Cov ncauj lus kom ntxaws tsom xam ntawm Boiling Point ntawm Triethylamine
Triethylamine (TEA luv luv) yog ib qho organic compound uas belongs rau amine chav kawm ntawm cov tshuaj. Nws yog dav siv nyob rau hauv ntau industries xws li tshuaj, tshuaj tua kab, dyes, solvents thiab hais txog. Raws li kev siv tshuaj lom neeg, lub cev lub cev ntawm Triethylamine, tshwj xeeb tshaj yog nws cov ntsiab lus kub, yog qhov tsis zoo uas yuav tsum tau nkag siab meej thiab tswj tau hauv ntau cov txheej txheem tshuaj. Nyob rau hauv daim ntawv no, peb yuav tham txog lub boiling point ntawm triethylamine nyob rau hauv kom meej, soj ntsuam lub physicochemical vim li cas tom qab nws, thiab nws qhov tseem ceeb nyob rau hauv kev siv tswv yim.
Txheej txheem cej luam ntawm lub boiling point ntawm triethylamine
Lub boiling point ntawm triethylamine yog 89.5 ° C (193.1 ° F), uas yog nws boiling kub ntawm tus qauv atmospheric siab (1 atm). Lub boiling point yog qhov kub ntawm lub vapor siab ntawm ib tug kua yog sib npaug zos rau sab nraud siab, txhais tau hais tias nyob rau hauv no kub triethylamine hloov los ntawm ib tug kua lub xeev mus rau lub gaseous lub xeev. Boiling point yog ib qho tseem ceeb ntawm lub cev ntawm ib yam khoom thiab yog qhov tseem ceeb rau kev nkag siab txog tus cwj pwm ntawm triethylamine nyob rau hauv ntau yam mob.
Cov yam ntxwv cuam tshuam rau lub boiling point ntawm triethylamine
Lub boiling point ntawm triethylamine yog feem ntau cuam tshuam los ntawm nws cov qauv molecular thiab intermolecular rog. Triethylamine yog tertiary amine uas nws cov qauv molecular muaj nitrogen atom txuas rau peb pawg ethyl. Vim tias tsuas muaj ib khub ntawm electrons ntawm nitrogen atom hauv triethylamine molecule, nws tsis yooj yim rau triethylamine los tsim hydrogen bonds. Qhov no ua rau cov rog sib xyaws ntawm triethylamine feem ntau yog van der Waals rog, uas tsis muaj zog. Yog li ntawd, lub boiling point ntawm triethylamine kuj tsawg.
Cov saw hlau hydrocarbon nyob rau hauv lub triethylamine molecule yog me ntsis hydrophobic, uas kuj muaj kev cuam tshuam rau nws cov boiling point. Triethylamine muaj qhov hnyav molecular piv rau lwm cov organic amines zoo sib xws, uas yog ib feem piav qhia nws qhov qis qis. Kev sib xyaw ua ke ntawm cov qauv molecular thiab intermolecular rog ntawm triethylamine txiav txim siab nws qhov kub ntawm 89.5 ° C. Lub boiling point ntawm triethylamine kuj yog ib tug muaj nuj nqi ntawm lub molecular qauv ntawm amine.
Qhov tseem ceeb ntawm lub boiling point ntawm triethylamine nyob rau hauv industrial daim ntaub ntawv
Nws yog ib qho tseem ceeb kom nkag siab thiab tswj qhov kub ntawm triethylamine hauv cov txheej txheem tshuaj lom neeg. Txij li thaum lub boiling point ntawm triethylamine nyob ze rau 90 ° C, kev sib cais zoo thiab purification ntawm triethylamine tuaj yeem ua tiav los ntawm kev kho qhov kub thiab txias thaum lub sij hawm cov tshuaj tiv thaiv thiab kev sib cais. Piv txwv li, thaum lub sij hawm distillation, precisely tswj qhov kub nyob ze ntawm lub boiling point ntawm triethylamine yuav zoo cais nws los ntawm lwm cov tebchaw nrog txawv boiling ntsiab lus. Paub txog qhov kub thiab txias ntawm triethylamine kuj tseem ceeb heev rau kev ua haujlwm nyab xeeb kom tsis txhob muaj qhov tsis zoo ntawm qhov poob lossis kev nyab xeeb vim qhov kub thiab txias.
Xaus
Triethylamine muaj qhov kub ntawm 89.5 ° C. Cov cuab yeej ntawm lub cev no yog txiav txim siab los ntawm nws cov qauv molecular thiab intermolecular rog. Hauv kev lag luam tshuaj, kev tswj xyuas meej ntawm qhov boiling point ntawm triethylamine yog qhov tseem ceeb rau kev tsim khoom thiab kev nyab xeeb. Kev nkag siab txog qhov kub ntawm triethylamine tsis tsuas yog pab txhim kho cov txheej txheem ntau lawm, tab sis kuj tseem muab cov lus qhia tseem ceeb hauv kev ua haujlwm.
