Formicʻakika

Formicʻakika (E 236, methanoicʻakika) nā monocarboxylic nāʻakika (paʻa kūhohonu loa) mea i loko o ka wahi mua. Ma lalo o maʻamau rula, o ka waiwai o ka colorless wai. Ke Nine Inch haʻilula o formicʻakika HCOOH.

Ma waho aʻeo i konaʻakika ano, e hōʻike i ka pono a me ka aldehydes. Keia mea aie a hiki i ka 'ole o ka E236 mea.

Na maoli ai 'ia waiwai i loaʻa i loko o paʻapū, paipu, hua, caustic a me ka nalo hopeʻeha secretions a me ka holo akula. Formicʻakika Ua ike mua, a i ho'ākāka 'ia i loko o ka 17th kenekulia. Ua aie kona inoa i ka waiwai, no ka mea, ka mea i loaʻa i loko o ka holo mālie.

Nō kāu, o ka ke keʻena ua hoʻohana 'ia me ka preservative a antibacterial Agena ma ka i ai. Nine waiwai o formicʻakika 'aʻole hoʻi i ka hoʻopöʻino' ia a me ka putrefaction. Ia mea ke kumu o ka silage a me ka mauʻu ia i keia waiwai, hoomau anei hou. Ka waiwai i hoʻohana ua ma ka laau lapaau. Ke dyeing hulu hipa (mordant) me Hekikai no ka ili tanning, ma ka mana o ka parasites ma apiculture like me ka'ūheheʻe iloko o kekahi o na reactions i pili formicʻakika.

Ke Nine Inch waiwai o ka waiwai i hōʻike like me ka hana o ka lehulehu. I kulike ai me ka eu Mea Maluna, ka laupaʻi haku mele 'ana o ka mai i ka 10% onovozdeystvuet annoyingly, oi ma mua o 10% - corrosive i.

100% formicʻakika (wai) ma ka hui 'ana me ka ili hoʻonāukiukiʻana mai o loa loa'ā. Kaniak i he uuku ka nui o ka mea i loko o ia i ka lehulehu ma o ka poi ke kumu nui eha. Ka hoʻohuli ai i nā 'āpana mua hoʻomaka e huli keʻokeʻo me ina uhi me ka hau laila, i like me ka mahuahua. A puni ka mea kuni i ka mea wahi ua hana ia e kekahi ulaula palena. ʻakika hiki koke komo iloko o ka cutaneous momona, ahu iho, no laila hoi e pono e koke paka e kaka ana i ka hoʻohuli ai i nā wahi.

I kia paʻa o ka 'ona hiki ana o na la poino i ka ÷ naehana hanu'āpana, a me nā maka. Accidentally hitting i ka loko, a hiki ma nāu kekahi palapala, methaneʻakika ke kumu loa gastroenteritis necrotic ano.

Ke kino koke pio a IeEeAUUXAAaO i ka waiwai. Eia naʻe, a me keia, E236 a me ka formaldehyde, a i hanaʻia ma ka ʻapu kōheoheoʻana me metanola, hoʻonāukiuki lesions ma ka optic nā aʻalolo, e alakai i ka makapo.

muravtinoyʻakika paʻakai i formates inoa. Paio hahana maoli nō me ka i kia sulfuricʻakika hiki aku ai i E236 degradable ma H2O a me ka CO i ua hoʻohana 'ia e lilo kalapona monoxide.

Industrially mākaukau formicʻakika mai ka paʻakai hydroxide a me ka kalapona monoxide.

Ka baila aʻela i wahi waiwai 100,7, ke kūpaleʻana - 8,25 degere.

At lumi kumu E236 decomposes e kalapona monoxide a me ka wai. E like me ka mana e akāka ai, i ka ikaika methane aku i aceticʻakika. Eia naʻe, ma muli o ia ka mea hiki, e hoʻomaka koke degrade mua, ka mea, ua hoʻohana 'ia e like me ka'ūheheʻe ka'āina pohihihi keia.

Ua Ua manaoio ia E236 ka loa hygroscopic. I loko o ia mea ka mea i loaʻa i ka? Iecaianoaaiiie o anhydrous hoʻomanaʻo ma ka hoʻohana 'ana i dehydrating reagents mea,ʻaʻole hiki.

Formicʻakika helu kuhi hui 'ana me nā hua ea.

E236 maemae ma luna ma mua o 99% hiki ke hoomakaukauia mai ka koʻana koko pāʻoihana, ka hoʻohana 'ana i kekahi mau-ke kahua distillation me ka hoʻohana' ana o butyricʻakika. Ke distillation mua eliminates ka bulk wai. Ke koena, e komo ka hola 77% -th waiwai. E pili kona playout 3 - 6 manawa i ka nui o butyricʻakika i loko o ke kino o ka azeotropic ukuhiia.

Ma ke kaʻina hana o ka weheʻana o kekahi ipu me E236 pono e maopopo manao. I ka ho'āhu formicʻakika nui puʻe hiki e ua loaʻa ma ka manawa lōʻihi ma ka moku.
