Difluoromethane ni gaze itagira ibara, yaka umuriro hamwe numunuko muto wa ether. Yoherejwe nka gaze isukuye munsi yumuvuduko wacyo. Difluoromethane, nanone yitwa difluoromethylene, HFC-32 Methylene Fluoride cyangwa R-32, ni ifumbire mvaruganda y'ubwoko bwa dihalogenoalkane. Ifite formula ya CH2F2. Ni gaze itagira ibara mukirere kidasanzwe kandi irashobora gushonga gake mumazi, hamwe nubushyuhe bwinshi bwumuriro.Kubera aho gushonga no guteka, (-136.0 ° C na -51,6 ° C bikurikiranye) guhura nuru ruganda bishobora kuvamo ubukonje.Difluoromethane ikunze gukoreshwa mubikorwa bya endothermic nko gukonjesha cyangwa guhumeka ikirere.Difluoromethane ikomatanyirizwa cyane hakoreshejwe inzira, hamwe na reaction ya dichloromethane na fluoride hydrogène (HF), mugice cyamazi ukoresheje SbCl5 nkumusemburo.Difluoromethane ikoreshwa kenshi. nk'ikizimya umuriro bitewe nubushobozi bwayo bwo gukora endothermic.Ubundi buryo bwo gukoresha difluoromethane burimo no gukoresha nka moteri ya aerosol, ibyuma bisohora, hamwe na solve.
Porogaramu
Difluoromethane (CH2F2) ikoreshwa muri plasma yohasi ya silicon.
