Cov khoom siv tshuaj lom neeg thiab kev sim siv ntawm Sodium Cyanide

Sodium cyanide yog ib qho inorganic compound nrog cov khoom siv tshuaj lom neeg thiab siv dav hauv cov chaw kuaj thiab kev tsim khoom. Kab lus no yuav tshawb txog cov khoom siv tshuaj lom neeg ntawm Sodium Cyanide thiab nws lub luag haujlwm hauv cov ntawv thov kev sim.

Lub Cev Lub Cev

Sodium cyanide yog siv lead ua dawb, feem ntau muaj nyob rau hauv daim ntawv. Nws yog qhov ruaj khov nyob rau hauv chav tsev kub, tab sis nyob rau hauv cua sov los yog siab - cov av noo, nws decomposes rau hauv hydrocyanic acid thiab sodium hydroxide. Nws cov qauv tshuaj yog NaCN, thiab nws cov molar loj yog 49.01 g / mol.

Tshuaj khoom

1. Alkalinity : Sodium cyanide yog lub hauv paus muaj zog. Nws tuaj yeem ua rau cov kua qaub tsis muaj zog thiab tsim cov kua qaub hydrocyanic (HCN) hauv dej:

NaCN + H₂O → HCN + NaOH

Qhov no ua rau sodium cyanide ua lub luag haujlwm tseem ceeb hauv cov tshuaj tiv thaiv acid - base neutralization.

2. Cov tshuaj tiv thaiv ntawm Cyanide Ion : Cov tshuaj lom neeg tseem ceeb ntawm sodium cyanide muaj feem cuam tshuam nrog Cyanide Ion (CN⁻). Cov ion no tuaj yeem koom nrog ntau yam tshuaj tiv thaiv, suav nrog cov tshuaj tiv thaiv nyiaj, cov tshuaj tiv thaiv tooj liab, thiab cov hlau kub. Piv txwv li, cov tshuaj tiv thaiv nrog cov ions nyiaj (Ag⁺) yuav tsim cov nyiaj cyanide uas tau los ntawm cov av noo (AgCN).

3. Kev Lom Zem： Ob qho tib si sodium cyanide thiab nws cov kua dej muaj tshuaj lom heev vim tias cov cyanide ion tuaj yeem khi rau cov hlau ions hauv cov cell, cuam tshuam rau cov txheej txheem ua pa ntawm cov cell. Qhov no ua rau sodium cyanide tseem ceeb heev hauv kev tshawb fawb txog kev lom.

Cov ntawv thov kev sim

1. Kev Ua Hlau : Sodium cyanide yog siv rau hauv Kev Ua Hlau rau Electroplating thiab tshem tawm cov oxides ntawm qhov chaw. Nws tuaj yeem siv los electroplate cov hlau muaj nqis xws li kub thiab nyiaj rau ntawm qhov chaw ntawm lwm cov ntaub ntawv.

2. Kev Tshuaj Xyuas Txog Tshuaj : Sodium cyanide feem ntau siv rau hauv Kev Tshuaj Xyuas Txog Tshuaj , tshwj xeeb tshaj yog hauv kev tshuaj xyuas cov ntsev nyiaj. Nws tuaj yeem pab nrhiav pom tias muaj nyiaj, tooj liab, thiab lwm yam hlau ions.

3. Kev Tsim Khoom Siv Organic : Sodium cyanide yog siv los ua lub hauv paus lossis catalyst hauv Kev Tsim Khoom Siv Organic . Nws tuaj yeem koom nrog ntau yam kev tshuaj tiv thaiv, xws li Ullmann tshuaj tiv thaiv thiab kev tsim cov tshuaj Grignard reagents.

4. Kev Tshawb Fawb Txog Kev Lom Zem : Vim nws muaj tshuaj lom, sodium cyanide siv rau hauv kev tshawb fawb txog kev lom neeg los kawm txog cov txheej txheem ua haujlwm ntawm cov tshuaj lom thiab cov hau kev kho mob lom.

Nws yuav tsum raug sau tseg tias kev siv sodium cyanide yuav tsum ua raws li cov txheej txheem kev nyab xeeb, thiab nws cov tshuaj lom yuav tsum tau tswj nruj me ntsis. Hauv chav kuaj thiab chaw tsim khoom, kev ntsuas kev nyab xeeb tsim nyog yuav tsum tau coj los tiv thaiv kev sib cuag thiab xau. Tsis tas li ntawd, kev siv thiab pov tseg kev cai lij choj ntawm sodium cyanide yuav tsum ua raws li cov kev cai lij choj thiab cov cai tswj xyuas kom muaj kev nyab xeeb ntawm ib puag ncig thiab tib neeg kev noj qab haus huv.
