Diethyl Etera - te whakamahi i roto i te rongoā

Hākawa o - hua whakauru o Hauwai ngota o te rōpū hydroxyl i roto i waiwaihā phenols ranei waro R tuwhena: R1-e-R2. Diethyl Etera - te tātai H3C-e-CH3. Hoki angamaheni hākawa poinanahatanga mekameka waiwaro, me te metamerism. Ko te tuatahi momo o te poinanahatanga tika branched waiwaro mekameka. Metamerism - momo o te poinanahatanga i roto i nei e rua atu hākawa ranei i te tātai rāpoi taua, engari he hanganga rāpoi rerekē, e tika ana ki te Radicals rerekē i runga i ngā taha e rua o te hāora "piriti".

Diethyl Etera: whiwhi

Kua rite Ethers synthetically (i roto i te āhua e kore ratou e tupu i roto i te āhua free). Ka taea te whakamahi ki te synthesize hākawa maha ngā huarahi: te maroketanga o waiwaihā te whakamahi i ngā waikawa kohuke, alcoholates o te tauhohe i ki te alkyl kōnakonako. Dimethyl me methyl Ethyl hākawa he kāwanatanga haurehu waihā, te māngai i muri torutoru - rongoā, teitei - totoka. Hākawa o ruarua wairewa i roto i te wai, engari ngā i roto i ngā whakarewa organic, me nga māngai toharite (diethyl Etere, dipropyl Etere, me propyl) - pai whakarewa organic. ngā āhuatanga ōkiko o ratou tēnā i runga i te taimaha rāpoi. Ko pai te whakauru Diethyl Etera ki te hinu waipiro, chloroform, benzene, Etere, me fatty. A, no te e hanga e tikanga rokiroki takahi pūhākawa i roto i te pūhui taikaha me te paitini - hydroperoxides.

Diethyl Etera whakamahia i roto i te rongoā. Kei te whakamahia te reira mo te inhalation rehunga. āhuatanga tēnei momo e te taahiraa excitation rehunga korerotia (roa'tu, mahi cardiac, faarahi iaia oro, papī catecholamine whakahohe, te kukū o te kūhuka i roto i nga piki toto, waikawa pyruvic me lactate, he secretory leva me nekeneke mahi o te wahi kūnatu). Me mōhio e ka whakamahi i tenei momo o te rehunga Etera āta puta, he reira rawa maha e tika ana ki te mau i te mahimahi me te nekeneke mahi kaha. He rehunga whānui kua he pānga matamaha i runga i te tinana tangata (uaua-relaxant, analgesic me te whakapōauau).

whakakitea hākawa Mahi Local rite whakaongaonga o mutunga karere, ai ite te manawanui he pānga tautauā. I roto i tenei whakaaro, i te tahi taime te whakamahia te reira i roto i te pūkaha ki te whakahaere i motility pekitīlia, me subcutaneous - mo te excitation o te manawa kahuki, me te whakapai ake i te tohanga. Inhalation rua pūhākawa mukākā nga Airways e ai te inhibition kahuki tuatahi o manawa, ka whakahohe te secretion o repe arahau. Hoki te wā tuatahi mō te Etera diethyl whakarehu inhalation i whakamahia e te tākuta Russian tino NI Pirogov, kaiwhakarewa o mara pokanga, i roto i te Crimean War (1853-1856 gg.).

Kei te ngāwari Diethyl Etera whenumi kiriuhi mucous o te wahi romahā, engari tae mai rehunga oti i muri atu i ki chloroform. pānga whakapōauau whakakitea anake i inhalation o 5-8% kohu Ethyl Etera, me te rehunga tonu puta i roto i te 30 meneti o te inhalation o te 10% o te ranunga. pānga whakapōauau o te tarukino ko i te kukū o i 110 ki te 150 mg ia 100 ml o te toto, puta pāpāngia romahā i te pokapū o te 200 mg / 100 ml o te toto. Tapeke iti tāoke Etera. Te ti'ai i te rehunga puta i muri i 20-40 meneti i muri i paipa o inhalation o Etere, engari ki noa te tinana mai i te torutoru noa haora. Engari Etera wahi romahā me te whatukuhu. Tata 50% o te tapeke excreted i roto i te tinana i roto i te 30-60 meneti tuatahi i muri i te rehunga. kia mea te reira e etahi o nga hua o te tauhohenga wai o diethyl Etera e taea te paetata i roto i ngā pāhare me ētahi atu lipids ki te maha nga ra.
