Mawu Oyamba
2-Amino-3-cyanopyridine ndi organic pawiri yemwe kapangidwe kake ndi C6H5N3. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Katundu: 2-Amino-3-cyanopyridine ndi yolimba, nthawi zambiri yoyera kapena yopepuka ya crystalline yachikasu. Ndiwokhazikika kutentha kwa chipinda ndipo imakhala ndi kusungunuka kochepa m'madzi.
Cholinga: 2-Amino-3-cyanopyridine angagwiritsidwe ntchito ngati zofunika zopangira ndi wapakatikati mu kaphatikizidwe organic. Nthawi zambiri amagwiritsidwa ntchito popanga mitundu yosiyanasiyana yamagulu achilengedwe, monga mankhwala, mankhwala ophera tizilombo ndi utoto. Kuonjezera apo, amagwiritsidwanso ntchito kwambiri popanga utoto wazitsulo wa phthalocyanine ndikukonzekera mankhwala a heterocyclic.
Njira yokonzekera: 2-Amino-3-cyanopyridine nthawi zambiri imakonzedwa pogwiritsa ntchito benzaldehyde monga poyambira ndikudutsa njira zingapo zopangira. Njira yomwe imagwiritsidwa ntchito kwambiri ndi zomwe benzaldehyde ndi aminoacetonitrile pansi pa acidic kuti apange 2-Amino-3-cyanopyridine.
Chidziwitso chachitetezo: Mukamagwiritsa ntchito ndikugwiritsa ntchito 2-Amino-3-cyanopyridine, njira zotsatirazi zodzitetezera ziyenera kutsatiridwa: Zitha kukwiyitsa maso, khungu ndi kupuma thirakiti, kotero kukhudzana mwachindunji kuyenera kupewedwa panthawi yogwira ntchito. Iyenera kugwiritsidwa ntchito pamalo olowera mpweya wabwino ndikupewa kutulutsa fumbi lake. Nthawi yomweyo, pogwira ndi kusunga, pewani kukhudzana ndi zinthu zovulaza monga ma okosijeni, ma acid amphamvu ndi maziko amphamvu kuti mupewe zoopsa zomwe zingachitike. Pogwiritsira ntchito mankhwalawa, njira zotetezera ziyenera kutsatiridwa mosamalitsa. Ngati wamwedwa molakwika kapena atakoweredwa molakwika, pitani kuchipatala munthawi yake.
