Taw qhia
5,6-Dichloronicotinic acid yog cov organic compound. Hauv qab no yog cov lus piav qhia ntxaws txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos mob: 5,6-Dichloronicotinic acid tsis muaj xim rau lub teeb daj daj lossis crystalline hmoov.
- Solubility: soluble hauv cawv thiab ethers, me ntsis soluble hauv dej.
Siv:
- 5,6-Dichloronicotinic acid feem ntau yog siv los ua tshuaj reagent raws li oxidant, txo tus neeg sawv cev thiab catalyst hauv cov organic synthesis tshuaj.
Txoj kev:
- 5,6-dichloronicotinic acid feem ntau tuaj yeem npaj los ntawm nitroreduction ntawm p-nitrophenol. Nitrophenol yog kho nrog nitrous acid los tsim 5,6-dinitrophenol. Tom qab ntawd, 5,6-dinitrophenol raug txo mus rau 5,6-dichloronicotinic acid siv cov tshuaj chlorine lossis nitroreducing agents.
Cov ntaub ntawv kev nyab xeeb:
- Cov plua plav lossis cov muaju ntawm 5,6-dichloronicotinic acid muaj qhov ua rau khaus thiab ua rau khaus rau ntawm qhov muag, tawv nqaij thiab ua pa.
- Hnav cov khoom tiv thaiv tus kheej tsim nyog xws li looj tsom iav, hnab looj tes thiab lub tshuab ua pa thaum siv.
- Tsis txhob nqus cov plua plav thiab tsis txhob kov cov tawv nqaij.
- Thaum lub sijhawm khaws cia thiab tuav, tsis txhob sib cuag nrog cov neeg ua haujlwm oxidizing muaj zog lossis cov khoom tawg yooj yim.
- Nyob rau hauv rooj plaub uas raug mob 5,6-dichloronicotin, yaug qhov chaw raug mob tam sim ntawd nrog dej txaus thiab nrhiav kev kho mob.
