Dichloromethane (DCM; Methylene Chloride) (CAS: 75-09-2) ndi yowoneka bwino, yopanda mtundu, yosasinthika ya halogenated aliphatic hydrocarbon pawiri yokhala ndi fungo lokoma ngati ether.Amasungunuka pang'ono m'madzi, amasungunuka mu ethanol ndi ether, ndipo ndi chosungunulira chosayaka chotentha chotsika pansi pamikhalidwe yogwiritsidwa ntchito bwino.Pamene nthunzi yake imakhala yochuluka kwambiri mu mpweya wotentha kwambiri, imapanga mpweya wosakanikirana woyaka, womwe nthawi zambiri umagwiritsidwa ntchito m'malo mwa Flammable petroleum ether, ether, etc.
Dichloromethane (DCM; Methylene Chloride) (CAS: 75-09-2),Amagwiritsidwa ntchito ngati wapakatikati mu organic synthesis.Amagwiritsidwa ntchito kwambiri mu mankhwala, ndi zodzoladzola, ndondomeko zosungunulira, utoto, pamwamba degreasing wothandizira, wopezera wothandizira, makampani magetsi zomangamanga, mapulasitiki processing, ndi mafakitale ena.
Dichloromethane imagwiritsidwa ntchito ngati gawo la mafoni mu High Performance Liquid Chromatography ndi Liquid Chromatography yophatikizidwa ndi Mass Spectrometry.
Kugwiritsa Ntchito Nyumba
Pagululi amagwiritsidwa ntchito pokonzanso bafa.Dichloromethane imagwiritsidwa ntchito kwambiri m'mafakitale popanga mankhwala, ma strippers, ndi ma solvents.
Ntchito Zamakampani ndi Zopanga
DCM ndi chosungunulira chomwe chimapezeka mu vanishi ndi zopaka utoto, zomwe nthawi zambiri zimagwiritsidwa ntchito pochotsa ma varnish kapena zokutira zopaka utoto kuchokera kumalo osiyanasiyana.Monga zosungunulira mu makampani opanga mankhwala, DCM ntchito yokonza cephalosporin ndi ampicillin.
Kupanga Chakudya ndi Chakumwa
Amagwiritsidwanso ntchito popanga zakumwa ndi zakudya ngati zosungunulira.Mwachitsanzo, DCM ikhoza kugwiritsidwa ntchito kuchotsera caffeine nyemba za khofi zosakazinga komanso masamba a tiyi.Mankhwalawa amagwiritsidwanso ntchito popanga ma hops amowa, zakumwa ndi zokometsera zina zazakudya, komanso pokonza zonunkhira.
Makampani Oyendera
DCM nthawi zambiri imagwiritsidwa ntchito pochotsa zitsulo ndi malo, monga zida za njanji ndi njanji komanso zida zandege.Itha kugwiritsidwanso ntchito pochotsa mafuta ndi kudzoza zinthu zomwe zimagwiritsidwa ntchito pamagalimoto, mwachitsanzo, kuchotsa gasket ndikukonzekera zida zachitsulo za gasket yatsopano.
Akatswiri amagalimoto nthawi zambiri amagwiritsa ntchito vapor dichloromethane degreasing pochotsa mafuta ndi mafuta m'magawo agalimoto a transistor yamagalimoto, ma ndege am'mlengalenga, zida zandege, ndi ma mota a dizilo.Masiku ano, akatswiri amatha kuyeretsa mwachangu komanso mwachangu njira zoyendera pogwiritsa ntchito njira zochepetsera zomwe zimadalira methylene chloride.
Makampani azachipatala
Dichloromethane amagwiritsidwa ntchito m'ma laboratories pochotsa mankhwala kuchokera ku zakudya kapena zomera ku mankhwala monga maantibayotiki, steroids, ndi mavitamini.Kuphatikiza apo, zida zamankhwala zimatha kutsukidwa bwino komanso mwachangu pogwiritsa ntchito zotsuka za dichloromethane ndikupewa kuwonongeka kwa magawo osamva kutentha komanso zovuta za dzimbiri.
Mafilimu Ojambula
Methylene chloride imagwiritsidwa ntchito ngati chosungunulira popanga cellulose triacetate (CTA), yomwe imagwiritsidwa ntchito popanga mafilimu oteteza zithunzi.Ikasungunuka mu DCM, CTA imayamba kusanduka nthunzi pamene ulusi wa acetate umakhala kumbuyo.
Makampani Amagetsi
Methylene chloride imagwiritsidwa ntchito popanga matabwa osindikizidwa mumakampani amagetsi.DCM imagwiritsidwa ntchito kutsitsa zojambulazo pamwamba pa gawo lapansi gawo la photoresist lisanawonjezedwe pa bolodi.
Dichloromethane (DCM; Methylene Chloride) (CAS: 75-09-2) imachita mwamphamvu pamaso pa zitsulo zamchere zamchere kapena zamchere zamchere ndipo imasungunuka kukhala formaldehyde pamaso pa madzi amadzimadzi.Zochita za alkylation zimachitika pazigawo zonse ziwiri, motero zimasintha.
Dichloromethane (DCM; Methylene Chloride) (CAS: 75-09-2) imadziwika kuti ndi poizoni pang'ono chabe ndi njira zapakamwa ndi zopumira.Kukumana ndi mpweya wochuluka wa dichloromethane (>500 ppm kwa 8 h) kungayambitse mutu, kutopa, kufooka, ndi nseru.Kukhudzana ndi maso kumayambitsa kupsa mtima kowawa ndipo kungayambitse conjunctivitis ndi kuvulala kwa cornea ngati sikuchotsedwa mwamsanga ndi kuchapa.Dichloromethane ndi yomwe imakwiyitsa khungu pang'ono, ndipo ikakhudza nthawi yayitali (mwachitsanzo, pansi pa chophimba cha zovala kapena nsapato) imatha kuyambitsa kuyaka pambuyo pa 30 mpaka 60 min.Dichloromethane si teratogenic pamilingo mpaka 4500 ppm kapena embryotoxic mu makoswe ndi mbewa pamilingo mpaka 1250 ppm.
Zowopsa Zapadera Zazinthu Zoyaka: Zinthu zolekanitsa zomwe zimapangidwa pamoto zitha kukhala zokwiyitsa kapena zowopsa.
Zosagwirizana ndi oxidizer amphamvu, caustics;zitsulo zogwira ntchito, monga aluminiyamu, ufa wa magnesium;potaziyamu, lithiamu, ndi sodium;nitric acid wokhazikika kuchititsa ngozi ya moto ndi kuphulika.Kukhudzana ndi malo otentha kapena malawi amoto kumayambitsa kuwola kumatulutsa utsi wa hydrogen chloride ndi mpweya wa phosgene.Imaukira mitundu ina ya mapulasitiki, mphira ndi zokutira.Kuukira zitsulo pamaso pa chinyezi.
Chitetezo chopumira: pamene ndende ya mpweya idutsa muyeso, muyenera kuvala chigoba chachindunji cha gasi (theka chigoba).Valani chopumira mpweya panthawi yopulumutsa mwadzidzidzi kapena potuluka.Chitetezo m'maso: valani magalasi oteteza mankhwala pakafunika kutero.Kuteteza thupi: Valani zovala zodzitchinjiriza kuti musalowemo poizoni.Chitetezo m'manja: Valani magolovesi osamva mankhwala.Ena: kusuta, kudya ndi kumwa ndizoletsedwa kuntchito.Sambani ndikusintha zovala mukamaliza ntchito.Sungani zovala zoipitsidwa padera ndikuzigwiritsira ntchito poyimirira mukachapa.Samalani ndi ukhondo waumwini.
