Chloroform boiling point thiab nws cov kev cuam tshuam yam tsom xam
Chloroform (Chloroform), nrog rau cov tshuaj formula CHCl₃, yog cov xim tsis muaj xim organic nrog cov ntxhiab tsw tshwj xeeb, uas yog siv dav hauv kev lag luam tshuaj thiab tshuaj. Hauv kev tsim tshuaj lom neeg, nws yog ib qho tseem ceeb heev kom nkag siab txog lub cev lub cev ntawm chloroform, uas cov ntsiab lus kub ntawm chloroform yog qhov tseem ceeb, uas cuam tshuam ncaj qha rau nws siv thiab tuav hauv qhov kub thiab txias. Daim ntawv no yuav txheeb xyuas qhov kub ntawm chloroform thiab nws cov yam ntxwv cuam tshuam hauv kev nthuav dav.
1. Txheej txheem cej luam ntawm lub boiling point ntawm chloroform
Chloroform muaj qhov kub ntawm 61.2 ° C (kwv yees li 334.35 K), uas ua rau nws ua kua hauv chav tsev kub. Vim tias nws qhov kub kub qis, chloroform nyhav evaporate ntawm chav tsev kub, uas yuav tsum tau saib xyuas tshwj xeeb thaum siv thiab khaws cia. Cov cuab yeej no ntawm qhov kub ntawm cov chloroform ua rau nws muaj txiaj ntsig hauv distillation, kev sib cais thiab kev tsim tshuaj lom neeg.
2. Cov yam ntxwv cuam tshuam rau qhov kub kub ntawm chloroform
Lub boiling point ntawm chloroform yog feem ntau cuam tshuam los ntawm ambient siab. Raws li tus qauv atmospheric siab, qhov kub ntawm chloroform yog 61.2 ° C. Thaum lub siab hloov pauv, lub boiling point ntawm chloroform kuj yuav hloov. Piv txwv li, nyob rau hauv lub siab txo, lub boiling point ntawm chloroform txo, uas yog zoo rau cov txheej txheem uas yuav tsum tau distillation ntawm tsawg kub. Ib yam li ntawd, nyob rau hauv kev kub siab, qhov kub ntawm chloroform nce, uas yuav xav tau kev txiav txim siab tshwj xeeb hauv qee cov txheej txheem kev kho mob.
Lub boiling point ntawm chloroform kuj cuam tshuam los ntawm nws purity. Chloroform uas muaj impurities tej zaum yuav muaj ib tug boiling point uas txawv ntawm cov ntshiab chloroform vim hais tias muaj impurities hloov lub volatility ntawm cov kua. Yog li ntawd, nyob rau hauv cov tshuaj zoo thiab tshuaj, purity ntawm chloroform yuav tsum tau ua kom paub tseeb tias qhov tseeb ntawm nws cov boiling point thiab lwm yam khoom ntawm lub cev.
3. Qhov tseem ceeb ntawm chloroform boiling point nyob rau hauv industrial siv
Hauv kev tsim tshuaj lom neeg, kev nkag siab qhov kub ntawm chloroform yog qhov tseem ceeb rau cov txheej txheem tsim thiab xaiv cov khoom siv. Piv txwv li, nyob rau hauv cov organic synthesis cov tshuaj tiv thaiv, cov tshuaj tiv thaiv kub feem ntau yuav tsum tau tswj nyob ze ntawm chloroform boiling point kom muaj ib tug du cov tshuaj tiv thaiv. Chloroform raws li cov kuab tshuaj uas nquag siv, nws cov ntsiab lus kub kub cuam tshuam ncaj qha rau kev rov qab los thiab rov ua haujlwm ntawm cov kuab tshuaj.
Hauv kev lag luam kws tshuaj, qhov kub ntawm chloroform kuj txiav txim siab nws qhov kev siv tau hauv qee cov txheej txheem tshuaj. Piv txwv li, thaum siv nyob rau hauv kws tshuaj los rho tawm tej yam khoom xyaw, chloroform lub boiling point tso cai rau nws mus evaporate ntawm qis kub, yog li tiv thaiv tshav kub-sensitive tshuaj.
4. Kev Tiv Thaiv Kev Nyab Xeeb Hauv Kev Siv Chloroform
Vim tias chloroform tsis hloov pauv thiab muaj tshuaj lom nyob rau hauv chav tsev kub, nws yuav tsum tau ua haujlwm thiab khaws cia nrog kev tiv thaiv kev nyab xeeb tsim nyog. Kev paub txog cov ntsiab lus kub ntawm chloroform tuaj yeem pab cov neeg ua haujlwm tswj hwm nws cov volatility thiab tsis txhob nqus pa ntau dhau. Nyob rau hauv ib puag ncig kub kub, nws yog ib qho tsim nyog yuav tsum tau xyuam xim rau qhov tsis muaj zog ntawm chloroform los tiv thaiv kev tsim cov pa roj ntau hauv huab cua, uas yuav ua rau muaj kev phom sij rau kev noj qab haus huv.

Los ntawm kev txheeb xyuas cov ncauj lus kom ntxaws ntawm cov ntsiab lus kub ntawm chloroform thiab nws cov kev cuam tshuam, nws tuaj yeem pom tau tias kev paub txog cov yam ntxwv ntawm cov dej kub npau npau ntawm chloroform yog qhov tseem ceeb heev rau kev tswj cov txheej txheem thiab cov khoom siv hauv kev tsim tshuaj. Kev nkag siab thiab tswj qhov kub ntawm chloroform yog ib kauj ruam tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab kev ua haujlwm zoo, ob qho tib si hauv kev tsim khoom thiab kev ua haujlwm hauv chav kuaj.
