Dichloromethane DCM (CAS: 75-09-2) yog dab tsi?
Dichloromethane, tseem hu ua Methylene Dichloride los yog DCM, yog cov organic tsis muaj xim nrog cov ntse, ether -zoo li tsw thiab cov tshuaj formula CH₂Cl₂.
Dichloromethane (DCM) cov khoom thiab siv
DCM yog tsim los ntawm kev hloov ob lub hydrogen atoms hauv methane (CH₄) nrog cov tshuaj chlorine atoms. Nws yog me ntsis soluble hauv dej tab sis yooj yim soluble hauv ethanol thiab ether. Raws li ib txwm muaj, nws yog ib qho uas tsis yog -flammable, low- boiling hnyav; Txawm li cas los xij, nws cov vapor tuaj yeem tsim cov nplaim hluav taws tsis muaj zog hauv cov huab cua siab - kub. Vim nws cov kuab tshuaj zoo, nws feem ntau yog siv los ua lwm txoj hauv kev nyab xeeb rau cov kuab tshuaj tsw qab heev xws li roj av ether thiab diethyl ether.
Dichloromethaneyog dav siv nyob rau hauv industrial sectors raws li ib tug industrial hnyav, nruab nrab, thiab coolant. Nws tseem ua lub luag haujlwm tseem ceeb hauv kev npaj tshuaj, chaw soj nstuam, thiab kev lag luam kws tsim tshuaj.
Dab tsi yog qhov ceev ntawm dichloromethane DCM thiab dej?
Dichloromethane, DCM (CH2Cl2) hnyav dua (qhov ntom=1.3266g cm-3)) dua dej (qhov ntom=1 g cm-3). Yog li, DCM thiab H2O yuav nyob qis qis thiab sab sauv txheej raws li qhov sib cais funnel (SF).
