Indawo yokubilisa i-40 ° C. Izinyibilikisi zeqondo eliphantsi ngokupheleleyo-ezibilisayo zihlala zisetyenziselwa ukutshintshela i-ether ye-petroleum enokutsha, i-ether, njl., kwaye inokusetyenziswa njenge-anesthesia yendawo, i-refrigerant kunye ne-arhente yokucima umlilo.Indawo yokutshisa ezenzekelayo yi-640 ° C. I-Decoction (20 ° C) 0.43MPa · s.Isalathiso se-refractive nd (20 ° C) 1.4244.Ukushisa okubalulekileyo ngu-237 ° C, kwaye uxinzelelo olunzima luyi-6.0795MPa.I-HCL kunye neendlela zokukhanya ziveliswa emva kwesisombululo se-thermal, kwaye amanzi ashushu ixesha elide ukuvelisa i-formaldehyde kunye ne-HCL.I-chloride eyongezelelweyo, i-CHCL3 kunye ne-CCL4 inokufumaneka.

Inkcazo

Iipropati: I-dichloromethane ecocekileyo ayinayo i-flash point, kwaye umxube we-solvent oqukethe umthamo olinganayo we-dichloromethane kunye ne-petroli, i-solvent naphtha okanye i-toluene ayinakutsha.Nangona kunjalo, xa i-dichloromethane ixutywe ne-acetone okanye i-methanol ye-Chemicalbook liquid kwi-10: i-1 i-proportion mixing, umxube une-flash point, i-steam kunye nomoya ukwenza umxube oqhumayo, umda wokuqhuma 6.2% ~ 15.0% (umthamo).

Ukusetyenziswa kweMethylene Chloride

I-Methylene Chloride (DCM) ineenzuzo zokunyibilika okuqinileyo kunye netyhefu ephantsi.Isetyenziselwa ukwenza iimuvi ezikhuselekileyo kunye ne-polycarbonate, kwaye ezinye zisetyenziswa njenge-solvent yokugquma, i-agent yokulahla isinyithi, i-gas smoke spray, i-agent ye-polyurethane foaming, i-de-molding mold Umonakalo, i-lacquer agent.I-Dichloromethane lulwelo olungenambala, olusetyenziswa njengendlela yokusabela kwishishini lamachiza ukulungiselela i-ammonia penicillin, i-hydroxycin kunye ne-pioneecin, njl.;I-Organic synthetic extracting agents, i-polyurethane kunye nolunye ukuveliswa kweplastiki ye-foam kwii-agent ezikhupha ugwebu kunye nee-agent zokucoca isinyithi.I-Dichloromethane isetyenziswa kakhulu kwimveliso yefilimu kunye namayeza e-China.Phakathi kwazo, ukusetyenziswa kwemveliso yefilimu kubalelwa kwi-50% yokusetyenziswa iyonke, iakhawunti yeyeza ye-20Chemicalbook% yokusetyenziswa iyonke, ukusetyenziswa kwearhente yokucoca kunye neshishini lemichiza libalelwa kwi-20% yosetyenziso lulonke, kunye neminye iakhawunti. nge-10%.I-Dichloromethane ikwasetyenziswa kwiinkqubo zokukhenkcisa kwimizi-mveliso yefriji, kodwa iyingozi kakhulu kwaye inokuvelisa ukukhanya okuyityhefu xa idibana nomlilo okhanyayo okanye izinto ezivuthayo.Kwimeko yomoya ofumileyo, i-hydrolyzed hydrogen chloride ingasetyenziselwa ukukhuthaza i-hydrogen chloride, kwaye ukukhanya kunokukhuthaza i-hydrolysis kunye nokuphucula isinyithi e-corrosion.Isetyenziselwa ukupholisa i-grain fumigation kunye ne-low-voltage enomkhenkce kunye nezixhobo zokupholisa umoya.Kwimveliso ye-polyether-uhlobo lweplastiki ye-alkane yomchamo, isetyenziswa njenge-arhente encedisayo yogwebu, kunye nee-arhente ezikhupha ugwebu lokukhama iiplastiki ze-polymutra foam.IDichloromethane ikwasetyenziselwa ukwenza izinto zekofu ephelelwe ngamanzi.Ikofu iqala ukupheka ukunyibilikisa i-caffeine kwaye idada phezu komhlaba, kwaye emva koko isebenzisa i-dichloromethane ukususa i-caffeine.
