ʻO Dichloromethane (DCM; Methylene Chloride) (CAS: 75-09-2) he mea akaka, waihoʻoluʻu, mea hoʻoheheʻe halogenated aliphatic hydrocarbon pūhui me kahi etera-like ʻala ʻono.Hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka ethanol a me ka etera, a he mea hoʻoheheʻe haʻahaʻa haʻahaʻa hiki ʻole ke puhi ʻia ma lalo o nā kūlana hoʻohana maʻamau.I ka lilo ʻana o kona mahu i ka ʻike kiʻekiʻe i ka ea wela wela, e hoʻopuka ʻo ia i kahi kinoea hui pū ʻia, i hoʻohana pinepine ʻia e hoʻololi i ka flammable petroleum ether, ether, etc.
Dichloromethane (DCM; Methylene Chloride) (CAS: 75-09-2),Hoʻohana ʻia ma ke ʻano he waena i ka synthesis organik.Hoʻohana nui ʻia i nā lāʻau lapaʻau, a me nā mea hoʻonaninani, ka solvent kaʻina, ka pena, ka mea hoʻoheheʻe surfaces, extracting agent, uila ʻenekinia ʻoihana, plastics processing, a me nā ʻoihana ʻē aʻe.
Hoʻohana ʻia ʻo Dichloromethane ma ke ʻano paʻa paʻa i ka High Performance Liquid Chromatography a me Liquid Chromatography i hui pū ʻia me Mass Spectrometry.
Hoohana Paa Hale
Hoʻohana ʻia ka hui i ka hoʻoponopono hou ʻana i ka ʻauʻau.Hoʻohana nui ʻia ʻo Dichloromethane i ka ʻoihana i ka hana ʻana i nā lāʻau lapaʻau, nā mea huki, a me nā mea hoʻoheheʻe kaʻina.
ʻOihana a me nā mea hana hana
ʻO DCM kahi mea hoʻoheheʻe i loaʻa i loko o ka varnish a me nā mea huki pena, i hoʻohana pinepine ʻia e wehe i ka varnish a i ʻole ka pena pena mai nā ʻano like ʻole.Ma ke ʻano he solvent i ka ʻoihana lāʻau lapaʻau, hoʻohana ʻia ʻo DCM no ka hoʻomākaukau ʻana i ka cephalosporin a me ka ampicillin.
Hana Mea ʻai a me nā mea inu
Hoʻohana ʻia ia i ka hana ʻana i ka mea inu a me ka hana ʻana i ka meaʻai ma ke ʻano he mea hoʻoheheʻe.No ka laʻana, hiki ke hoʻohana ʻia ka DCM no ka hoʻopau ʻana i nā pīni kofe i kālua ʻole ʻia a me nā lau kī.Hoʻohana ʻia ka pūhui i ka hana ʻana i ka hops extract no ka pia, nā mea inu a me nā mea ʻono ʻē aʻe no nā meaʻai, a me ka hana ʻana i nā mea ʻala.
ʻOihana Kaʻahele
Hoʻohana mau ʻia ʻo DCM i ka hoʻoheheʻe ʻana i nā ʻāpana metala a me nā ʻili, e like me nā lako kaʻaahi a me nā alahele a me nā ʻāpana mokulele.Hiki ke hoʻohana ʻia i ka degreasing a me ka lubricating huahana i hoʻohana ʻia i nā huahana automotive, no ka laʻana, ka wehe ʻana i ka gasket a no ka hoʻomākaukau ʻana i nā ʻāpana metala no kahi gasket hou.
Hoʻohana maʻamau ka poʻe loea i nā kaʻa kaʻa kaʻa dichloromethane degreasing no ka wehe ʻana i ka momona a me nā aila mai nā ʻāpana kaʻa o ka transistor kaʻa, nā hui mokulele, nā ʻāpana mokulele, a me nā kaʻa diesel.I kēia lā, hiki i nā loea ke hoʻomaʻemaʻe a hoʻomaʻemaʻe wikiwiki i nā ʻōnaehana kaʻa me ka hoʻohana ʻana i nā ʻenehana degreasing e hilinaʻi ana i ka methylene chloride.
ʻOihana Lapaʻau
Hoʻohana ʻia ʻo Dichloromethane i loko o nā laboratories i ka unuhi ʻana i nā kemika mai nā meaʻai a i ʻole nā mea kanu no nā lāʻau lapaʻau e like me nā lāʻau antibiotic, steroids, a me nā huaora.Eia hou, hiki ke hoʻomaʻemaʻe maikaʻi a hoʻomaʻemaʻe koke i nā mea lapaʻau me ka hoʻohana ʻana i nā mea hoʻomaʻemaʻe dichloromethane me ka pale ʻana i ka pōʻino i nā ʻāpana wela a me nā pilikia corrosion.
Nā Kiʻiʻoniʻoni Kiʻi
Hoʻohana ʻia ka Methylene chloride ma ke ʻano he solvent i ka hana ʻana o cellulose triacetate (CTA), i hoʻohana ʻia i ka hana ʻana i nā kiʻiʻoniʻoni palekana i ke kiʻi.Ke hoʻoheheʻe ʻia i DCM, hoʻomaka ka CTA e evaporate ʻoiai ke waiho nei ka fiber o ka acetate ma hope.
ʻOihana uila
Hoʻohana ʻia ka methylene chloride i ka hana ʻana i nā papa kaapuni paʻi i ka ʻoihana uila.Hoʻohana ʻia ʻo DCM e hoʻomaʻemaʻe i ka ʻili pepa o ka substrate ma mua o ka hoʻohui ʻia ʻana o ka papa photoresist i ka papa.
ʻO ka Dichloromethane (DCM; Methylene Chloride) (CAS: 75-09-2) hoʻoneʻe ikaika i ke alo o nā metala honua alkali a i ʻole ka wai a e hoʻoheheʻe ʻia i formaldehyde i mua o kahi kumu wai.Loaʻa nā hopena alkylation ma nā hana ʻelua, no laila ka hopena di-substitutions.
Hoʻokaʻawale ʻia ʻo Dichloromethane (DCM; Methylene Chloride) (CAS: 75-09-2) ma ke ʻano he mea ʻawaʻawa wale nō e nā ala waha a me ka inhalation.Hiki ke alakaʻi i ka poʻo māmā, luhi, nāwaliwali, a me ka nausea ʻo ka ʻike ʻana i nā kiʻekiʻe o ka dichloromethane vapor (>500 ppm no 8 h).ʻO ka hoʻopili ʻana i ka pūhui me nā maka ke kumu i ka ʻeha ʻeha a hiki ke alakaʻi i ka conjunctivitis a me ka ʻeha ʻāʻī inā ʻaʻole wehe koke ʻia e ka holoi ʻana.'O ka dichloromethane he mea ho'onāwaliwali ma ka 'ili, a ma ka pili lō'ihi (e la'a, ma lalo o ka uhi o nā lole a i 'ole nā kāma'a) hiki ke hana i ke kuni ma hope o 30 a 60 mau minuke.ʻAʻole teratogenic ʻo Dichloromethane ma nā pae a hiki i 4500 ppm a i ʻole embryotoxic i nā ʻiole a me nā ʻiole ma nā pae a hiki i 1250 ppm.
ʻO nā pōʻino kūikawā o nā huahana kuni: ʻo nā huahana Dissociation i hana ʻia i ke ahi he mea hoʻonāukiuki a ʻona paha.
ʻAʻole kūpono me nā oxidizer ikaika, caustics;nā metala hana kemika, e like me ka aluminika, nā pauka magnesium;potassium, lithium, a me ka sodium;ʻAka nitric concentrated e hoʻopilikia i ke ahi a me ka pahū.Hoʻopili ʻia me nā wahi wela a i ʻole ke ahi e hoʻoheheʻe ʻia e hoʻohua ai i ka mahu o ka hydrogen chloride a me ke kinoea phosgene.Hoʻouka i kekahi mau ʻano o ka plastics, rubber and coatings.Hoʻouka i nā metala i mua o ka wai.
ʻO ka pale ʻana i ka hanu: ke ʻoi aku ka nui o ka ea ma mua o ka maʻamau, pono ʻoe e hoʻokomo i kahi mask kinoea pololei (half mask).E hoʻohana i ka respirator ea i ka wā o ka hoʻopakele pilikia a i ʻole ka haʻalele ʻana.Palekana maka: e hoʻohana i nā aniani palekana kemika inā pono.Palekana kino: e hoʻokomo i nā lole pale i ke komo ʻana o ka lāʻau make.Pale lima: e ʻaʻahu i nā mīkina lima kūpaʻa kemika.ʻO nā mea ʻē aʻe: pāpā ʻia ka puhi ʻana, ka ʻai ʻana a me ka inu ʻana ma ke kahua hana.Holoi a hoʻololi i nā lole ma hope o ka hana.E mālama kaʻawale i nā lole i hoʻohaumia ʻia a hoʻohana iā lākou no ke kū ma hope o ka holoi ʻana.E nānā pono i ka hoʻomaʻemaʻe pilikino.
