Yuav ua li cas tau txais los ntawm ethane chloroethane nyob rau hauv Organic Science News for KIDS
Nyob rau hauv thiaj li yuav to taub yuav ua li cas tau txais los ntawm ethane chloroethane yuav pib tsom xam kev txwv hydrocarbon ethane.
Qhia qhov tseemceeb txog ntawm ethane
Qhov no hydrocarbon muaj cov mis C2H6. Carbons nyob rau hauv lub molecule yog SP3 hybrid lub xeev. Qhov no yog thaws rov los nyob rau hauv lub cev thiab tshuaj thaj chaw ntawm lub substance. Nyob rau hauv zoo tib yam tej yam kev mob ntawm ethane gaseous tshuaj nws yog sparingly soluble nyob rau hauv cov dej. Zoo li tag nrho lwm cov mej zeej ntawm lub chav kawm ntawv ntawm alkanes, ethane muaj ib tug noo tib bonds. Qhov no yog thaws rov los nyob rau hauv lub tshuaj thaj chaw ntawm lub hydrocarbon. Nws yog tsis muaj peev xwm mus nkag rau hauv ib qho ntxiv cov tshuaj tiv thaiv, rau nws tso cai nkaus xwb ib tug tshaj dhau hloov chaw.
Lub peculiarity ntawm cov khiav
Cia peb piav qhia txog yuav ua li cas tau txais los ntawm ethane chloroethane. Rau qhov no nws yog tsim nyog los ua kev cai rau hauv lub tshuaj tiv thaiv ntawm ethane thiab tshuaj nyob rau hauv lub xub ntiag ntawm ib lub teeb quantum (tsa kub). Vim homolytic rupture vim cov tshuaj radicals yog tsim. Rau lub tsim ntawm dawb radicals yuav tsum tau ib tug tej yam siv ntawm lub zog.
Nws yuav yuav nyob rau hauv ntau txoj kev. Raws li ib tug embodiment ntawm radical tsim yuav xav txog thermal pyrolysis. Yog xav tau chloroethane los ntawm ethane, kab zauv yog sau ntawm ib tug kub ntawm txog 500 0 C. ntawd lub zog uas yog tso tawm thaum qhov no yog txaus mus ua txhaum lub bonds. Ib tug thib ob txoj kev ntawm txoj kev active radicals yog siv cov ultraviolet tawg.
Mechanism radical hloov
Xav txog li ethane tau txais chloroethane. Kab zauv cov tshuaj tiv thaiv hais raws li lub mechanism ntawm qhov kev txiav txim ntawm SR-alkanes nrog halogens. Nyob rau hauv cov roj theem nyob rau hauv cov tshuaj tiv thaiv ntawm ethane nrog chlorine chiv tshwm sim dissociation ntawm cov tshuaj nyob rau hauv UV. Qhov no kauj ruam yog hu ua tus pib, nws yog tsiag ntawv los ntawm tshwm sim ntawm hais ntawm active tshuaj radicals. Cov uas ua raws yog zuj ethane molecule, txoj kev ua hydrogen chloride, raws li zoo raws li ib tug ethyl radical C2H5.
Ntxiv cov kev sib tham txog yuav ua li cas tau txais los ntawm ethane chloroethane. Nyob rau hauv lub kauj ruam tom ntej lub ethyl radical yog reacted nrog chlorine molecule, txoj kev etanhlorid thiab lwm cov tshuaj radical. Hais tias nws yog muaj peev xwm yuav hnov mob dua, ntxiv saw tshuaj tiv thaiv kev voj voog. Qhov no yuav tsis nyob ntev yog hu ua hais tawm. Tus nqi ntawm cov active radicals ntawm no theem ntawm tus sis yog tsis tau hloov, thiab muab cia rau hauv tag nrho. Raws li qhov kawg ntawm lub voj voog ua ib tug thib peb cov tshuaj tiv thaiv kauj ruam, uas yog hu ua cov saw txiav. Nws implies ib tug kev sib tsoo free hais, uas ua rau tsim ntawm cov tshuaj tiv thaiv cov khoom.
daim ntawv thov
Lo lus teb rau lo lus nug ntawm yuav ua li cas tau txais los ntawm ethane chloroethane. Cia peb xav txog daim ntawv thov. Cov uas ua chloroethyl yog ib tug loj narcotic tshuaj. Nws yog siv raws li ib tug ua kom loog nyob rau hauv phais haujlwm. Tsuas yog ob los yog peb lub vib nas this nyob rau hauv thiaj li yuav txo tau cov lub cev muaj zog ua si.
Lub ntsiab tsis muaj peev xwm ntawm cov tshuaj yeeb dej caw, peb nco ntsoov tau ntawm overdose. Txawm tias ib tug me ntsis nce nyob rau hauv lub pub tus nqi ua rau teeb meem loj rau cov tib neeg lub cev. Niaj hnub no chloroethane xwb nyob rau hauv tej rooj plaub yog siv raws li ib tug narcotic tshuaj.
Yuav kom ib tug loj raws li nws yog nyob rau hauv coob raws li ib tug tshuaj pleev neeg sawv cev rau short-term nto tshuaj loog ntawm daim tawv nqaij. Tau txais nyob rau hauv daim tawv nqaij, lub yam khoom uas yog vaporized, muaj yog ib daim tawv nqaij hypothermia, nws rhiab heev txo, uas nws yuav tau nqa tawm lub incisions, i.e., mus nqa tawm me hauj lwm nto.
Tsis tas li ntawd, cov tshuaj yeeb dej caw yog siv rau cov yuav txo tau ntawm pruritus, cov kev kho mob ntawm thermal kub nyhiab, neuromyositis, cryotherapy o. Lub ampoule twb xub rhuab nyob rau hauv lub Palm, no ces qhia dav hlau mus rau lub daim tawv nqaij. Rau kho cov hom phiaj, cov txheej txheem yog nqa tawm ib zaug ib hnub twg rau 7-10 hnub.
