Mea Hana Kumukūʻai Maikaʻi Methylene Chloride CAS: 75-09-2

wehewehe pōkole:

ʻO Methylene Chloride kahi hui i hana ʻia e ʻelua mau ʻātoma hydrogen i loko o nā molekala methane, a me ka molekala CH2CL2. ʻO ka Methylene Chloride he wai ʻole ke kala, moakaka, kaumaha, a me ka hū. Loaʻa iā ia kahi ʻala a me ka ʻono e like me ka ether. ʻAʻole ia e puhi. He mea hoʻoheheʻe iki ka Methylene Chloride i ka wai, a hoʻoheheʻe ʻia me nā mea hoʻoheheʻe organik i hoʻohana pinepine ʻia. Hiki ke hoʻoheheʻe ʻia i kekahi ʻano me nā mea hoʻoheheʻe chlorine ʻē aʻe, ether, ethanol, a me N-di metamimamamide. He paʻakikī ke hoʻoheheʻe ʻia ka Methylene Chloride i loko o ka ammonia wai ma ka mahana o ka lumi, hiki ke hoʻoheheʻe koke ʻia i loko o ka phenol, aldehyde, ketone, triathrin, tororine, cycamine, acetylcetate. ʻO ka pae Chemicalbook he 1.3266 (20/4 ° C). ʻO ke kiko hoʻoheheʻe -95.1 ° C. ʻO ke kiko paila 40 ° C. Hoʻohana pinepine ʻia nā mea hoʻoheheʻe kiko paila haʻahaʻa piha e pani i ka petroleum ether flammable, ether, a pēlā aku, a hiki ke hoʻohana ʻia ma ke ʻano he anesthesia kūloko, refrigerant a me ka mea kinai ahi. ʻO ke kiko puhi kūlohelohe he 640 ° C. ʻO ka decoction (20 ° C) 0.43MPa · s. ʻO ka index refractive nd (20 ° C) 1.4244. ʻO ka mahana koʻikoʻi he 237 ° C, a ʻo ke kaomi koʻikoʻi he 6.0795MPa. Hoʻopuka ʻia ka HCL a me nā koena o ke kukui ma hope o ka hoʻonā wela, a hoʻomehana ʻia ka wai no ka manawa lōʻihi e hana i ka formaldehyde a me HCL. Hiki ke loaʻa hou ka chloride, CHCL3 a me CCL4.

Nā Waiwai: ʻAʻohe kiko lapalapa o ka dichloromethane maʻemaʻe, a ʻaʻole hiki ke lapalapa kahi hui solvent e loaʻa ana ka nui like o ka dichloromethane a me ka gasoline, ka solvent naphtha a i ʻole toluene. Eia nō naʻe, i ka wā e hui pū ʻia ai ka dichloromethane me ka acetone a i ʻole ka methanol wai ma ka hui ʻana o 10: 1, loaʻa i ka hui kahi kiko lapalapa, ka mahu a me ka ea e hana i kahi hui pahū, ka palena pahū 6.2% ~ 15.0% (nui).

Nā noi o Methylene Chloride

Loaʻa i ka Methylene Chloride (DCM) nā pono o ka solubility ikaika a me ka haʻahaʻa toxicity. Hoʻohana ʻia ia no ka hana ʻana i nā kiʻiʻoniʻoni palekana a me ka polycarbonate, a hoʻohana ʻia ke koena ma ke ʻano he solvent coating, metal abandoning agent, gas smoke spray, polyurethane foaming agent, de -molding mold Damage, lacquer agent. He wai kala ʻole ʻo Dichloromethane, i hoʻohana ʻia ma ke ʻano he medium reaction ma ka ʻoihana lāʻau lapaʻau e hoʻomākaukau i ka ammonia penicillin, hydroxycin a me pioneecin, etc.; ʻO nā mea hoʻokaʻawale synthetic organik, polyurethane a me nā hana plastik foam ʻē aʻe no nā mea hoʻopū a me nā mea hoʻomaʻemaʻe metala. Hoʻohana nui ʻia ʻo Dichloromethane ma ke kahua o ka hana kiʻiʻoniʻoni a me nā lāʻau lapaʻau ma Kina. I waena o lākou, ʻo ka hoʻohana ʻana i ka hana kiʻiʻoniʻoni he 50% o ka hoʻohana holoʻokoʻa, ʻo ka lāʻau lapaʻau he 20% o ka hoʻohana holoʻokoʻa, ʻo ka hoʻohana ʻana i ka mea hoʻomaʻemaʻe a me ka ʻoihana kemika he 20% o ka hoʻohana holoʻokoʻa, a ʻo nā ʻano ʻē aʻe he 10%. Hoʻohana ʻia ʻo Dichloromethane i nā ʻōnaehana refrigerant ʻoihana no ka refrigerant, akā he mea ʻino loa ia a hiki ke hana i ka mālamalama ʻawahia i ka wā e hoʻopili ai i ke ahi māmā a i ʻole nā mea e ʻā ana. I ke ʻano o ka ea pulu, hiki ke hoʻohana ʻia ka hydrogen chloride hydrolyzed e hoʻolaha i ka hydrogen chloride, a hiki i ka mālamalama ke hoʻolaha i ka hydrolysis a hoʻonui i ka metala ʻino. Hoʻohana ʻia no ka hoʻomaʻalili ʻana o ka fumigation palaoa a me nā mea hoʻoluʻu haʻahaʻa-voltage a me nā mea hoʻoluʻu ea. I ka hana ʻana o ka plastic alkane urinary polyether, hoʻohana ʻia ia ma ke ʻano he mea hoʻopūpī kōkua, a me nā mea hoʻopūpī no ka ʻomi ʻana i nā plastics foam polymutra. Hoʻohana ʻia hoʻi ʻo Dichloromethane e hana i nā mea no ke kofe dehydrated. Hoʻomoʻa mua ke kofe e hoʻoheheʻe i ka caffeine a lana ma luna o ka ʻili, a laila hoʻohana i ka dichloromethane e wehe i ka caffeine.
1. He mea hoʻoheheʻe kiko paila haʻahaʻa ʻaʻole hiki ke puhi ʻia, kahi i hoʻohana ʻia e like me ka membrane cellulose acetate, hiki ke hoʻoheheʻe ʻia i ka ea a me ka antibacterial, a me nā mea hoʻoheheʻe i ka hana ʻana i nā huaora.
2. He mea maka ʻo Digerine i hana ʻia e nā sterilizers azoxazole a me mimozole, a he mea hoʻoheheʻe maikaʻi nō hoʻi ia.
3. Ma waho aʻe o ka synthesis synthetic organik, hoʻohana nui ʻia kēia huahana ma ke ʻano he membrane acetate cellulose, triax cellulose pump, petroleum dehydration, gas solids a me antibiotics, vitamins, 甾 ethnic compounds, a me nā ʻili metala, a me nā ʻili metala Classes Check CHEMICALBOOK i elux a me decapyles. Eia kekahi, hoʻohana ʻia no nā mea hoʻoluʻu anu a me ka haʻahaʻa-voltage hau a me nā mea hoʻoluʻu ea. I ka hana ʻana o ka polyether-type urinary alkane plastic, hoʻohana ʻia ia ma ke ʻano he mea hoʻohua kōkua, a me nā mea hoʻohua no ka ʻū ʻana i nā polychida foam plastics.
4. Mea hoʻoheheʻe unuhi. Inā hoʻohana ʻia e unuhi i ka caffeine i loko o nā pīni kope. Hoʻohana ʻia hoʻi ia ma ke ʻano he mea hoʻoheheʻe no nā puʻu, ka resin ʻaila ʻala, a me nā mea ʻē aʻe. ʻO ka mea hoʻoheheʻe Pigyl.
5. No ka mea hoʻoheheʻe, hoʻohana ʻia nō hoʻi no ka hana ʻana i nā mea olaola.
6. Mea hoʻoheheʻe no ka ʻoihana resin a me ka palakiko. Hoʻohana nui ʻia ia i nā ʻoihana e like me ka lāʻau lapaʻau, nā palakiko a me ke kiʻiʻoniʻoni.
7. Mea hoʻoheheʻe Ethyl cellulose. Mea hoʻokaʻawale momona a me ka ʻaila. He pani no ka ether a me ka petroleum ether.
