methyl 2H-1 2 3-triazole-4-carboxylate (CAS# 4967-77-5)
Mawu Oyamba
Methyl 1,2,3-triazole-4-carboxylic acid ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
Methyl 1,2,3-triazole-4-carboxylic acid ndi madzi achikasu opepuka komanso onunkhira kwambiri. Imasungunuka mu zosungunulira za organic monga ethanol ndi dimethylformamide. Zimakhala zokhazikika kutentha kwa firiji, koma zimawola pa kutentha kwakukulu kapena pansi pa kuwala.
Ntchito: Itha kugwiritsidwanso ntchito ngati chowongolera kukula kwa mbewu komanso chigawo cha zinthu zowoneka bwino.
Njira:
Njira yokonzekera yodziwika bwino ya methyl 1,2,3-triazole-4-carboxylic acid imapezeka pochita ndi phenylenediamine ndi formic anhydride pansi pa zinthu zamchere. Kukonzekera kwapadera kuli motere:
1) Onjezani phenylenediamine ndi formic anhydride ku njira ya alkaline, nthawi zambiri amagwiritsa ntchito sodium hydroxide kapena sodium carbonate monga alkaline wothandizira;
2) Pa kutentha koyenera, zomwe zimachitikazo zimachitika kwa maola angapo kuti ma reactants achitepo kanthu;
3) Mankhwalawa amasefedwa ndikuyeretsedwa ndi distillation kuti apeze methyl 1,2,3-triazole-4-carboxylate.
Zambiri Zachitetezo:
Methyl 1,2,3-triazole-4-carboxylic acid imakwiyitsa kwambiri komanso ikuwononga, ndipo kukhudzana ndi khungu, maso, kapena kupuma kwa nthunzi yake kungayambitse mkwiyo kapena mavuto ena azaumoyo. Zida zoyenera zodzitetezera (PPE), kuphatikiza magolovesi, zovala zodzitchinjiriza, ndi zida zoteteza kupuma, ziyenera kuvalidwa zikagwiritsidwa ntchito kapena kugwiridwa. Iyenera kugwiritsidwa ntchito pamalo olowera mpweya wabwino ndikupewa kukhudzana ndi oxidizing amphamvu kapena zinthu zoyaka moto. Mukakhudzana mwangozi, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupita kuchipatala mwamsanga.
