I-Dichloromethane (DCM; I-Methylene Chloride) (i-CAS: 75-09-2) iyinhlanganisela ye-halogenated aliphatic aliphatic hydrocarbon esobala, engenambala, enephunga elimnandi elinjenge-ether.Incibilika kancane emanzini, inyibilika ku-ethanol ne-ether, futhi iyisincibilikisi esibilayo esingashi ngaphansi kwezimo ezivamile zokusetshenziswa.Uma umhwamuko wawo uba phezulu emoyeni onezinga lokushisa eliphezulu, uzokhiqiza igesi exubene evutha kalula, evame ukusetshenziselwa ukufaka esikhundleni se-Flammable petroleum ether, ether, njll.
I-Dichloromethane (DCM; I-Methylene Chloride) (CAS: 75-09-2),Isetshenziswa njengendawo emaphakathi ku-organic synthesis.Isetshenziswa kakhulu kwezemithi, nezimonyo, i-solvent, upende, i-ejenti yokwehlisa amafutha, i-ejenti ekhiphayo, imboni yobunjiniyela bakagesi, ukucubungula amapulasitiki, nezinye izimboni.
I-Dichloromethane isetshenziswa njengesigaba seselula ku-High Performance Liquid Chromatography kanye ne-Liquid Chromatography ehlanganiswe ne-Mass Spectrometry.
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.
I-Dichloromethane (DCM; I-Methylene Chloride) (CAS: 75-09-2) isabela ngobudlova phambi kwe-alkali noma izinsimbi zomhlaba ezine-alkaline futhi izokhipha i-hydrolyze ibe i-formaldehyde phambi kwesisekelo esimanzi.Ukusabela kwe-alkylation kwenzeka kuyo yomibili imisebenzi, ngaleyo ndlela umphumela wokushintshaniswa kwe-di-substitution.
I-Dichloromethane (DCM; I-Methylene Chloride) (CAS: 75-09-2) ihlukaniswa njengenobuthi obuncane ngemizila yomlomo neyokuhogela.Ukuchayeka ekugxilweni okuphezulu komhwamuko we-dichloromethane (>500 ppm amahora angu-8) kungaholela ekubeni nekhanda elilula, ukukhathala, ubuthakathaka, nesicanucanu.Ukuthintana kwenhlanganisela ngamehlo kubangela ukucasuka okubuhlungu futhi kungaholela ekujuleni kobuchopho kanye nokulimala kwekhone uma kungasuswa ngokushesha ngokuwashwa.I-Dichloromethane iwukucasula isikhumba esithambile, futhi lapho uthintana isikhathi eside (isb, ngaphansi kwesembozo sezingubo noma izicathulo) ingabangela ukusha ngemva kokuchayeka emaminithini angu-30 kuya kwangu-60.I-Dichloromethane ayiyona i-teratogenic kumazinga afika ku-4500 ppm noma i-embryotoxic kumagundane namagundane kumazinga afika ku-1250 ppm.
Izingozi Ezikhethekile Zemikhiqizo Evuthayo: Imikhiqizo yokuhlukanisa ekhiqizwe emlilweni ingase icasule noma ibe nobuthi.
Akuhambisani nama-oxidizers aqinile, ama-caustics;izinsimbi ezisebenza ngamakhemikhali, njenge-aluminium, i-magnesium powders;i-potassium, i-lithium ne-sodium;i-nitric acid egxilile edala ingozi yomlilo nokuqhuma.Ukuthintana nezindawo ezishisayo noma amalangabi kubangela ukubola kukhiqiza intuthu ye-hydrogen chloride negesi ye-phosgene.Ihlasela ezinye izinhlobo zamapulasitiki, irabha kanye nama-coatings.Ihlasela izinsimbi lapho kukhona umswakama.
Ukuvikelwa kokuphefumula: lapho ukugxila emoyeni kudlula izinga, kufanele ugqoke imaski yegesi eqondile (i-half mask).Gqoka isishicileli somoya ngesikhathi sokuhlenga isimo esiphuthumayo noma uphuma.Ukuvikela iso: gqoka izibuko zokuphepha zamakhemikhali uma kunesidingo.Ukuvikela umzimba: Gqoka izingubo ezivikelayo ekungeneni koshevu.Ukuvikela isandla: gqoka amagilavu amelana namakhemikhali.Abanye: ukubhema, ukudla nokuphuza akuvunyelwe endaweni yokusebenza.Shawa futhi ushintshe izingubo ngemva komsebenzi.Gcina izingubo ezingcolile ngokuhlukana futhi uzisebenzise kokulinda ngemva kokuwashwa.Naka inhlanzeko yomuntu siqu.
I-UN1593 Dichloromethane, Ikilasi Lengozi: 6.1;Amalebula: 6.1-Izinto ezinobuthi.
