Mawu Oyamba
Ndi organic pawiri ndi mankhwala chilinganizo C6H5ClN2O3.
Chilengedwe:
-Maonekedwe: Yoyera mpaka yolimba yachikasu
- Malo osungunuka: 44-46 ° C
-Powira: 262°C
-Kusungunuka mu: mowa ndi ether, osasungunuka m'madzi
Gwiritsani ntchito:
ndizofunikira zapakatikati, zomwe zimagwiritsidwa ntchito kwambiri pakupanga organic synthesis. Itha kugwiritsidwa ntchito popanga mitundu yosiyanasiyana ya biologically yogwira, monga mankhwala, utoto ndi mankhwala ophera tizilombo.
Njira Yokonzekera:
Synthesis imatha kuchitika m'njira zotsatirazi:
1. 2-Nitro-6-formylpyridine inapezedwa pochita 2-nitro-6-nitro-pyridine ndi sulfuric acid.
2. Zomwe 2-nitro-6-formylpyridine ndi chloromethyl ether pansi pa zochita za alkali zimapangidwa.
3. Masitepe oyeretsedwa ndi crystallization adachitidwa kuti apeze mankhwala oyera.
Zambiri Zachitetezo:
Ndi chinthu chowopsa chomwe chingayambitse kuyabwa ndi kuyabwa ndi kuyanika kapena pokoka mpweya. Mukamagwira ntchito, valani zodzitetezera zoyenera monga magolovesi, magalasi ndi zovala zodzitchinjiriza, ndikuwonetsetsa kuti ntchitoyi ikuchitika pamalo abwino mpweya wabwino. Pakusungirako ndikugwira, kukhudzana ndi ma okosijeni amphamvu ndi zinthu zoyaka moto ziyenera kupewedwa.
