incazelo emfushane:

I-Methylene Chloride iyinhlanganisela ekhiqizwa ama-athomu amabili e-hydrogen kuma-athomu e-methane, kanye ne-molecular CH2CL2.I-Methylene Chloride ayinambala, i-transparent, inzima kakhulu, futhi iwuketshezi oluguquguqukayo.Inephunga nobumnandi obufana ne-ether.Ayishi.I-Methylene Chloride iyancibilika kancane emanzini, futhi incibilika ngezincibilikizi ezisetshenziswa kakhulu eziphilayo.Ingaphinda incibilike nganoma iyiphi ingxenye nezinye izinyibilikisi ezine-chlorine, i-ether, i-ethanol, ne-N-di metamimamamide.I-Methylene Chloride ilukhuni ukuncibilika ku-ammonia ewuketshezi ekamelweni lokushisa, elingaqedwa ngokushesha ku-phenol, aldehyde, ketone, methamphetamine, triathrin, tororine, cycamine, acetylcetate.Isigaba se-Chemicalbook singu-1.3266 (20/4 ° C).Iphuzu elincibilikayo -95.1 ° C. Iphuzu elibilayo lingu-40 ° C. Izincibilikisi zamaphuzu abilayo aphansi ngokugcwele zivame ukusetshenziselwa ukufaka i-ether ye-petroleum evuthayo, i-ether, njll., futhi ingasetshenziswa njenge-anesthesia yendawo, isiqandisi kanye ne-ejenti yokucisha umlilo.Indawo ezenzakalelayo yokuvutha ingu-640 ° C. I-decoction (20 ° C) 0.43MPa · s.Inkomba ye-refractive nd (20 ° C) 1.4244.Izinga lokushisa elibalulekile lingu-237 ° C, futhi ingcindezi ebucayi ingu-6.0795MPa.I-HCL kanye neminonjana yokukhanya kukhiqizwa ngemva kwesisombululo esishisayo, futhi amanzi ashiswa isikhathi eside ukuze akhiqize i-formaldehyde ne-HCL.I-chloride eyengeziwe, i-CHCL3 ne-CCL4 ingatholakala.

Incazelo

Izakhiwo: I-dichloromethane ehlanzekile ayinayo i-flash point, futhi ingxube ye-solvent equkethe umthamo olinganayo we-dichloromethane nophethiloli, i-solvent naphtha noma i-toluene ayikwazi ukuvutha.Nokho, lapho i-dichloromethane ixutshwa ne-acetone noma i-methanol Chemicalbook liquid ku-10: 1 proportion mixing, ingxube ine-flash point, umusi nomoya ukuze yakhe ingxube eqhumayo, umkhawulo wokuqhuma 6.2% ~ 15.0% (ivolumu).

Izicelo ze-Methylene Chloride

I-Methylene Chloride (DCM) inezinzuzo zokuncibilika okuqinile kanye nobuthi obuphansi.Isetshenziselwa ukukhiqiza amafilimu aphephile kanye ne-polycarbonate, kanti okunye kusetshenziswa njenge-solvent enamathelayo, i-ejenti yokulahla insimbi, isifutho sentuthu yegesi, i-polyurethane foaming agent, de -molding mold Umonakalo, i-lacquer agent.I-Dichloromethane iwuketshezi olungenambala, olusetshenziswa njengendlela yokusabela embonini yezemithi ukulungisa i-ammonia penicillin, i-hydroxycin ne-pioneecin, njll.;I-Organic synthetic extracting agents, i-polyurethane nokunye ukukhiqizwa kwepulasitiki eyigwebu kuma-ejenti agwebu kanye nama-ejenti okuhlanza insimbi.I-Dichloromethane isetshenziswa kakhulu emkhakheni wokukhiqiza amafilimu kanye nemithi e-China.Phakathi kwazo, ukusetshenziswa kokukhiqizwa kwefilimu kubala u-50% wengqikithi esetshenziswayo, i-akhawunti yemithi engu-20Chemicalbook% yayo yonke ukusetshenziswa, ukusetshenziswa kwe-ejenti yokuhlanza kanye nemboni yamakhemikhali kubala u-20% wengqikithi esetshenziswayo, kanye nezinye izici ze-akhawunti. ngo-10%.I-Dichloromethane iphinde isetshenziswe ezinhlelweni zeziqandisi zezimboni zesiqandisi, kodwa iyingozi kakhulu futhi ingakhiqiza ukukhanya okunobuthi lapho ithinta umlilo omncane noma izinto ezivuthayo.Endabeni yomoya oswakeme, i-hydrolyzed hydrogen chloride ingasetshenziswa ukuthuthukisa i-hydrogen chloride, futhi ukukhanya kungakhuthaza i-hydrolysis futhi kuthuthukise insimbi egqwalayo.Isetshenziselwa ukupholisa i-grain fumigation kanye ne-low-voltage eqandisiwe kanye nemishini yokupholisa umoya.Ekukhiqizeni ipulasitiki ye-polyether-type ye-urinary alkane, isetshenziswa njenge-ejenti eyisizayo yokugwedla, kanye nama-ejenti agwebu ukukhama amapulasitiki e-polymutra foam.I-Dichloromethane nayo isetshenziselwa ukwenza izinto zekhofi eliphelelwe amanzi emzimbeni.Ikhofi liqale liphekwe ukuze lincibilikise i-caffeine futhi lintante phezulu, bese lisebenzisa i-dichloromethane ukususa i-caffeine.
1. Kuyi-solvent yamachashazi angashi angashi, esetshenziswa njenge-acetate cellulose membrane, i-air-soluble kanye ne-antibacterial, kanye nezincibilikisi ekukhiqizeni amavithamini.
2. I-Digerine iwuketshezi olukhiqizwa ama-sterilizer azoxazole ne-mimozole, futhi iyincibilikisi enhle.
3. Ngaphezu kokwenziwa kwe-organic synthetic, lo mkhiqizo ubuye usetshenziswe kabanzi njengolwelwesi lwe-acetate cellulose, iphampu ye-triax cellulose, ukuphelelwa amandla kwamanzi kaphethiloli, izinto eziqinile zegesi nama-antibiotics, amavithamini, inhlanganisela yezinhlanga, nezindawo zensimbi, kanye nezindawo zensimbi Amakilasi Hlola I-CHEMICALBOOK ukuze i-elux ne-decapyles.Ngaphezu kwalokho, iphinde isetshenziselwe abandayo futhi low -voltage eqandisiwe kanye air -conditioning amadivaysi.Ekukhiqizeni ipulasitiki ye-polyether -uhlobo lwe-alkane yomchamo, isetshenziswa njenge-ejenti esizayo yokukhipha amagwebu, kanye nama-ejenti akhipha amagwebu okucindezela amapulasitiki egwebu le-polychida.
4. Khipha i-solvent.Uma isetshenziselwa ukukhipha i-caffeine kubhontshisi wekhofi.Ibuye isetshenziswe njenge-solvent yamagquma, i-resin yamafutha ephunga elimnandi, njll. I-agent ehlanjululwe ye-Pigyl.
5. I-solvent, iphinde isetshenziselwe ukuhlanganiswa kwezinto eziphilayo.
6. I-solvent ye-resin kanye nemboni yepulasitiki.Isetshenziswa kabanzi ezimbonini ezifana nemithi, amapulasitiki kanye nefilimu.
7. I-Ethyl cellulose solvent.I-ejenti yokukhipha amafutha namafutha.Ifaka esikhundleni se-ether ne-petroleum ether.
