Kev tshuaj xyuas kev siv thiab kev tsim khoom ntawm Sodium Cyanide

Sodium cyanide, tseem hu ua sodium hydrocyanide, yog cov tshuaj lom neeg. Nws muaj ntau yam kev siv, tab sis tib lub sijhawm, nws yog nrog rau kev txaus ntshai heev. Yog li ntawd, nws cov txheej txheem ntau lawm thiab siv yuav tsum tau ceev faj tshwj xeeb.

Kev siv Sodium Cyanide

1. Hlau ua thiab Electroplating： Sodium cyanide yog siv dav hauv cov khoom siv Kev ua hlau kev lag luam, tshwj xeeb tshaj yog nyob rau hauv lub Electroplating txheej txheem. Nws tuaj yeem siv los ua ib feem ntawm cov tshuaj electroplating los pab tsim kom muaj zog thiab corrosion-resistant txheej ntawm cov hlau nto, txhim kho qhov zoo thiab kev ua neej ntawm cov khoom hlau.

2. Organic Synthesis: Hauv Organic Synthesis, Sodium Cyanide yog ib qho tseem ceeb raw khoom siv los npaj ib tug series ntawm cov organic tebchaw, xws li amino acids, amides, thiab tshuaj. Nws cov khoom siv tshuaj ua rau nws yog ib qho tseem ceeb hauv kev sib xyaw ua ke.

3. Kev Lag Luam Kev Lag Luam: Hauv dyeing thiab kho ntaub, sodium cyanide tuaj yeem siv los ua cov tshuaj ntxuav tes kom tshem tawm cov impurities thiab xim ntawm textiles.

4. Dej Khib Nyiab Kev Kho Mob： Sodium cyanide kuj tseem siv rau hauv kev kho dej khib nyiab, tshwj xeeb tshaj yog hauv kev kho cov dej khib nyiab uas muaj cov pa phem hlau hnyav, vim tias nws tuaj yeem tsim cov dej khov ruaj khov nrog cov hlau hnyav ions, yog li ntxuav cov dej.

Txawm tias Sodium cyanide muaj ntau yam kev siv nyob rau hauv cov teb no, nws cov kev siv kuj yog nrog los ntawm ib tug high degree ntawm txaus ntshai vim hais tias nws yog ib tug tsis tshua muaj tshuaj lom. Kev saib xyuas hnyav thiab ntsuas kev nyab xeeb yuav tsum tau ua thaum tuav thiab khaws cia kom ntseeg tau tias cov neeg ua haujlwm tsis raug mob.

Kev tsim khoom ntawm Sodium Cyanide

Kev tsim cov sodium cyanide feem ntau suav nrog cov kauj ruam hauv qab no:

1. Kev npaj dej Ammonia： Thawj kauj ruam hauv kev tsim cov sodium cyanide yog kev npaj cov dej ammonia. Qhov no feem ntau yog kis ammonia roj los ntawm dej thiab tom qab ntawd ua rau nws nrog nitric acid los tsim cov dej ammonia.

2. Kev npaj Hydrogen CyanideTom ntej no, ammonia dej reacts nrog formaldehyde rau daim ntawv Hydrogen Cyanide hmoov. Qhov no yog ib kauj ruam txaus ntshai vim tias cov pa roj hydrogen cyanide yog tshuaj lom heev.

3. Kev nqus ntawm Hydrogen Cyanide： Hydrogen cyanide yog absorbed rau hauv cov tshuaj alkaline, feem ntau yog sodium hydroxide (sodium hydroxide tov).

4. Cov dej nag ntawm Sodium Cyanide： Hydrogen cyanide reacts nrog sodium carbonate hauv cov tshuaj alkaline los tsim sodium cyanide. Qhov no yog cov khoom kawg ntawm sodium cyanide, tab sis ua tib zoo ua haujlwm tseem yuav tsum tau ua kom tsis txhob muaj qhov seem ntawm hydrogen cyanide.

Hauv kev xaus, sodium cyanide yog ib qho tshuaj tseem ceeb nrog ntau yam kev siv, tab sis nws yuav tsum tau tsim thiab siv nyob rau hauv kev saib xyuas zoo heev kom muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig. Nyob rau hauv txhua qhov xwm txheej uas siv sodium cyanide, kev ntsuas kev nyab xeeb thiab kev tswj hwm nruj yuav tsum tau ua raws li txhawm rau txo qhov pheej hmoo.
