Taw qhia
2-nitrobenzenesulfonyl chloride (2-nitrobenzenesulfonyl chloride) yog cov organic compound nrog cov tshuaj formula C6H4ClNO3S. Cov hauv qab no yog cov lus qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab kev nyab xeeb cov ntaub ntawv:
1. Xwm:
2-nitrobenzensulfonyl chloride yog daj crystalline khoom nrog ib tug pungent tsw. Nws tsis zoo soluble hauv dej, tab sis yooj yim soluble hauv cov kuab tshuaj organic. Nyob rau hauv qhov kub thiab txias, lub teeb thiab av noo, 2-nitrobenzensulfonyl chloride yuav decompose.
2. Siv:
2-nitrobenzenesulfonyl chloride feem ntau yog siv los ua ib qho tseem ceeb reagent hauv organic synthesis. Nws tuaj yeem siv los ua ke rau lwm cov organic sib txuas, xws li O-nitrobenzenesulfonamide thiab lwm yam. Tsis tas li ntawd, nws kuj tseem siv tau los ua ib qho nruab nrab rau dyes, pigments thiab tshuaj tua kab.
3. Txoj kev npaj:
Kev npaj ntawm 2-nitrobenzenesulfonyl chloride feem ntau yog tau los ntawm reacting p-nitrobenzene sulfonic acid nrog kua thionyl chloride. Cov tshuaj tiv thaiv yog nqa tawm ntawm qhov kub thiab txias, thiab cov khoom siv tshuaj tiv thaiv feem ntau yog cais los ntawm crystallization.
4. Cov ntaub ntawv kev nyab xeeb:
2-nitrobenzensulfonyl chloride yog khaus thiab yuav tsum tau ceev kom deb ntawm qhov muag thiab tawv nqaij. Ua tib zoo saib xyuas kev tiv thaiv tus kheej thaum ua haujlwm, xws li hnav cov hnab looj tes tiv thaiv thiab tsom iav. Tsis txhob kov cov oxidants thiab cov khoom siv hluav taws xob thaum lub sijhawm khaws cia thiab tuav kom tsis txhob muaj kev pheej hmoo ntawm hluav taws thiab tawg. Thaum siv lossis pov tseg, thov ua raws li cov kev cai cuam tshuam thiab cov lus qhia kev nyab xeeb.
