Ka mānoanoa o dichloromethane: He nānā hohonu i kēia waiwai kino kī
ʻO ka Methylene chloride (kemimi: CH₂Cl₂), ʻike ʻia hoʻi ʻo chloromethane, he wai ʻala ʻono ʻole i hoʻohana nui ʻia i ka ʻoihana kemika, ʻoi aku ma ke ʻano he solvent. He mea nui ka hoʻomaopopo ʻana i ka waiwai kino o ka methylene chloride no kāna hoʻohana ʻana i ka ʻoihana. Ma kēia ʻatikala, e ʻimi mākou i nā mea kikoʻī o ka methylene chloride i ka kikoʻī a pehea ka hopena o kēia waiwai i kona hoʻohana ʻana i nā kaʻina kemika.
He aha ka nui o ka methylene chloride?
ʻO ka Density ka lakio o ka nuipaʻa o kahi mea i kona leo a he ʻāpana kino koʻikoʻi no ke ʻano o ka mea. ʻO ka nui o ka methylene chloride ma kahi o 1.33 g/cm³ (ma 20°C). Hōʻike kēia ʻano waiwai nui i ka methylene chloride ma mua o ka wai (1 g/cm³) ma ka mahana like, ʻo ia hoʻi, ʻoi aku ke kaumaha ma mua o ka wai. ʻO kēia waiwai paʻa e hiki ai i ka methylene chloride ke hōʻike i ke ʻano kūʻokoʻa i nā noi he nui, no ka laʻana i nā kaʻina hoʻokaʻawale wai-wai, kahi e kū mau ai ma lalo o ka papa wai.
Ka hopena o ka wela ma ka paʻa o ka methylene chloride
ʻOkoʻa ka nui o ka methylene chloride me ka mahana. ʻO ka maʻamau, e emi ana ka nui o ka methylene chloride i ka piʻi ʻana o ka mahana. ʻO kēia ma muli o ka hoʻonui ʻia ʻana o nā molekala ma muli o ke kiʻekiʻe o nā mahana, e hōʻemi ana i ka nui o ka maʻiʻo i kēlā me kēia leo. No ka laʻana, ma nā mahana kiʻekiʻe, hiki ke hāʻule ka nui o ka methylene chloride ma lalo o 1.30 g/cm³. He mea koʻikoʻi kēia hoʻololi no nā kaʻina hana kemika kahi e koi ʻia ai ka mana pololei o nā waiwai solvent, e like me ke kaʻina hana unuhi a hoʻokaʻawale paha, kahi e hoʻololi nui ai nā loli liʻiliʻi i nā hopena o ka hana. No laila, pono e noʻonoʻo pono ʻia ka hilinaʻi o ka wela ma ka hoʻolālā ʻana o nā kaʻina hana e pili ana i ka methylene chloride.
Ka hopena o ka dichloromethane density ma kāna mau noi
He hopena pololei ko Dichloromethane density i kāna mau noi he nui i ka ʻoihana. Ma muli o kona kiʻekiʻe kiʻekiʻe, ʻo dichloromethane kahi mea hoʻoheheʻe maikaʻi i ka ʻili wai-wai a kūpono loa no ka hoʻokaʻawale ʻana o nā pūhui kūlohelohe i hiki ʻole ke hui pū me ka wai. He mea hoʻoheheʻe maikaʻi loa ia i ka hana ʻana i nā pena, nā lāʻau lapaʻau, a me nā huahana kemika. ʻO ka nui o ka methylene chloride e hōʻike ana i nā waiwai kūʻokoʻa e pili ana i ka solubility kinoea a me ke kaomi mahu, a hoʻohana nui ʻia i nā mea hoʻohua, nā mea pena pena a me nā noi ʻē aʻe.
Hōʻuluʻulu manaʻo
He mea koʻikoʻi ka waiwai kino o ka dichloromethane density i ka ʻoihana kemika. ʻO ka hoʻomaopopo ʻana a me ka ʻike o kēia ʻāpana ʻaʻole kōkua wale i ka hoʻomaikaʻi ʻana i nā hana ʻoihana akā e hōʻoiaʻiʻo nō hoʻi i ka loaʻa ʻana o nā hopena maikaʻi loa o ke kaʻina hana ma nā kūlana wela like ʻole. Ma o ka nānā ʻana i kēia pepa, manaʻoʻiʻo e hiki i ka mea heluhelu ke loaʻa ka ʻike hohonu i ka nui o ka dichloromethane a me kona koʻikoʻi i nā noi ʻoihana.
