Kub taw tes ntawm Acetoniturile: Qhov tseem ceeb ntawm lub cev parameter hauv kev lag luam chemical
Acetoniturile, raws li ib qho tseem ceeb Organic kuab tshuaj hauv kev lag luam tshuaj, tshuaj kho yeeb tshuaj thiab kua checomatography txheeb xyuas. Mastering tus cwj pwm lub cev ntawm acetonitrile yog qhov tseem ceeb rau nws daim ntawv thov hauv kev lag luam, ntawm cov uas npau npau yog ib qho tseem ceeb tshaj plaws. Hauv daim ntawv no, txoj kev npau taws ntawm cov acetoniturile yuav raug tshuaj xyuas kom meej, thiab cov cawv ntawm cov ntsuas no rau kev ua haujlwm chemical.
Boiling taw tes ntawm acetoniturile thiab nws qhov cuam tshuam
Qhov npau taws ntawm cov acetonitrile feem ntau yog 81.6 ° C (txog 179 ° F), thiab qhov kub thiab txias thiab lwm yam kev sib cais hauv cov txheej txheem tshuaj lom neeg. Qhov npau taws ntawm cov acetonitrile cuam tshuam los ntawm ntau yam, suav nrog kev ua siab dawb, kev coj dawb huv, thiab sib xyaw nrog lwm cov tshuaj. Feem ntau, qhov npau taws ntawm cov acetonitrile yog tus qauv nyob rau hauv cov qauv atmospheric siab, tab sis yog tias lub siab hloov, lub rwj yuav hloov tau. Piv txwv li, nyob rau hauv kev txo qis, qhov npau npau ntawm cov acetonitrile txo qis, thiab sib tham, nyob rau hauv cov xwm txheej uas muaj kuab, lub boiling point nce. Cov xeeb ceem no ua rau acetoniturile muaj cov ntawv thov dav dav nyob rau hauv cov txheej txheem sib txawv.
Qhov tseem ceeb ntawm boiling taw tes ntawm acetonitrile nyob rau hauv kev lag luam cov ntawv thov
Kev paub txog qhov npau taws ntawm cov acetonitrile yog ib qho tseem ceeb siv tau rau cov qauv ua haujlwm siv tshuaj. Hauv kev lag luam ntau lawm, nws yog feem ntau tsim nyog los cais tov tov, thiab cov tshuaj ntsuas npau npau ua rau nws yog cov tshuaj zoo tshaj plaws hauv cov txheej txheem ntawm cov kuab tshuaj rov qab. Piv txwv li, hauv cov kua chromatography kev txheeb xyuas, cov kev kub npau npau ua rau nws ua kom yaj ntawm qhov kub thiab txias, ua kom muaj kev cuam tshuam ntawm cov qauv. Hauv cov tshuaj ntsuam xyuas hluavtis, tswj cov tshuaj tiv thaiv kub txav ze rau lossis hauv qab qhov npau taws ntawm acetonitrile pab kom muaj kev nyab xeeb ntawm cov tshuaj tiv thaiv thiab kev coj dawb huv ntawm cov khoom.
Kev siv lub rwj kub ntawm acetonitrile los ua kom zoo dua cov txheej txheem ntau lawm
Los ntawm kev paub thiab nkag siab txog lub rwj ntawm cov acetoniturile, engineers tuaj yeem txhim kho cov txheej txheem ntau lawm los txhim kho cov nqi ua tau zoo thiab txo tus nqi. Piv txwv li, nyob rau hauv cov txheej txheem distillation, txoj kev npau taws ntawm acetonitrile tuaj yeem siv ua qhov kev ua haujlwm ntawm cov kem distillation kom ntseeg tau kev sib cais zoo. Los ntawm kev kho lub kaw lus siab hloov pauv qhov npau npau ntawm cov acetoniturile, nws yog qhov ua tau kom yooj yim dua kev ua haujlwm nyob rau hauv cov txheej txheem sib txawv. Hom no tsis tuaj yeem tsuas yog txuag lub zog, tab sis kuj txhim kho kev nyab xeeb thiab kev ruaj khov ntawm tag nrho cov kab.
Lub ntsiab
Qhov kub npau suav ntawm acetonitrile yog qhov tseem ceeb ntawm lub cev tsis muaj tshuaj lom neeg hauv kev lag luam kev lag luam, uas cuam tshuam nrog ntau yam tshuaj lom neeg. Pib los ntawm cov khoom tseem ceeb ntawm acetoniturile, kev nkag siab tob ntawm cov txheej txheem boils thiab nws cov khoom lag luam zoo dua qub cov khoom lag luam muaj txiaj ntsig zoo thiab ua tiav lub hom phiaj ntawm kev loj hlob. Los ntawm kev nkag siab zoo thiab thov cov boiling taw tes ntawm acetoniturile, cov tuam txhab chemical muaj peev xwm coj kom zoo dua ntawm kev sib tw ua lag luam tau zoo.
