Mawu Oyamba
2-nitrobenzenesulfonyl chloride (2-nitrobenzenesulfonyl chloride) ndi organic pawiri ndi mankhwala chilinganizo C6H4ClNO3S. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
1. Chilengedwe:
2-nitrobenzensulfonyl chloride ndi kristalo wachikasu wolimba wokhala ndi fungo loyipa. Ndi bwino sungunuka m'madzi, koma mosavuta sungunuka mu organic solvents. Pa kutentha kwambiri, kuwala ndi chinyezi, 2-nitrobenzensulfonyl chloride ikhoza kuwola.
2. Gwiritsani ntchito:
2-nitrobenzenesulfonyl chloride nthawi zambiri amagwiritsidwa ntchito ngati reagent yofunika mu kaphatikizidwe ka organic. Itha kugwiritsidwa ntchito popanga zinthu zina organic, monga O-nitrobenzenesulfonamide ndi zina zotero. Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati chapakatikati pa utoto, utoto ndi mankhwala ophera tizilombo.
3. Njira yokonzekera:
Kukonzekera kwa 2-nitrobenzenesulfonyl chloride nthawi zambiri kumachitika pochita p-nitrobenzene sulfonic acid ndi madzi a thionyl chloride. Zimene ikuchitika pa kutentha otsika, ndi zimene mankhwala kawirikawiri olekanitsidwa ndi crystallization.
4. Zambiri Zachitetezo:
2-nitrobenzensulfonyl chloride imakwiyitsa ndipo iyenera kusungidwa kutali ndi maso ndi khungu. Samalani njira zodzitetezera panthawi yomwe mukugwira ntchito, monga kuvala magolovesi oteteza mankhwala ndi magalasi. Pewani kukhudzana ndi ma okosijeni ndi zinthu zoyaka moto posungira ndikugwira kuti mupewe ngozi ya moto ndi kuphulika. Mukamagwiritsa ntchito kapena kutaya, chonde tsatirani malamulo oyenera komanso malangizo ogwiritsira ntchito chitetezo.
