Kusungunuka: kusasungunuka m'madzi ndi kusungunuka mu phenol, aldehyde, ketone, glacial acetic acid, triethyl phosphate, ethyl acetoacetate, ndi cyclohexane;kusakaniza ndi kupasuka ndi ena chlorinated hydrocarbon zosungunulira ethyl mowa, diethyl ether, ndi N, N-dimethylformamide;
Kukhazikika: Pa kutentha kwabwino (kutentha kwa chipinda) ndipo pamene palibe chinyezi, dichloromethane imakhala yokhazikika kuposa zinthu zofanana (chloroform ndi carbon tetrachloride);
Kuwola kovulaza: Ngati madzi alumikizana ndi madzi kwa nthawi yayitali, amawola pang'onopang'ono ndikupanga hydrogen chloride;
Polima wowopsa: sizichitika
Cholinga cha dichloromethane:
Dichloromethane imatha kusungunuka kwambiri ndipo imakhala ndi poizoni wochepa;amagwiritsidwa ntchito kwambiri popanga filimu yotetezeka ndi Makrolon;zotsalirazo zimagwiritsidwa ntchito posungunulira utoto, zitsulo zosungunulira zitsulo, utsi ndi jekeseni wa gasi, polyurethane kuwomba wothandizira, kumasula ndi chochotsera utoto;
Dichloromethane ndi madzi opanda mtundu.Amagwiritsidwa ntchito ngati anachita sing'anga mu makampani pharmacy ndi ntchito yokonza penbritin, carbenicillin, cephalosporin, etc., kuti zosungunulira kubala filimu, mafuta dewaxing zosungunulira, aerosol propellant, organic kaphatikizidwe m'zigawo wothandizila, polyurethane ndi thovu wothandizila ndi zina. chotsukira zitsulo popanga pulasitiki ya thovu.
