Mawu Oyamba
Ethyl ethynyl carbinol (Ethyl ethynyl carbinol) ndi organic pawiri ndi mankhwala chilinganizo C6H10O. Zimapezedwa powonjezera gulu la hydroxyl (gulu la OH) ku pentyne. Maonekedwe ake akuthupi ndi awa:
Ethyl ethynyl carbinol ndi madzi opanda mtundu komanso onunkhira. Amasungunuka m'madzi ndi zosungunulira zambiri monga ma alcohols, ethers ndi esters. Ili ndi kachulukidwe kakang'ono, ndi yopepuka kuposa madzi, ndipo ili ndi malo otentha kwambiri.
Ethyl ethynyl carbinol ali ndi ntchito zina mu organic synthesis. Itha kugwiritsidwa ntchito ngati zoyambira komanso zapakatikati pakuphatikizika kwachilengedwe, ndipo nthawi zambiri imagwiritsidwa ntchito popanga mankhwala okhala ndi carbonyl. Itha kutenga nawo gawo mu alkyd esterification, olefin kuwonjezera, saturated hydrocarbon carbonylation reaction. Kuphatikiza apo, 1-pentin-3-ol itha kugwiritsidwanso ntchito popanga utoto ndi mankhwala.
Njira kukonzekera Ethyl ethynyl carbinol akhoza kuchitidwa ndi masitepe zotsatirazi: choyamba, pentyne ndi sodium hydroxide (NaOH) anachita Mowa kupanga 1-pentin-3-ol sodium mchere; ndiye, 1-pentin-3-ol mchere wa sodium umasandulika kukhala Ethyl ethynyl carbinol mchere ndi acidification anachita.
Mukamagwiritsa ntchito ndikugwiritsa ntchito Ethyl ethynyl carbinol, muyenera kulabadira mfundo zotsatirazi zachitetezo: Zimakwiyitsa ndipo zimatha kuyambitsa kukwiya komanso kuvulaza khungu ndi maso, kotero muyenera kuvala zida zoyenera zodzitetezera, monga magolovesi ndi magalasi. Kuonjezera apo, ndi yoyaka ndipo iyenera kupeŵedwa kuti isagwirizane ndi moto wotseguka kapena magwero a kutentha kwakukulu, ndikusungidwa bwino. Kusamalira kwina kulikonse kapena kusungirako komwe kumakhudzana ndi gululi kuyenera kuchitidwa motsatira njira zotetezeka zogwirira ntchito.
