I-Dichloromethane (i-DCM; i-Methylene Chloride) (i-CAS: i-75-09-2) i-transparent, i-colorless, i-volatile halogenated aliphatic hydrocarbon ikhompawundi ene-ether-efana nephunga elimnandi elimnandi.Inyibilika kancinane emanzini, inyibilika kwi-ethanol kunye ne-ether, kwaye isinyibilikisi esingatshiyo esibilisa kancinci phantsi kweemeko eziqhelekileyo zokusetyenziswa.Xa umphunga wayo uba yingqwalasela ephezulu kumoya wobushushu obuphezulu, uya kuvelisa irhasi exubeneyo enokutsha ebuthathaka, ehlala isetyenziselwa ukutshintsha i-ether yepetroleum evuthayo, i-ether, njl.
I-Dichloromethane (DCM; i-Methylene Chloride) (i-CAS: 75-09-2),Isetyenziswa njengendawo ephakathi kwi-organic synthesis.Isetyenziswa kakhulu kumayeza, nakwizithambiso, kwi-solvent, ipeyinti, i-ejenti yokucoca indawo, iarhente yokukhupha, ishishini lobunjineli bombane, ukusetyenzwa kweeplastiki, kunye namanye amashishini.
IDichloromethane isetyenziswa njengesigaba esihambayo kwiHigh Performance Liquid Chromatography kunye neLiquid Chromatography edityaniswa neMass Spectrometry.
Ukusetyenziswa kweNdlu
Ikhompawundi isetyenziswa ekuhlaziyeni ibhafu.I-Dichloromethane isetyenziswa kakhulu kwimizi-mveliso kwimveliso yamayeza, ii-strippers, kunye nezinyibilikisi zenkqubo.
Usetyenziso lwezoShishino kunye neMveliso
I-DCM sisinyibilikisi esifumaneka kwi-varnish kunye ne-strippers yepeyinti, ehlala isetyenziselwa ukususa ivanishi okanye iipeyinti zepeyinti kwiindawo ezahlukeneyo.Njenge-solvent kwishishini lamachiza, i-DCM isetyenziselwa ukulungiswa kwe-cephalosporin kunye ne-ampicillin.
Ukwenziwa koKutya kunye neziselo
Iyasetyenziswa nasekuveliseni isiselo kunye nokwenziwa kokutya njengesinyibilikisi esikhuphayo.Umzekelo, i-DCM ingasetyenziselwa ukuthobisa iimbotyi zekofu ezingagcadwanga kunye namagqabi eti.Ikhompawundi ikwasetyenziswa ekudaleni ihops extract yebhiya, iziselo kunye nezinye iziqholo ekutyeni, nasekulungiseni izinongo.
Ishishini lezoThutho
I-DCM iqhele ukusetyenziselwa ukucolwa kwentsimbi kunye nemigangatho, njengezixhobo zikaloliwe kunye neengoma kunye nezinto zenqwelomoya.Isenokusetyenziswa ekudambiseni igrisi kunye neemveliso zokuthambisa ezisetyenziswa kwiimveliso zeemoto, umzekelo, ukususwa kwegasket kunye nokulungiselela iindawo zentsimbi zegasket entsha.
Iingcali kwiimoto zihlala zisebenzisa inkqubo yokunciphisa idichloromethane yomphunga ukuya ekususeni igrisi kunye neeoyile kwiindawo zemoto zetransistor yemoto, iindibano zesphekepheke, izinto zenqwelomoya, kunye neenjini zedizili.Namhlanje, iingcali ziyakwazi ukucoca ngokukhuselekileyo nangokukhawuleza iinkqubo zothutho zisebenzisa iindlela zokuthoba ezixhomekeke kwi-methylene chloride.
Ishishini lezonyango
I-Dichloromethane isetyenziswa kwiilabhoratri ekutsalweni kweekhemikhali ekutyeni okanye kwizityalo kumayeza afana ne-antibiotics, i-steroids, kunye neevithamini.Ukongeza, izixhobo zonyango zinokucocwa ngokufanelekileyo nangokukhawuleza kusetyenziswa izicoci ze-dichloromethane ngelixa zithintela umonakalo kwiindawo ezingeva lubushushu kunye neengxaki zokubola.
Iifilimu zeeFoto
I-Methylene chloride isetyenziswe njenge-solvent kwimveliso ye-cellulose triacetate (CTA), esetyenziswa ekudalweni kweefilimu ezikhuselekileyo kwiifoto.Xa inyibilika kwi-DCM, i-CTA iqala ukujika ibe ngumphunga njengoko i-fiber ye-acetate ihlala ngasemva.
Ishishini lombane
I-Methylene chloride isetyenziselwa ukuveliswa kweebhodi zeesekethe eziprintiweyo kwishishini lombane.I-DCM isetyenziselwa ukuthoba umphezulu wefoyile ye-substrate phambi kokuba umaleko wefotoresist wongezwe ebhodini.
I-Dichloromethane (i-DCM; i-Methylene Chloride) (i-CAS: 75-09-2) iphendula ngobudlova phambi kwe-alkali okanye i-alkaline yesinyithi yomhlaba kwaye iya ku-hydrolyze kwi-formaldehyde phambi kwesiseko samanzi.Ukusabela kwe-alkylation kwenzeka kuyo yomibini imisebenzi, ngoko ke i-di-substitution ibangela.
I-Dichloromethane (i-DCM; i-Methylene Chloride) (i-CAS: 75-09-2) ihlelwa njengetyhefu nje encinci ngeendlela zomlomo kunye ne-inhalation.Ukuba sesichengeni kuxinzelelo oluphezulu lomphunga we-dichloromethane (>500 ppm kwi-8 h) kunokukhokelela ekubeni ube nentloko ekhanyayo, ukudinwa, ubuthathaka, kunye nesicaphucaphu.Ukuqhagamshelana nekhompawundi ngamehlo kubangela ukucaphuka okubuhlungu kwaye kunokukhokelela kwi-conjunctivitis kunye nokulimala kwe-corneal ukuba ayisuswanga ngokukhawuleza ngokuhlamba.I-Dichloromethane yinto encinci ecaphukisa ulusu, kwaye xa udibana naye ixesha elide (umzekelo, phantsi kwengubo okanye izihlangu) kunokubangela ukutshisa emva kwe-30 ukuya kwi-60 min yokuvezwa.I-Dichloromethane ayikho i-teratogenic kumanqanaba ukuya kuma-4500 ppm okanye i-embryotoxic kwiimpuku kunye neempuku kumanqanaba ukuya kwi-1250 ppm.
Iingozi eziKhethekileyo zeeMveliso zokutsha: Iimveliso zokuqhawula eziveliswe emlilweni zinokucaphukisa okanye zinetyhefu.
Ukungahambelani ne-oxidizers eqinile, i-caustics;iintsimbi ezisebenza ngekhemikhali, ezifana ne-aluminium, i-magnesium powders;i-potassium, i-lithium kunye ne-sodium;i-nitric acid egxile kwi-nitric ebangela ingozi yomlilo kunye nokudubula.Ukudibana neendawo ezishushu okanye amadangatye kubangela ukubola kuvelisa imisi yehydrogen chloride kunye negesi yephosgene.Uhlasela ezinye iintlobo zeplastiki, irabha kunye neengubo.Uhlaselo lwesinyithi phambi kokufuma.
Ukukhuselwa kokuphefumula: xa ukugxininiswa emoyeni kudlula umgangatho, kufuneka ugqoke imaski yegesi ngqo (isiqingatha semaski).Nxiba isiphefumlo somoya ngexesha lokuhlangula okanye ukukhutshwa.Ukukhuselwa kwamehlo: nxiba iiglasi zokhuseleko lwekhemikhali xa kuyimfuneko.Ukhuseleko lomzimba: Nxiba impahla ekhuselayo ekungeneni kwityhefu.Ukukhuselwa kwesandla: nxiba iiglavu ezixhathisa iikhemikhali.Abanye: ukutshaya, ukutya nokusela akuvumelekanga kwindawo yokusebenza.Hlamba utshintshe iimpahla emva komsebenzi.Gcina iimpahla ezingcolisekileyo ngokwahlukeneyo kwaye uzisebenzise kwindawo yokulinda emva kokuhlanjwa.Nikela ingqalelo kucoceko lobuqu.
I-UN1593 Dichloromethane, iKlasi yeeNgozi: 6.1;Iileyibhile: 6.1-Izinto ezinetyhefu.
