Formic aldehyde. Awina formic aldehyde

Formic aldehyde a formaldehyde - mea he colorless kinoea me ka pahi, kaʻawaʻawa ano ala. He mea nui wailana i loko o ka wai a me ka waiʻona mai ke kino. Formaldehyde mea nuiʻawahia, a hiki i loko o ke kanaka kino lesions. Eia hou, ka mea, ua manaoia he carcinogen.

Formaldehyde - ka lālā mua o ka homologous puke, i nā aliphatic formic aldehyde. Formicʻakika kekahi hōʻike waiwai o keia pae.

Formaldehyde mea hiki ke komo i loko o nā mea a pau o na reactions i e ano o ka homologous moʻo o aliphatic aldehydes. Me me ka nucleophiles. Ua ua no hoi me ka hoemi konohiki pili. Kēia meaʻano nui ku pono ana i ka mea i ka formaldehyde mea haʻahaʻa huina'ine nuʻa ma ka o carbon nā'ātoma. Mahalo i kēia hiʻona o ka 'ole ia mea loa paakiki ole e komo i loko o Nine Inch reactions me ke ahiahi, o ka loa nawaliwali nucleophiles. Kēia wehewehe i ka mea i loko o koʻana koko formic aldehyde ua loaʻa i loko o ka hydrated moku'āina.

Kēia mea mea he mea haʻilula. Formic aldehyde ma ka Nine Inch 'ōlelo nana me keia: HCHO. I ka papa kuhikuhiE hanalima iaoiaeii o kona? Iecaianoaaiiuo - o ka'okesaside o metanola. Kēia naoh ua lawe mai ka hoʻohana 'ana i ka kala hōʻeleu. Koi Mahana - 650 degere. metanola'okesaside ia lŘlŘ ma ka lewa puʻe.

Kēia kaʻina mea, ua hala loa o ka lōʻihi manawa ua i hoʻohana na wahi a pau. Ua ua pono E ke Kumu. Kahi o 80% formaldehyde loaa ia ma ka oxidizing naoh o metanola. Naʻe, i kēia mea,ʻaʻole ka mea wale ala. A nei ka mea nui i hiki hou i olelo mua iaʻi hana. Ua Ua ka nānā i ka pono o ka hao-molybdenum catalysts. Ma keia hihia i ka makemake mahana pae ua hoemi ia i ka 300 degere, a uaʻaneʻane halved.

I ikeia o kekahi hanalima kaʻina - ka'okesaside o methane. Ma muli o ia i kēiaʻano mea haʻilula: formic aldehyde ua loaa ia ma ka puʻe o 1-2 MPa i 450 degere. Ka hōʻeleu ia Aluminum posapahate.

Methanediol - koʻana koko formaldehyde pāʻoihana, i ke kumu no kumuʻiʻo denaturation. Kēia mea e like ai apono 'i ka hoʻohana' ana i ka waiwai me ka tanning konohiki i loko o ka hana o kaʻili mau. Ua Ua hoʻomano hoʻohana pū i loko o ka? Iecaianoaaiiie o Film-films. Aie i ka mea ikaika tannic waiwai formaldehyde ua ikeia me he antiseptic. Ua Ua hoʻomano hoʻohana i laau lapaau. Ma muli o ia paka ia antiseptic hoomakaukau, e like me "Formagel" a me ka "Formidron". No ka hala loa o ka lōʻihi manawa, formic aldehyde hoʻohana i kālaimeaola no ka papaa o biomaterials, e like me nā loko holoholona a me kino.

Currently, loaa formic aldehyde waiwai laau, a, o ka papa, i ka lako hana. Ua ua hoʻohana 'ia no ka? Iecaianoaaiiie o kēpau melaminokarbamidoformaldegidnyh. Ka mea, i hoʻohana 'ia i loko o ka hana o ka huna papa, plywood a me nā hale pono hana.

I ka ho'āhu formic aldehyde E e kaulana ia ma ke anawela ma lalo 10 degere pāʻoihana i ao, a me ka keʻokeʻo precipitate ikeia. Nō hoʻi, formaldehyde ua reacted me ka oxygen. E like me ka hopena, i hanaʻia ma muli o ia ka mea hou lālā ai manamana ai ke kaula gula initiators.

ʻawahia waiwai

Pela, ua hoomakaukauia ia e'okesaside o metanola a me ka methane formaldehyde. Oiaio no, ka mea, i ka i lawa ke kiekie loa o kaʻawahia. Formic aldehyde kuhikuhi e loli ai i ka aaiaoe mea. Mai keia waiwai nui ae aku a me ka reproductive nā loko. Akā, o ka papa, pinepine ia airway poino,ʻili a me ka maka.

Formaldehyde mea pilikia ma ka mea i ka mea, i ka hopena maikaʻi ia ma luna o ka CNS.

Formic aldehyde wale iʻawahia - 60-90 ML waiwai (kaumaha ma muli o ke kaupaonaʻana), trapped loko, pono ka make. Symptoms o kaʻapu kōheoheo nā:

• mau moe;
• mae o ka ili integument;
• unconsciousness;
• CNS kaumaha;
• pokole o ka hanu;
• loa headache;
• cramps, o ka oi aku i ka po.

Formic aldehyde hopena ma luna o ke kanaka kino

Ka hoʻohana a formic aldehyde i loko o ka? Iecaianoaaiiie pinepine hele aku ai i loli iki degere o kaʻapu kōheoheoʻana o nā limahana. Me ka ikaika inhalation lesions, oa ma inhalation, mālama nō conjunctivitis a me ka huʻi 'ano o ka bronchitis, i kekahi manawa, hiki aku ai i pulmonary edema. Symptomatology i hooloihi ae i waiū o ka formaldehyde e wale hoʻonui. Ma hope o ka pōkole manawa, eia na hoailona o ka ino a me ka CNS kaumaha. It E e hoike i ka ikaika pōniuniu, e manao ana o ka makau aicieeaao, ka gait lilo unsteady, a ma ka po, i ke kanaka hiki ia i ke kāʻili 'ana.

Inā i kaʻapu kōheoheoʻana ana ma ka waha, ka mea mua symptom, e puhi i ka mucous membranes o ka digestive'āpana. Ka mea, e hoike mai ia ia iho i loko o ka palapala o ka eha, he ahi ka waiʻona ma loko o ka puu, a me ka esophagus. Man Kahalaopuna ikaika retching, ke kaupaonaʻana, hoowahawaha mai o ka'ōpū, e komo i ke koko. I loa hoopii, hoʻomōhala laryngeal edema malama reflex naehana hopu.

I ka maʻiʻapu kōheoheoʻana i loko o ka poe liilii, nā hoʻohui like i loko o kānaka he mea he ikaika kaumaha poho, noʻonoʻo stimulation, pilikia makapō haunaele, Kanikani'āʻula, a me ka maʻi headaches.

Kaʻapu kōheoheo me ka formaldehyde

Formic aldehyde loa olelo i loaʻa i loko o ka lewa. Eiiiaiey eiaao a? Aaiuo komo ma ka hana e pili ana i ka hana o kemikala kēpau, a me ka paʻa a me ka lōʻihi-kau waiū e formaldehyde ohu hiki kaʻapu kōheoheo. Pinepine i loko o ka mua hana lā i kekahi kanaka ua hoailono aku la dermatitis ma luna o ka maka, lima. Ke alo aku o ka formaldehyde i loko o ke kino hiki ke ike ma ka moku'āina o ka mea hōʻemi o kui - e hoopalupalu mai a me ka lilo brittle.

Eczema a dermatitis i e ka allergicʻano. Ma hope o kekahi kanaka ua waiho wale aku no i kaʻapu kōheoheoʻana, ka mea, ua hanaʻia ma ka formic aldehyde ikaika pā lonoaʻili. Aia ka hōʻike i formaldehyde he kūlana e loli ai i ka functioning o ka reproductive'ōnaehana o ka wahine kino.

I ka hoʻohana 'ana o formaldehyde i loko o nā mea hoʻonani

Ke formaldehyde maʻiʻo ua aeia'ku like me ka preservative i loko o nā mea hoʻonani, akā, kona lehulehu e ole oi 0,1%. Formic aldehyde paha e noho ma ka toothpaste holika no kino, maka a me na lima.

¶ A i loko o pharmacology, i loko o kekahi mau mea o ka pale excessive sweating ke mea formaldehyde. Kona allowable lehulehu o - 0.5%. Kēia waiwai a pau - He maikai antiseptic, a hiki i ka uuku na mea ia mea hiki ke pepehi anakahi iki-meaola. Ua Ua pololei papaia e kau i kekahi mea poni maluna iho o ka ili a pau ina ka mea, he hapa ia o ka 5% formaldehyde. He fraught me keʻano o ka dermatitis a me allergic reactions. No hoi ua i hoʻohana formic aldehyde no ka hoopakele ana i mea hoʻonani huahana, ina ka mea, e kūʻai me aerosols a me nā paipu,.

A pau i nā huahana ma luna o lākou lepili e komo 'ike e pili ana i ka maʻiʻo o ka pilikia' ona, i ke ahiahi ina dala o 0,05%. I mea, a hiki i kēia lā,ʻaʻole, ua möakäka hou like me ka pāʻoihana o formaldehyde e loli ai i kaʻili, akā, ka mea, ua ike ia i loko o na holoholona ka mea, ua ulaula mai a me ka flaky.

Carcinogenic formic aldehyde

Ua Ua ikeia i ua reacted formaldehyde me ka selenium, a me ke komo o ka loa i kia sulfuricʻakika. I ka hopena o ka ethersulfates-4-tetradetsilidioksan. Kēia mea me ka luna 'kapaia ma hope o aaioee ka barium'okesaside hydrate i maikai loa detergent. Ua makemake mea, heaha ka ka pilikia? Akā, formaldehyde ua hou a hiki i ka papa inoa o ka waiwai me ka carcinogenic waiwai. Oiai ke degere o ka pilikia ka mea, i ole, ua hoʻokumu 'ia, ka mea i pono, e lawe i mooolelo o ka mea i ka formic aldehyde mea make no na holoholona. E like me ka oihana ike o na mea he nui iao? Ioauoa o ko ke ao nei, i ka pilina ma waena o ka hoʻohana 'ana o formaldehyde i loko o ka hana o ka pena, kēpau, nā mea hana o ka home, Ka lula ea Ke, a me ka hanana o ka maʻi' aʻai hikoko i loko o kānaka hoao.
