piav qhia
Difluoromethane yog xim tsis muaj xim, nplaim taws nrog me ntsis ether-zoo li tsw. Nws raug xa mus ua cov roj liquefied nyob rau hauv nws tus kheej vapor siab. Difluoromethane, tseem hu ua difluoromethylene, HFC-32 Methylene Fluoride los yog R-32, yog cov organic compound ntawm dihalogenoalkane ntau yam. Nws muaj cov qauv ntawm CH2F2. Nws yog cov roj uas tsis muaj xim nyob rau hauv qhov chaw ib puag ncig thiab yog me ntsis soluble hauv dej, nrog lub siab thermal stability.Vim qhov qis melting thiab boiling point, (-136.0 ° C thiab -51.6 ° C feem) kev sib cuag nrog cov compound no tej zaum yuav ua rau muaj kev kub ntxhov. frostbite.Difluoromethane feem ntau siv rau hauv cov txheej txheem endothermic xws li tub yees lossis cua txias.Difluoromethane feem ntau yog tsim los ntawm cov txheej txheem batch, los ntawm cov tshuaj tiv thaiv ntawm dichloromethane thiab hydrogen fluoride (HF), nyob rau hauv cov kua theem siv SbCl5 raws li ib tug catalyst.Difluoromethane feem ntau yog siv. Raws li kev tua hluav taws vim nws muaj peev xwm ua rau cov txheej txheem endothermic.Lwm cov kev siv ntawm difluoromethane suav nrog nws siv los ua aerosol propellants, tshuab tshuab, thiab cov kuab tshuaj.
Daim ntawv thov
Difluoromethane (CH2F2) yog siv rau hauv plasma etching ntawm silicon txheej.
