Dichloromethane (DCM), tseem hu ua methylene chloride, yog denser dua dej. Nyob ib ncig ntawm 20 degree, nws qhov ceev yog hais txog1.32-1.33g / cm³, thaum dej yog hais txog1.00 g / cm³.
Qhov sib txawv tsuas yog los ntawm qhov muaj pes tsawg leeg thiab cov qauv ntawm ob lub kua. DCM muaj ob chlorine atoms nyob rau hauv txhua molecule, muab nws ntau dua molecular hnyav dua dej. Molecular loj thiab txoj kev ntawm cov molecules ntim hauv cov kua kuj cuam tshuam qhov ntom.
Vim li cas Dichloromethane ntom dua dej?
Cov mis molecular ntawm dichloromethane yogCH₂Cl₂, nrog ib qho hnyav molecular txog84,93 g / mol. Dej, lossis H₂O, muaj qhov hnyav molecular txog18.02 g / mol.
Ob lub chlorine atoms suav rau feem ntau ntawm cov molecular loj ntawm DCM. Tab sis qhov hnyav molecular tsis yog vim li cas rau nws qhov ceev dua. Qhov ntom yog nyob ntawm ob qho tib si loj thiab qhov ntim ntawm cov molecules, nrog rau lawv cov kev cuam tshuam hauv cov kua.
Yog li, cov lus piav qhia yooj yim yog tias DCM muaj ntau ntau ntim rau hauv cov ntim zoo li dej. Cov chlorine atoms yog ib feem tseem ceeb ntawm qhov sib txawv, tab sis lawv tsis yog tag nrho cov lus piav qhia.
Puas yog Dichloromethane hnyav dua dej?
Yog lawm. Ib qho ntim ntawm DCM hnyav dua li tib lub ntim dej.
| Khoom | Dichloromethane | Dej |
|---|---|---|
| Formula | CH₂Cl₂ | H₂O |
| Molecular hnyav | 84,93 g / mol | 18.02 g / mol |
| Qhov ceev ntawm ~ 20 degree | 1.32-1.33g / cm³ | ~ 1.00 g/cm³ |
Qhov no yog vim li cas DCM feem ntau tau piav qhia tias yog cov organic hnyav hnyav hauv kev siv tswv yim.
Vim li cas DCM Sink hauv dej?
Thaum DCM thiab dej sib cais ua ob txheej kua,DCM feem ntau tsim cov txheej hauv qabvim nws yog denser tshaj dej.
Qhov no muaj txiaj ntsig zoo hauv cov kua - kua extraction. Tom qab sib xyaw cov theem aqueous nrog DCM thiab tso cai rau qhov sib xyaw kom haum, DCM- theem nplua nuj tuaj yeem pom nyob hauv qab.
Ob lub kua dej tsis yog miscible kiag li. DCM muaj kev txwv tsis pub solubility hauv dej, uas tso cai rau cov theem sib cais los ua raws li cov xwm txheej tsim nyog.
Puas yog DCM Ua Tus Kheej txhais tau tias Nws Dissols Zoo hauv dej?
Tsis muaj.Qhov ntom thiab solubility yog ob yam khoom sib txawv.
DCM yog denser dua dej tab sis tsuas yog ib nrab soluble hauv nws. Qhov ceev txiav txim siab seb theem twg nyob rau saum lossis hauv qab tom qab sib cais, thaum solubility piav qhia tias DCM nkag mus rau theem dej ntau npaum li cas.
Rau kev xaiv cov kuab tshuaj, ob qho tib si yuav tsum tau txiav txim siab sib cais.
Vim li cas DCM Qhov Tseem Ceeb Tseem Ceeb rau Cov Neeg Yuav Khoom?
DCM density cuam tshuam rau theem kev sib cais, ntim- mus rau- hnyav hnyav thiab hnyav tuav hauv cov ntawv thov kev lag luam.
Rau cov neeg yuav khoom yuav ntau dichloromethane, qhov ceev kuj tseem tuaj yeem pab hloov ntawm qhov ntim thiab qhov hnyav thaum ntsuas nruas, IBCs lossis cov khoom xa tuaj loj.
Txawm li cas los xij, qhov ceev yuav tsum tsis yog qhov tseem ceeb thaum xaiv DCM tus neeg muag khoom. Cov neeg yuav khoom yuav tsum tau paub meej tias purity, specification, ntim, SDS, TDS, COA thiab shipping yuav tsum.
FAQ
Puas yog Dichloromethane ntom dua dej?
Yog lawm. DCM muaj qhov ceev ntawm txog1.32-1.33 g / cm³ ntawm 20 degree, piv nrog kwv yees li 1.00 g / cm³ rau dej.
Vim li cas DCM Denser dua dej?
DCM muaj qhov hnyav molecular ntau dua li dej, feem ntau vim tias txhua lub molecule muaj ob chlorine atoms. Nws cov qauv molecular thiab ntim rau hauv cov kua kuj tseem ua rau muaj qhov ntom ntom dua.
Puas yog Dichloromethane Sink lossis ntab hauv dej?
DCM feem ntau tso dej thiab tsim cov txheej txheem qis vim tias nws qhov ntom ntom yog siab dua li cov dej.
Dab tsi yog qhov ntom ntawm Methylene Chloride?
Methylene chloride yog lwm lub npe rau dichloromethane. Nws qhov ceev yog kwv yees li1.32-1.33 g / cm³ ntawm 20 degree.
