incazelo emfushane:

I-Methylene Chloride iyinhlanganisela ekhiqizwa ama-athomu amabili e-hydrogen kuma-molecule e-methane, kanye ne-CH2CL2 yama-molecule. I-Methylene Chloride ayinambala, icacile, inzima, futhi ishintshashintshayo. Inephunga nobumnandi obufana ne-ether. Ayishi. I-Methylene Chloride incibilika kancane emanzini, futhi incibilika nezinyibilikisi ezisetshenziswa kakhulu eziphilayo. Ingancibilika nganoma iyiphi indlela nezinye izinyibilikisi eziqukethe i-chlorine, i-ether, i-ethanol, kanye ne-N-di metamimamamide. I-Methylene Chloride kunzima ukuyincibilika ku-ammonia ewuketshezi ekushiseni kwegumbi, engancibilika ngokushesha ku-phenol, aldehyde, ketone, triathrin, tororine, cycamine, acetylcetate. I-phase Chemicalbook ingu-1.3266 (20/4 ° C). Iphuzu lokuncibilika -95.1 ° C. Iphuzu lokubila 40 ° C. Izinyibilikisi eziphansi ngokuphelele eziphansi zivame ukusetshenziselwa ukufaka esikhundleni se-petroleum ether evuthayo, i-ether, njll., futhi zingasetshenziswa njenge-anesthesia yendawo, i-refrigerant kanye ne-fire extinguishing agent. Iphuzu lokusha okuzenzakalelayo lingu-640 ° C. I-decoction (20 ° C) 0.43MPa · s. Inkomba yokubuyisa (20 ° C) 1.4244. Izinga lokushisa elibucayi lingu-237 ° C, kanti ingcindezi ebucayi ingu-6.0795MPa. I-HCL kanye neminonjana yokukhanya kukhiqizwa ngemuva kwesisombululo sokushisa, bese amanzi ashiswa isikhathi eside ukuze akhiqize i-formaldehyde kanye ne-HCL. I-chloride eyengeziwe, i-CHCL3 kanye ne-CCL4 ingatholakala.

Incazelo

Izakhiwo: I-dichloromethane emsulwa ayinayo i-flash point, futhi ingxube ye-solvent equkethe ivolumu elinganayo ye-dichloromethane nephethiloli, i-solvent naphtha noma i-toluene ayishisi. Kodwa-ke, uma i-dichloromethane ixutshwa ne-acetone noma i-methanol Chemicalbook liquid ekuxubeni kwesilinganiso esingu-10: 1, ingxube ine-flash point, umusi nomoya ukwakha ingxube eqhumayo, umkhawulo wokuqhuma ungu-6.2% ~ 15.0% (ivolumu).

Ukusetshenziswa kwe-Methylene Chloride

I-Methylene Chloride (DCM) inezinzuzo zokuncibilika okunamandla kanye nobuthi obuphansi. Isetshenziselwa ukukhiqiza ama-movie aphephile kanye ne-polycarbonate, kanti okunye kusetshenziswa njenge-solvent yokumboza, i-metal abandoning agent, i-gas smoke spray, i-polyurethane foaming agent, i-de-molding mold Damage, i-lacquer agent. I-Dichloromethane iwuketshezi olungenambala, olusetshenziswa njengendlela yokusabela embonini yezemithi ukulungiselela i-ammonia penicillin, i-hydroxycin kanye ne-pioneecin, njll.; Ama-organic synthetic extracting agents, i-polyurethane kanye nokunye ukukhiqizwa kwepulasitiki ye-foam kwama-foam agents kanye nama-medium cleaning agents. I-Dichloromethane isetshenziswa kakhulu emkhakheni wokukhiqizwa kwamafilimu kanye nemithi eShayina. Phakathi kwazo, ukusetshenziswa kokukhiqizwa kwamafilimu kubala u-50% wokusetshenziswa okuphelele, imithi ibala u-20% wokusetshenziswa okuphelele, ukusetshenziswa kwe-cleaner agent kanye nemboni yamakhemikhali kubala u-20% wokusetshenziswa okuphelele, kanti ezinye izici zibala u-10%. I-Dichloromethane isetshenziswa nasezinhlelweni zokuqandisa zezimboni ze-refrigerant, kodwa iyingozi kakhulu futhi ingakhiqiza ukukhanya okunobuthi lapho ithinta umlilo omncane noma izinto ezivuthayo. Uma kunomoya omanzi, i-hydrogen chloride e-hydrolyzed ingasetshenziswa ukukhuthaza i-hydrogen chloride, kanti ukukhanya kungakhuthaza i-hydrolysis futhi kuthuthukise insimbi ebolile. Isetshenziselwa ukupholisa i-grain fumigation kanye namadivayisi aqandisiwe aphansi kanye ne-air conditioner. Ekukhiqizweni kwepulasitiki ye-alkane yomchamo yohlobo lwe-polyether, isetshenziswa njenge-ejenti yokusiza ye-foam, kanye ne-ejenti ye-foam yokucindezela amapulasitiki e-polymutra foam. I-Dichloromethane isetshenziselwa nokwenza izinto zekhofi eyomile. Ikhofi iqala ipheke ukuze incibilikise i-caffeine bese intanta phezu kwayo, bese isebenzisa i-dichloromethane ukususa i-caffeine.
1. Kuyisithako esingashisi esinamachashazi aphansi abilayo, esisetshenziswa njenge-acetate cellulose membrane, esincibilika emoyeni futhi esilwa namagciwane, kanye nezithako ekukhiqizeni amavithamini.
2. I-Digerine iyinto eluhlaza ekhiqizwa yi-sterilizers i-azoxazole ne-mimozole, futhi iyisinyibilikisi esihle.
3. Ngaphezu kokwenziwa kwezinto zokwenziwa eziphilayo, lo mkhiqizo usetshenziswa kabanzi njenge-acetate cellulose membrane, i-triax cellulose pump, i-petroleum dehydration, i-gas solids kanye nama-antibiotic, amavithamini, ama-ethnic compounds, kanye ne-metal surfaces, kanye ne-metal surfaces Amakilasi Hlola i-CHEMICALBOOK ku-elux kanye ne-decapyles. Ngaphezu kwalokho, isetshenziselwa futhi amadivayisi abandayo nabandayo kanye nama-air conditioner aphansi. Ekukhiqizweni kwe-polyether -type urinary alkane plastic, isetshenziswa njenge-ejenti yokusiza ye-foam, kanye ne-ejenti ye-foam yokucindezela i-polychida foam plastics.
4. Khipha i-solvent. Uma isetshenziselwa ukukhipha i-caffeine kubhontshisi wekhofi. Iphinde isetshenziswe njengesinyibilikisi sezintaba, i-resin yamafutha anephunga elimnandi, njll. I-ejenti exutshwe yi-Pigyl.
5. Njenge-solvent, isetshenziselwa futhi ukwenziwa kwezinto eziphilayo.
6. Isinyibilikisi semboni ye-resin nepulasitiki. Sisetshenziswa kabanzi ezimbonini ezifana nezokwelapha, ipulasitiki kanye nefilimu.
7. Isinyibilikisi se-ethyl cellulose. I-ejenti yokukhipha amafutha namafutha. I-ether ethatha indawo ye-ether ne-petroleum ether.
