Mawu Oyamba
5,6-Dichloronicotinic acid ndi organic pawiri. Zotsatirazi ndi kufotokozera mwatsatanetsatane za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
- Maonekedwe: 5,6-Dichloronicotinic acid imakhala yopanda utoto mpaka makhiristo achikasu owala kapena ufa wa crystalline.
- Kusungunuka: kusungunuka mu ma alcohols ndi ma ether, kusungunuka pang'ono m'madzi.
Gwiritsani ntchito:
- 5,6-Dichloronicotinic asidi nthawi zambiri ntchito monga reagent mankhwala monga okosijeni, kuchepetsa wothandizila ndi chothandizira mu organic synthesis zimachitikira.
Njira:
- 5,6-dichloronicotinic acid nthawi zambiri imatha kukonzedwa ndi nitroreduction ya p-nitrophenol. Nitrophenol amathandizidwa ndi nitrous acid kuti apange 5,6-dinitrophenol. Kenako, 5,6-dinitrophenol imachepetsedwa kukhala 5,6-dichloronicotinic acid pogwiritsa ntchito chlorine kapena nitroreducing agents.
Zambiri Zachitetezo:
- Fumbi kapena makhiristo a 5,6-dichloronicotinic acid amakhala ndi zotsatira zokwiyitsa ndipo angayambitse kuyabwa m'maso, khungu ndi kupuma.
- Valani zida zodzitetezera zoyenera monga zovala zamaso, magolovesi ndi zopumira mukamagwiritsa ntchito.
- Pewani kutulutsa fumbi ndikupewa kukhudza khungu.
- Pakusunga ndi kusamalira, pewani kukhudzana ndi ma oxidizing amphamvu kapena zinthu zoyaka moto.
- Mukakumana ndi 5,6-dichloronicotin mwangozi, sambitsani malo omwe akhudzidwa nthawi yomweyo ndi madzi ambiri ndikupempha upangiri wamankhwala.
