Diethyl Etera - i ka hana ma ka laau lapaau

Nā mea kemika o - hakahaka huahana o ka hydrogen'Ātoma o ka hydroxyl pae i ka waiʻona mai ke kino a me phenols kalapona'ano'ē R: R1-O-R2. Diethyl Etera - ka haʻilula H3C-O-CH3. No ka typical ester isomerism hydrocarbon kaulahao a me ka metamerism. Ka mua ʻano o ka isomerism hālāwai hoʻolohe ai manamana hydrocarbon kaula. Metamerism -ʻano o ka isomerism ma i elua a oi ester i ka ia hakakino haʻilula, akā, he okoa hakakino 'ole, ka hoʻopiʻi ai i kaʻokoʻa radicals ma na aoao a elua o ka oxygen ma "alahaka".

Diethyl Etera: loaa

i hoomakaukau synthetically la o Etera (ma ka ano ka mea, e mai ana i loko o ka noa moku'āina). E synthesize nā mea kemika hiki ke hoʻohana 'mau aoao: ka dehydration o ia ka waiʻona mai ka hoʻohana mea pōhaku nāʻakika, alcoholates o reacting me ka halogen alakaila. Dimethyl a me ka meto'eto nā mea kemika e gaseous moku'āina, ka mea e hiki mai ana mau lunamakaainana - pāʻoihana, kiekie - puaʻa hiwa. Nā mea kemika o poorly wailana i loko o ka wai, akā, ma ka haiia i loko o ke aloha nā'uheheʻe, a me ka awelika lunamakaainana (diethyl Etera, dipropyl me Etera, a me ka propyl) - maikaʻi ke aloha nā'uheheʻe. Helu waiwai o ia oko ma ka hakakino kaumaha. Diethyl o Etera ua pono hui me ka waiʻona, chloroform, benzene, me Etera, a me ka momoma mea kāhinu,. I ka wā i hanaʻia, ke 'aʻe' ester pūnaewele kūlana ma ka pahū a me kaʻawahia i huiʻia - hydroperoxides.

Diethyl Etera hoʻohana 'ia ma ka laau lapaau. Ua Ua hoʻohana 'ia no ka inhalation anesthesia. Kēiaʻano Ua wehewehe aku ma ka olelo anesthesia excitationʻanuʻu (listen cardiac haʻawina, maoli he vascular leo, ho'ā 'catecholamine excretion, i ka lehulehu o ka monakō koko i loko o ka piʻi pū koko, pyruvicʻakika a me ka lactate, mea inhibited secretory a me Hawaii hana o ka digestive'āpana). Eʻoluʻolu, e makaala i ka ia ka hoʻohana 'ana i kēia' ano o Etera anesthesia ia lŘlŘ lohi, ia mea nui pinepine pono e malama i ka ikaika a me ka arousal Hawaii hope. A mau anesthesia i ka multifaceted ia ma luna o ke kanaka kino (Muscle-relaxant, analgesic a me ka narcotic).

Local hana ester hoike aku i stimulation o nā aʻalolo a hāʻule pahū wale, ai ke hoʻomanawanui i ka hoao ana i ka huʻihuʻiʻana kanawai. Ma keia manao, i kekahi manawa ka mea, ua hoʻohana 'ia i loko o ka Hawaii, e hooponopono i gastric motility, a me ka subcutaneous - no ka excitation o ka reflex hanu a me ka hoʻoikaika' ana i holo. Inhalation paʻa ester nāuki mai i ka Hawaiian Airlines mea e hookomo ana i ka mua reflex inhibition o ka hanu 'ana, a laila, haʻalele ka secretion o bronchial glands. No ka mea manawa mua no ka inhalation anesthetic diethyl o Etera i hoʻohana 'ia e ka poʻokela Lūkini surgeon NI Pirogov, i hoʻokumu o ke kahuaʻoki kino, i ka Crimean War (1853-1856 GG.).

Diethyl Etera ua hooholo koke paka mucous membranes o ka naehana'āpana, akā, piha anesthesia hele mai ma hope ma mua me ka chloroform. Narcotic ai hoike wale ma inhalation o 5-8%'eto Etera ka ohu a me ka piha anesthesia ia lŘlŘ i loko o 30 minuke o inhalation o 10% o ka läÿau,. Narcotic hopena o ka lāʻau mea ma ka lehulehu o ka mai 110 a hiki i 150 mg no 100 ml o ke koko, naehana lōlō ia lŘlŘ ma ka waena konu o ka 200 mg / 100 ml o ke koko. Ka lōʻihi o kaʻawahia Etera wale no mailuilu haalele. Hoala mai la mai ka anesthesia ia lŘlŘ ma hope o 20-40 minuke ma hope o cessation o inhalation o Etera, akā, i ka maʻamau kino wale i kekahi mau hola hele mai. Eia nae, me Etera naehana'āpana, a me nā puʻupaʻa. Kahi o 50% o ka huina excreted i loko o ke kino i ka mea mua 30-60 minuke ma hope o ka anesthesia. Ua pono e mai la oia i kekahi o nā huahana o hydrolysis o diethyl Etera hiki ke IIeEeAIEUIeXAIIUE ma triglycerides a me nā lipids i kekahi mau lā.
