Taw qhia
m-Nitrobenzenesulfonyl chloride yog cov organic compound uas nws cov tshuaj formula C6H4ClNO4S. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm m-nitrobenzene sulfonyl chloride:
Xwm:
m-Nitrobenzenesulfonyl chloride yog lub teeb daj daj nrog cov ntxhiab tsw. Nws ruaj khov ntawm chav tsev kub, tab sis cov tshuaj tiv thaiv decomposition tshwm sim thaum rhuab. Cov tshuaj no yog flammable thiab insoluble hauv dej, tab sis tuaj yeem yaj hauv cov kuab tshuaj organic.
Siv:
m-Nitrobenzenesulfonyl chloride yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis. Nws yog feem ntau siv nyob rau hauv cov synthesis ntawm cov organic tebchaw xws li tshuaj, dyes thiab tshuaj tua kab. Tsis tas li ntawd, nws kuj tseem siv tau los ua cov tshuaj chlorination reagent, reagent rau kev tshem tawm ntawm thiols, thiab ib qho tseem ceeb reagent hauv tshuaj ntsuam xyuas.
Txoj kev:
m-Nitrobenzenesulfonyl chloride tuaj yeem npaj los ntawm iodination cov tshuaj tiv thaiv ntawm p-nitrobenzenesulfonyl chloride. Cov kauj ruam tshwj xeeb yog kom yaj nitrophenylthionyl chloride hauv chloroform, tom qab ntawd ntxiv sodium iodide thiab ib qho me me ntawm hydrogen iodide, thiab ua kom sov cov tshuaj tiv thaiv rau lub sijhawm kom tau txais m-nitrobenzenesulfonyl chloride.
Cov ntaub ntawv kev nyab xeeb:
m-Nitrobenzenesulfonyl chloride yog ib yam tshuaj lom uas ua rau tawv nqaij, qhov muag thiab ua pa. Thaum ua haujlwm, tsis txhob sib cuag nrog daim tawv nqaij thiab ob lub qhov muag, thiab xyuas kom meej tias kev ua haujlwm tau ua nyob rau hauv qhov chaw muaj cua zoo. Cov cuab yeej tiv thaiv tus kheej xws li hnab looj tes tiv thaiv, tsom iav kev nyab xeeb thiab lub ntsej muag tiv thaiv yuav tsum hnav thaum siv cov khoom siv. Tsis tas li ntawd, m-nitrobenzene sulfonyl chloride yuav tsum tau muab khaws cia kom zoo, kom deb ntawm qhov hluav taws kub thiab oxidants, thiab tsis txhob sib cuag nrog cov khoom siv hluav taws xob. Nyob rau hauv qhov xwm txheej ntawm mishandling los yog kev huam yuaj, nrhiav kev kho mob tam sim ntawd thiab coj lub compound cov ntaub ntawv kev nyab xeeb daim ntawv mus rau lub tsev kho mob.
