Kub taw tes ntawm acetoniturile: tsom xam cov khoom tseem ceeb ntawm lub cev thiab cov ntawv thov kev lag luam
Acetonitrile yog ib hom tshuaj pleev xim rau cov tshuaj lom neeg ch₃cn.as ib cov kuab tshuaj polar, acetonitrile yog siv dav hauv cov tshuaj, tshuaj, thiab kev lag luam tshuaj. To taub cov khoom siv lub cev ntawm acetoniturile, tshwj xeeb tshaj yog cov boiling taw tes ntawm acetoniturile, yog qhov tseem ceeb heev rau nws daim ntawv thov. Hauv daim ntawv no, txoj kev npau taws ntawm cov acetoniturile thiab nws qhov tseem ceeb hauv kev lag luam yuav sib tham hauv qhov tob.
Cov Khoom Yooj Yim thiab Kev Npau Suav Bhaub Ntawm Acetonitrile
Acetonitrile yog qhov ua tsis muaj kob thiab pob tshab nrog cov xim zoo nkauj, yog li nws tuaj yeem yaj ntau lub ncov qaumteb qab zib thiab tsis muaj ntau lub ncov qaumteb qab zib. Acetonitrile muaj lub ntsiab lus npau npau ntawm 81.6 ° C, qhov kub thiab txias uas yog qhov tseem ceeb hauv kev ua haujlwm chemical. Acetonitrile tsawg lub boiling point ua rau nws yooj yim kom yaj ntawm chav tsev kub thiab siab, ua rau nws muaj ntau yam uas yuav tsum tau ziab kom qhuav lossis volatilisation.
Qhov tseem ceeb ntawm Acetonitrile npau taw rau hauv cov ntawv thov solvent
Acetonitrile yog dav siv los ua cov kuab tshuaj hauv chromatographic analalyzes xws li kev ua kom zoo kua chromatography (HPLC). Nyob rau hauv HPLC, qhov cub kub ntawm cov kuab tshuaj cuam tshuam kev xaiv ntawm mobile theem thiab kev sib cais ua haujlwm. Vim tias qhov qis boiling taw tes ntawm acetoniturile, nws tuaj yeem ua kom tau evaporated sai, txo qis thiab txhim kho cov qauv huv. Kev siv cov acetoniturile nyob rau hauv tshuaj lom neeg tshuaj lom neeg kuj tso siab rau nws cov yam ntxwv npau npau. Piv txwv li, hauv qee qhov hluavtaws cov tshuaj tiv thaiv qhov ntsuas kub xav tau los tswj hwm tau los ua cov acetonitrile tuaj yeem siv los ua cov tshuaj tiv thaiv cov tshuaj tiv thaiv.
Boiling taw tes tswj ntawm acetonitrile hauv kev lag luam ntau lawm
Hauv kev tsim khoom thiab khaws cov acetoniturile, kev tswj ntawm boiling taw tes ntawm acetonitrile yog qhov tseem ceeb heev. Txij li cov acetonitrile muaj lub tshuab hluav taws xob siab, ntsuas qhov ntsuas kub hnyiab tau los tiv thaiv nws cov txheej txheem ntau dhau, uas tuaj yeem cuam tshuam rau cov txiaj ntsig thiab qhov zoo. Thaum khaws cov acetoniturile, feem ntau nws yog qhov yuav tsum muaj nyob rau hauv qhov chaw kub tsawg lossis kaw ib puag ncig kom txo qis cov roj ntsha tsis muaj kev tiv thaiv thiab ua kom muaj kev nyab xeeb.
Kev Nyab Xeeb thiab ib puag ncig kev txiav txim siab ntawm Acetonitrile Npau Suav Boiling
Cov tshuab hluav taws xob ntawm acetonitrile ua rau nws qhov cub npau npau yog qhov tseem ceeb hauv kev nyab xeeb thiab ib puag ncig kev txiav txim siab. Thaum tuav thiab siv cov acetoniturile, nws cov volatility yuav tsum txiav txim siab los tiv thaiv kom nqus tau pa ntawm cov pa roj acetonitrile siab. Kev paub txog ntawm lub boiling taw tes ntawm acetonitrile tuaj yeem pab txhim kho cov tswv yim volatile zoo (voc
Lub ntsiab
Kev paub txog lub qhov cub npau tes ntawm acetonitrile yog qhov tseem ceeb rau nws cov ntawv thov kev lag luam. Txawm li cas los xij hauv kev tsim khoom, cia lossis siv, lub boiling taw qhia ncaj qha cuam tshuam rau kev nyab xeeb, kev tiv thaiv thiab ib puag ncig kev ua haujlwm. Yog li ntawd, hauv kev lag luam tshuaj, them sai sai rau qhov npau taws ntawm cov acetonitrile yog ib qho ntawm cov yuam sij los xyuas kom txoj kev du ntawm cov txheej txheem.
