Igama Lomkhiqizo:I-Dichloromethane

Ifomethi ye-Molecular:I-CH2Cl2

Inombolo ye-CAS:75-09-2

Isakhiwo samangqamuzana omkhiqizo:

Chemical Properties:

I-Dichloromethane, isakhi esiphilayo esinefomula yamakhemikhali i-CH2Cl2, iwuketshezi olungenambala olusobala olunephunga elicasulayo njenge-ether. Incibilika kancane emanzini, incibilika ku-ethanol ne-ether, iyisici esincibilikisayo esingashi esiphansi ngaphansi kwezimo ezivamile zokusetshenziswa, futhi umhwamuko wayo ugxila kakhulu emoyeni oshisa kakhulu ngaphambi kokukhiqiza ingxube yamagesi ekwazi ukusha, futhi ngokuvamile isetshenziswa. ukufaka esikhundleni se-petroleum ether evuthayo, i-ether, njll.

Isicelo:

Ukusetshenziswa Kwezindlu
Inhlanganisela isetshenziswa ekulungiseni ubhavu. I-Dichloromethane isetshenziswa kakhulu ezimbonini ekukhiqizeni imithi, ama-stripper, kanye nezincibilikisi zenqubo.
Ukusetshenziswa Kwezimboni Nezokukhiqiza
I-DCM iyi-solvent etholakala kuma-varnish nama-stripper opende, avame ukusetshenziselwa ukususa i-varnish noma i-peint coatings ezindaweni ezihlukahlukene. Njengento encibilikayo embonini yezemithi, i-DCM isetshenziselwa ukulungisa i-cephalosporin ne-ampicillin.
Ukukhiqiza Ukudla Neziphuzo
Ibuye isetshenziselwe ukukhiqiza isiphuzo kanye nokudla njenge-solvent yokukhipha. Isibonelo, i-DCM ingasetshenziselwa ukukhipha i-caffeine ubhontshisi wekhofi ongagazingiwe kanye namaqabunga etiye. I-compound iphinde isetshenziselwe ukwenza i-hops extract for ubhiya, iziphuzo nokunye ukunambitheka kokudla, kanye nokucubungula izinongo.
Imboni Yezokuthutha
I-DCM ivamise ukusetshenziselwa ukucoliswa kwezingxenye zensimbi nezindawo ezingaphezulu, njengamathuluzi kaloliwe namathrekhi kanye nezingxenye zendiza. Ingase futhi isetshenziselwe ukwehlisa amafutha kanye nemikhiqizo yokugcoba esetshenziswa emikhiqizweni yezimoto, isibonelo, ukukhishwa kwe-gasket kanye nokulungisa izingxenye zensimbi ze-gasket entsha.
Ochwepheshe bezimoto bavamise ukusebenzisa inqubo yokukhishwa kwe-vapor dichloromethane ukuze kukhishwe amafutha namafutha ezingxenyeni zemoto ze-transistor yemoto, imihlangano yemikhumbi-mkhathi, izingxenye zendiza, namamotho kadizili. Namuhla, ochwepheshe bayakwazi ukuhlanza ngokuphepha nangokushesha izinhlelo zokuhamba besebenzisa amasu okwehlisa amafutha ancike ku-methylene chloride.
Imboni Yezokwelapha
I-Dichloromethane isetshenziswa kulabhorethri lapho kukhishwa amakhemikhali ekudleni noma ezitshalweni zemithi enjengama-antibiotics, ama-steroids, namavithamini. Ngaphezu kwalokho, imishini yezokwelapha ingahlanzwa kahle futhi ngokushesha kusetshenziswa izihlanzi ze-dichloromethane kuyilapho igwema ukulimala ezingxenyeni ezingezwani nokushisa nezinkinga zokugqwala.
Amafilimu Ezithombe
I-Methylene chloride isetshenziswa njenge-solvent ekukhiqizeni i-cellulose triacetate (CTA), esetshenziswa ekudaleni amafilimu okuphepha ezithombeni. Uma incibilika ku-DCM, i-CTA iqala ukuhwamuka njengoba i-fiber ye-acetate isala ngemuva.
Imboni Yezogesi
I-Methylene chloride isetshenziswa ekukhiqizeni amabhodi wesifunda aphrintiwe embonini ye-elekthronikhi. I-DCM isetshenziselwa ukwehlisa amafutha engaphezulu kwe-substrate ngaphambi kokuthi ungqimba lwe-photoresist lwengezwe ebhodini.
