trans-2-Hexen-1-Al Diethyl Acetal (CAS #54306-00-2) yambitsani
katundu wakuthupi
Maonekedwe: Nthawi zambiri imawoneka ngati madzi owoneka bwino opanda mtundu mpaka achikasu, zomwe zimapangitsa kuti zikhale zosavuta kugwira ntchito popanga mankhwala monga kutengera zinthu ndi kusakanikirana.
Fungo: Lili ndi fungo lapadera la zipatso, lomwe ndi labwino komanso lachilengedwe. Izi zakopa chidwi kwambiri pazamafuta onunkhira, ndipo zitha kugwiritsidwa ntchito ngati zopangira zopangira kuphatikiza kukoma kwa zipatso.
Kusungunuka: Kutha kusungunuka bwino muzosungunulira zambiri za organic, monga ethanol, etha, acetone, ndi zina zotero, zomwe zimapangitsa kuti zikhale zosavuta kusakaniza ndi kukhudzana ndi zina zowonongeka mu machitidwe a organic synthesis reaction; Kusungunuka m'madzi kumakhala kochepa, zomwe zimagwirizana ndi lamulo la kusungunuka kwa mankhwala a organic okhala ndi mpweya wambiri wa carbon.
Malo owiritsa: Ili ndi magawo enaake owiritsa, omwe ndi maziko ofunikira pakulekanitsa ndi kuyeretsa ntchito monga kusungunula ndi kukonza. Malo otentha a zitsanzo okhala ndi zoyera zosiyanasiyana amatha kusiyana pang'ono, ndipo khalidwe ndi chiyero cha mankhwala akhoza kuyesedwa poyambirira poyesa molondola mfundo yowira.
4, Chemical katundu
Acetal hydrolysis reaction: Pansi pa acidic mikhalidwe, kapangidwe ka diethylacetal mu molekyulu imakonda hydrolysis, kupanga magulu a aldehyde ndi ethanol kachiwiri. Khalidweli nthawi zambiri limagwiritsidwa ntchito mu kaphatikizidwe ka organic potembenuza gulu logwira ntchito kapena chitetezo chamagulu a aldehyde, ndipo amamasulidwa panthawi yoyenera kutenga nawo gawo pazotsatira.
Pawiri chomangira chomangira anachita: Mpweya mpweya wawiri zomangira akhoza kukhala malo yogwira ndi kukumana zochita Kuwonjezera ndi haidrojeni, halogens, etc. Polamulira mmene zinthu ndi reagent mlingo, mndandanda wa zotumphukira akhoza kusankha anakonza, kulemeretsa zosiyanasiyana mankhwala.
Oxidation reaction: Pogwira ntchito ya okosijeni yoyenera, mamolekyu amatha kukhala ndi okosijeni, kusweka kwa zomangira ziwiri, kapenanso makutidwe ndi okosijeni amagulu a aldehyde kuti apange zinthu zofananira za okosijeni, zomwe zimapereka njira yopangira zinthu zina zovuta.
5, kaphatikizidwe njira
The wamba kupanga njira ndi kuyamba ndi trans-2-hexenal ndi kuchita izo ndi anhydrous Mowa pamaso pa catalysts acidic monga youma wa hydrogen kolorayidi mpweya, p-toluenesulfonic acid, etc. Zimene ndondomeko amafuna okhwima kutentha kulamulira, kawirikawiri mu kutentha kwapang'onopang'ono mpaka kutentha kwa chipinda, kuteteza kuti zisachitike; Panthawi imodzimodziyo, m'pofunika kuonetsetsa kuti malo a anhydrous ali ndi anhydrous, chifukwa kukhalapo kwa madzi kungathe kusintha momwe aldol amachitira ndi kukhudza zokolola. Atamaliza anachita, chothandizira zambiri neutralized ndi njira zamchere, ndiyeno analekanitsidwa distillation, rectification ndi njira zina kupeza mkulu-chiyero chandamale mankhwala.
