Boiling taw tes ntawm dichhloromethane: kev nkag siab thiab kev siv
Dichhloromethane, nrog cov tshuaj siv tshuaj ch₂cclula, yog cov kua tsis muaj kob, cov kua qab zib uas tau siv dav hauv kev lag luam thiab chaw soj ntsuam. Raws li ib qho tseem ceeb Organic kuab tshuaj, nws plays lub luag haujlwm tseem ceeb hauv ntau cov txheej txheem tshuaj lom neeg vim nws cov khoom tshwj xeeb. Hauv daim ntawv no, peb yuav siv sij hawm tob tob ntawm qhov npau taws ntawm methylene chloride thiab txheeb xyuas nws qhov tseem ceeb hauv kev siv cov kev siv.
Txheej txheem cej luam ntawm lub boiling qhov ntev ntawm methylene chloride
Methylene chloride muaj qhov cub npau npau ntawm 39.6 ° C. Qhov no tsawg tshaj kub point ua rau nws tsis zoo ntawm chav tsev kub. Dichhloromethane muaj qhov qis dua npau npau dua li ntau lwm cov kuab tshuaj organic, yog li nws feem ntau tau xaiv rau cov txheej txheem uas yuav tsum tau kho nrawm nrawm ntawm cov kuab tshuaj. Qhov no tsis tshua yog boiling point ua rau methylene chloride zoo heev rau cov kuab tshuaj rov qab zoo thiab cov txheej txheem kom qhuav, tso cai rau evaporation kom ua tiav.
Yam cuam tshuam rau txoj kev npau npau ntawm methylene chloride
Txawm hais tias Methylene chloride muaj qhov cub npau npau ntawm 39.6 ° C, qhov kub no tsis yog li qub. Lub Bushing point tuaj yeem cuam tshuam los ntawm ntau tus yam, xws li cov kev ua kom siab, huv thiab lwm yam hauv qhov sib xyaw. Ntawm cov qauv cua ntawm cov qauv siab, qhov npau taws ntawm methylene chloride yog qhov ruaj khov. Thaum lub siab hloov pauv, piv txwv li ntawm Altitudes High, lub boiling point tsawg zuj zus me ntsis. Kev ua kom huv ntawm methylene chloride tseem cuam tshuam nws lub ntsej muag npau npau, thiab muaj cov impurities yuav ua rau cov kev hloov pauv me me hauv qhov cub npau npau.
Dichhloromethane Boiling taw tes rau hauv kev siv cov ntawv thov
Dichhloromethane tau siv dav hauv kev lag luam vim nws qhov chaw npau npau tsawg, tshwj xeeb tshaj yog nyob rau hauv extraction thiab tu cov txheej txheem. Vim nws muaj peev xwm ua kom yaj sai thiab nws cov solubility zoo, methylene chloride feem ntau yog siv rau cov roj, cov dab tsi thiab lwm cov organic teb. Hauv kev lag luam kws tshuaj, nws yog siv los ua cov kuab tshuaj kom nquag plias cov khoom xyaw kom sai sai muab cov khoom siv nrawm nrawm.
Lub ntsiab
Methylene chloride muaj qhov cub npau npau ntawm 39.6 ° C, ib qho cuab yeej uas ua rau nws muaj kev lag luam tsis tseem ceeb hauv kev lag luam tshuaj. Nkag siab thiab txawj lub taw kev cuam tshuam ntawm methylene chloride tuaj yeem pab cov kws kho tshuaj lom neeg ua haujlwm zoo dua thiab tsim cov txheej txheem ntau lawm. Hauv cov ntawv thov siv tau, siv kom zoo dua ntawm cov methylene chloride nrog rau kev hloov pauv ntawm cov txheej txheem ib puag ncig thiab cov khoom siv tau txhim kho cov txheej txheem kev ua haujlwm zoo thiab cov khoom lag luam zoo.
