Mawu Oyamba
2-Ethylpyrazine ndi organic compound. Zotsatirazi ndikuyambitsa zina mwazinthu, ntchito, njira zokonzekera, ndi chidziwitso chachitetezo:
Katundu: 2-Ethylpyrazine ndi madzi achikasu otumbululuka komanso onunkhira ngati mphete za benzene. Ndi sungunuka kwambiri organic solvents pa firiji, koma pafupifupi insoluble m'madzi.
Ntchito: 2-Ethylpyrazine angagwiritsidwe ntchito ngati reagent ndi wapakatikati mu organic synthesis. Itha kugwiritsidwa ntchito mu kaphatikizidwe ka organic kukonzekera mankhwala osiyanasiyana, monga pyrazoles, thiazoles, pyrazines, ndi benzothiophenes. Itha kugwiritsidwanso ntchito ngati ligand pazitsulo zachitsulo komanso kaphatikizidwe ka utoto.
Njira yokonzekera: Pali njira ziwiri zokonzekera 2-ethylpyrazine. Imodzi imakonzedwa ndi zomwe methylpyrazine imapangidwa ndi vinyl. Zina zimakonzedwa ndi zomwe 2-bromoethane ndi pyrazine.
Zambiri zachitetezo: 2-ethylpyrazine nthawi zambiri imakhala ndi kawopsedwe kakang'ono pakagwiritsidwe ntchito bwino. Monga organic pawiri, ikufunikabe kusamaliridwa mosamala. Mukakhudza khungu ndi maso, iyenera kutsukidwa ndi madzi ambiri panthawi yake. Kukoka mpweya wa nthunzi yake kuyenera kupewedwa mukamagwiritsa ntchito kuti mukhale ndi mpweya wabwino. Iyeneranso kusungidwa pamalo ozizira, owuma, opanda mpweya wabwino ndikupewa kukhudzana ndi okosijeni, zidulo, ndi zochepetsera.
