Vim li cas Dichhloromethane (CAST 75-09-2) siv ib qho kev sib zog sib luag?

Dichhloromethane (DCM), tseem hu ua methylene chloride, yog cov kuab tshuaj zoo heev rau cov txheej txheem rho tawm vim nws cov khoom tshwj xeeb. Nws yog polar agor farvent, lub ntsiab lus nws muaj lub sij hawm tseem ceeb dipole, tab sis tsis muaj hydrogen atoms los koom rau hauv hydrogen bonding. Qhov no ua rau cov enables

DCM (CAS 75-09-2)Txhawm rau yaj ntau ntawm polar thiab tsis yog cov tebcuj teb chaws, ua rau nws muaj ntau yam hauv cov txheej txheem rho tawm.

Tsis tas li ntawd, DCM muaj qhov cub npau npau tsawg ntawm 39.6℃thiab yog immiscible nrog dej. Qhov no ua raws li kev sib cais ntawm cov kev rho tawm cov tebchaw los ntawm kev daws los ntawm evaporation lossis siv kev sib cais funnel. Qhov qis boiling point kuj tseem txo qhov kev pheej hmoo ntawm cov kev rho tawm cov tebchaw txuas ntxiv thermal degradation. Cov khoom siv no ua rau DichloromreMethane zoo kawg nkaus xaiv rau ntau cov txheej txheem rho tawm hauv Chemistry thiab Biochemistry.
