyiswe ngezixhobo ezifanelekileyo zokuzikhusela.
Ukuqukumbela, indawo enyibilikayo ye-sodium cyanide imalunga ne-563.7 ° C, kwaye indawo yayo yokubilisa ijikeleze i-1.496 ° C. Ezi mpawu zomzimba zibalulekile ukwazi kuye nabani na osebenza okanye ofunda le khompawundi ukuqinisekisa ukhuseleko kunye nokusetyenziswa ngendlela eyiyo.
