Thepa ea Lik'hemik'hale le Lisebelisoa tsa Teko tsa Sodium Cyanide

Sodium cyanide ke motsoako oa inorganic o nang le lik'hemik'hale tse ikhethang 'me o sebelisoa haholo lilaboratoring le tlhahiso ea indasteri. Sehlooho sena se tla hlahloba litšobotsi tsa lik'hemik'hale tsa Sodium cyanide le karolo ea eona lits'ebetsong tsa liteko.

Matlo a 'mele

Sodium cyanide ke kristale e tšoeu, hangata e teng ka sebopeho se tiileng. E batla e tsitsitse mocheso oa kamore, empa tlas'a mocheso kapa maemo a mongobo o phahameng, e senyeha ka hydrocyanic acid le sodium hydroxide. Foromo ea eona ea lik'hemik'hale ke NaCN, 'me boima ba eona ba molar ke 49.01 g / mol.

Mefuta ea Lik'hemik'hale

1. Alkalinity : Sodium cyanide ke motheo o matla. E ka fokotsa ditharollo tsa asiti mme ya hlahisa hydrocyanic acid (HCN) ka metsing:

NaCN + H₂O → HCN + NaOH

Sena se etsa hore sodium cyanide e bapale karolo ea bohlokoa liketsong tsa ho se nke lehlakore ha acid-base.

2. Likarabelo tsa Ion ea Cyanide : Mosebetsi o ka sehloohong oa lik'hemik'hale oa sodium cyanide o amana le Ion ea Cyanide (CN⁻). Ion ena e ka nka karolo liketsong tse ngata, ho kenyeletsoa le likarabelo tsa silevera, likarabelo tsa koporo, le ho bōptjoa ha tšepe. Mohlala, ho arabela ka li-ion tsa silevera (Ag⁺) ho tla etsa cyanide ea silevera e ka melang (AgCN).

3. Chefo : Sodium cyanide le tharollo ea eona ea metsi li chefo haholo hobane ion ea cyanide e ka tlama li-ion tsa tšepe liseleng, e sitisa mokhoa oa ho hema ha sele. Sena se etsa hore sodium cyanide e be ea bohlokoa bo ikhethang lipatlisisong tsa chefo.

Lisebelisoa tsa Teko

1. Ts'ebetso ea Tšepe : Sodium cyanide e sebelisoa Ts'ebetsong ea Tšepe bakeng sa ho polata ka motlakase le ho tlosa li-oxide tse holim'a metsi. E ka sebelisoa ho polata ka motlakase litšepe tsa bohlokoa tse kang khauta le silevera holim'a thepa e 'ngoe.

2. Khemistri ea Tlhahlobo : Sodium cyanide e atisa ho sebelisoa Khemistring ea Tlhahlobo , haholo-holo tlhahlobong ea letsoai la silevera. E ka thusa ho lemoha boteng ba li-ion tsa silevera, koporo le tse ling tsa tšepe.

3. Ho kopanya lintho tse phelang : Sodium cyanide e sebelisoa e le motheo kapa catalyst ho Organic Synthesis . E ka nka karolo liketsong tse fapaneng, joalo ka karabelo ea Ullmann le ho kopanya li-reagent tsa Grignard.

4. Patlisiso ea Chefo : Ka lebaka la chefo ea eona, sodium cyanide e sebelisoa lipatlisisong tsa chefo ho ithuta mokhoa oa tšebetso ea chefo le mekhoa ea ho phekola chefo.

Hoa lokela ho hlokomeloa hore tšebeliso ea sodium cyanide e lokela ho latela mekhoa ea tšireletso, 'me chefo ea eona e lokela ho laoloa ka thata. Libakeng tsa laboratori le indasteri, mehato e nepahetseng ea polokeho e lokela ho nkoa ho thibela ho kopana le ho lutla. Ho phaella moo, tšebeliso ea molao le ho lahla sodium cyanide e lokela ho lumellana le melao le litaelo tse amehang ho netefatsa polokeho ea tikoloho le bophelo ba batho.
