Boiling point ntawm dichloromethane: kev pom thiab kev siv
Dichloromethane, nrog rau cov tshuaj formula CH₂Cl₂, yog cov kua tsis muaj xim, muaj ntxhiab tsw qab uas tau siv dav hauv kev lag luam thiab chaw soj nstuam. Raws li ib qho tseem ceeb organic hnyav, nws plays lub luag haujlwm tseem ceeb hauv ntau cov txheej txheem tshuaj vim nws cov khoom tshwj xeeb. Hauv daim ntawv no, peb yuav ua tib zoo saib qhov tob ntawm qhov kub ntawm methylene chloride thiab txheeb xyuas nws qhov tseem ceeb hauv kev siv tswv yim.
Txheej txheem cej luam ntawm Boiling Point ntawm Methylene Chloride
Methylene chloride muaj qhov kub ntawm 39.6 ° C. Qhov kub kub kub kub no ua rau nws tsis hloov pauv ntawm chav tsev kub. Dichloromethane muaj qhov kub siab qis dua li ntau lwm cov kuab tshuaj organic, yog li nws yog feem ntau xaiv rau cov txheej txheem uas yuav tsum tau ceev evaporation ntawm cov kuab tshuaj. Qhov kub kub no ua rau methylene chloride zoo heev rau cov kuab tshuaj rov qab thiab cov txheej txheem kom qhuav, tso cai rau evaporation kom tiav.
Cov yam ntxwv cuam tshuam rau qhov kub kub ntawm methylene chloride
Txawm hais tias methylene chloride muaj qhov kub ntawm 39.6 ° C, qhov kub no tsis zoo li qub. Lub boiling point tuaj yeem cuam tshuam los ntawm ntau yam, xws li atmospheric siab, purity thiab lwm yam khoom hauv qhov sib tov. Ntawm tus qauv atmospheric siab, lub boiling point ntawm methylene chloride yog ruaj khov. Thaum lub atmospheric siab hloov, piv txwv li nyob rau hauv high altitudes, lub boiling point txo me ntsis. Lub purity ntawm methylene chloride kuj cuam tshuam rau nws qhov kub thiab txias, thiab muaj cov impurities tuaj yeem ua rau muaj qhov hloov pauv me me hauv qhov kub kub.
Dichloromethane boiling point nyob rau hauv industrial daim ntaub ntawv
Dichloromethane yog dav siv nyob rau hauv kev lag luam vim nws tsis tshua muaj boiling point, tshwj xeeb tshaj yog nyob rau hauv extraction thiab tu txheej txheem. Vim nws muaj peev xwm evaporate sai thiab nws zoo solubility, methylene chloride feem ntau yog siv nyob rau hauv extraction txheej txheem rau roj, resins thiab lwm yam organic tebchaw. Hauv kev lag luam kws tshuaj, nws yog siv los ua cov kuab tshuaj kom tshem tawm cov khoom xyaw nquag thiab hauv kev npaj cov khoom kawg kom sai sai tshem tawm cov kuab tshuaj residual los xyuas kom meej cov khoom purity.
Cov ntsiab lus
Methylene chloride muaj qhov kub ntawm 39.6 ° C, uas ua rau nws yog ib qho hnyav hnyav hauv kev lag luam tshuaj. Kev nkag siab thiab paub txog cov yam ntxwv ntawm cov dej kub npau npau ntawm methylene chloride tuaj yeem pab cov kws kho mob hauv kev lag luam kom tsim tau zoo dua thiab txhim kho cov txheej txheem ntau lawm. Hauv kev siv tswv yim, kev ua kom zoo dua ntawm qhov kub ntawm cov tshuaj methylene chloride ua ke nrog cov kev hloov hauv ib puag ncig thiab purity ntawm cov khoom tuaj yeem txhim kho cov txheej txheem kev ua tau zoo thiab cov khoom zoo.
