Dichloromethane Density Analysis
Dichloromethane, nrog rau cov tshuaj formula CH2Cl2, tseem hu ua methylene chloride, yog cov organic hnyav siv dav hauv tshuaj, tshuaj, xim stripper, degreaser thiab lwm yam. Nws lub cev muaj zog, xws li qhov ceev, qhov kub thiab txias, qhov chaw melting, thiab lwm yam, yog qhov tseem ceeb rau nws cov ntawv thov kev lag luam. Hauv daim ntawv no, peb yuav txheeb xyuas kom meej txog cov khoom tseem ceeb ntawm lub cev ntawm qhov ntom ntom ntawm dichloromethane thiab tshawb xyuas nws cov kev hloov pauv hauv cov xwm txheej sib txawv.
Lub ntsiab lus tseem ceeb ntawm dichloromethane ntom ntom
Qhov ntom ntawm dichloromethane yog ib qho tseem ceeb ntawm lub cev uas ntsuas qhov loj ntawm ib chav tsev ntim ntawm cov khoom. Raws li kev sim cov ntaub ntawv ntawm cov txheej txheem (piv txwv li, 25 ° C), qhov ceev ntawm methylene chloride yog kwv yees li 1.325 g / cm³. Tus nqi ntom ntom no tso cai rau methylene chloride ua haujlwm zoo sib cais los ntawm dej, roj tshuaj thiab lwm cov kuab tshuaj organic hauv cov ntawv thov kev lag luam. Vim nws qhov ntom ntom ntau dua li dej (1 g / cm³), methylene chloride feem ntau tso rau hauv qab ntawm cov dej, uas pab tswj cov kua-kua sib cais los ntawm tus neeg siv los ntawm kev sib cais cov khoom xws li dispensing funnels.
Cov nyhuv ntawm qhov kub ntawm qhov ntom ntawm methylene chloride
Qhov ceev ntawm methylene chloride hloov nrog kub. Feem ntau, qhov ntom ntawm ib yam khoom txo qis thaum qhov kub thiab txias nce, vim qhov kev txav ntawm molecular ntau ntxiv, uas ua rau nthuav dav ntawm cov khoom ntim. Nyob rau hauv cov ntaub ntawv ntawm methylene chloride, ntawm qhov kub thiab txias qhov ceev yuav qis dua me ntsis ntawm chav tsev kub. Yog li ntawd, nyob rau hauv kev lag luam kev lag luam, cov neeg siv yuav tsum tau kho qhov ceev ntawm methylene chloride rau tej yam kub thiab txias los xyuas kom meej qhov tseeb ntawm cov txheej txheem.
Cov nyhuv ntawm lub siab ntawm qhov ntom ntawm methylene chloride
Txawm hais tias qhov cuam tshuam ntawm qhov ceev ntawm cov kua yog me me piv rau qhov kub thiab txias, qhov ntom ntawm methylene chloride tseem tuaj yeem hloov me ntsis hauv qhov siab. Nyob rau hauv cov xwm txheej kub siab heev, qhov kev ncua deb ntawm intermolecular raug txo, uas ua rau muaj kev nce hauv qhov ntom ntom. Hauv cov ntawv thov kev lag luam tshwj xeeb, xws li kev kub siab rho tawm lossis cov txheej txheem tshuaj tiv thaiv, nws yog ib qho tseem ceeb kom nkag siab thiab xam cov nyhuv ntawm qhov ceev ntawm methylene chloride.
Dichloromethane ceev vs. Lwm cov kuab tshuaj
Txhawm rau kom nkag siab zoo dua lub cev ntawm methylene chloride, nws qhov ntom ntom feem ntau yog piv rau lwm cov kuab tshuaj organic. Piv txwv li, ethanol muaj qhov ceev ntawm 0.789 g / cm³, benzene muaj qhov ceev ntawm 0.874 g / cm³, thiab chloroform muaj qhov ceev ze li 1.489 g / cm³. Nws tuaj yeem pom tau tias qhov ntom ntawm methylene chloride nyob ntawm cov kuab tshuaj no thiab hauv qee qhov sib xyaw ua ke qhov sib txawv ntawm qhov ntom ntom tuaj yeem siv rau kev sib cais thiab kev xaiv zoo.
Qhov tseem ceeb ntawm dichloromethane ceev rau kev siv tshuab
Dichloromethane ntom ntom muaj qhov cuam tshuam loj rau nws cov ntawv thov kev lag luam. Nyob rau hauv daim ntawv thov scenarios xws li hnyav extraction, tshuaj synthesis, tshuaj ntxuav, thiab lwm yam, dichloromethane ceev txiav txim seb nws cuam tshuam nrog lwm yam tshuaj. Piv txwv li, hauv kev lag luam kws tshuaj, methylene chloride qhov ntom ntom ua rau nws zoo tagnrho rau cov txheej txheem rho tawm. Vim nws qhov siab ceev, methylene chloride cais tawm sai sai ntawm cov dej theem thaum lub sij hawm muab faib ua haujlwm, txhim kho cov txheej txheem kev ua haujlwm.
Cov ntsiab lus
Los ntawm kev txheeb xyuas qhov ceev ntawm methylene chloride, peb tuaj yeem pom tias nws qhov ntom ntom ua lub luag haujlwm tseem ceeb hauv kev siv tshuab. Kev nkag siab thiab kev paub txog kev hloov pauv ntawm dichloromethane ntom ntom hauv qhov sib txawv ntawm qhov kub thiab txias tuaj yeem pab txhim kho cov txheej txheem tsim thiab txhim kho kev tsim khoom. Txawm nyob hauv chav kuaj lossis hauv kev tsim khoom, cov ntaub ntawv ceev ceev yog lub hauv paus rau kev ua kom muaj kev vam meej ntawm cov txheej txheem tshuaj. Yog li, kev tshawb fawb tob txog qhov ntom ntom ntawm methylene chloride yog qhov tseem ceeb heev rau cov kws kho mob kev lag luam.
