Taw qhia
4-nitrobenzenesulfonic acid (tetranitrobenzenesulfonic acid) yog cov organic compound. Cov hauv qab no yog kev qhia txog qee yam ntawm cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 4-nitrobenzene sulfonic acid:
Zoo:
1. Cov tsos mob: 4-nitrobenzene sulfonic acid yog lub teeb daj amorphous siv lead ua los yog hmoov hmoov.
2. Solubility: 4-nitrobenzene sulfonic acid yog soluble nyob rau hauv dej, cawv thiab ether solvents, thiab insoluble nyob rau hauv feem ntau organic solvents.
3. Kev ruaj ntseg: Nws yog qhov ruaj khov ntawm chav tsev kub, tab sis nws yuav tawg thaum nws ntsib qhov hluav taws kub, qhov kub thiab txias thiab muaj zog oxidants.
Siv:
1. Raws li cov khoom siv raw rau cov khoom tawg: 4-nitrobenzene sulfonic acid tuaj yeem siv los ua ib qho ntawm cov khoom siv raw rau cov khoom tawg (xws li TNT).
2. Chemical synthesis: Nws tuaj yeem siv los ua nitrosylation reagent hauv organic synthesis.
3. Kev lag luam Dye: Hauv kev lag luam dyeing, 4-nitrobenzene sulfonic acid tuaj yeem siv los ua cov khoom siv nruab nrab rau dyes.
Txoj kev:
4-Nitrobenzene sulfonic acid feem ntau yog npaj los ntawm cov tshuaj tiv thaiv ntawm nitrobenzene sulfonyl chloride (C6H4 (NO2) SO2Cl) nrog dej los yog alkali.
Cov ntaub ntawv kev nyab xeeb:
1. 4-nitrobenzene sulfonic acid yog tawg thiab yuav tsum tau muab khaws cia thiab siv nruj raws li cov txheej txheem kev nyab xeeb.
2. Kev raug rau 4-nitrobenzene sulfonic acid tuaj yeem ua rau tawv nqaij thiab qhov muag, thiab kev tiv thaiv yuav tsum tau ua yog tias tsim nyog.
3. Thaum tuav 4-nitrobenzene sulfonic acid, kev sib cuag nrog cov khoom siv hluav taws xob yuav tsum raug zam kom tsis txhob muaj hluav taws kub lossis tawg.
4. Kev pov tseg pov tseg: Cov khib nyiab 4-nitrobenzene sulfonic acid yuav tsum muab pov tseg raws li cov kev cai hauv zos, thiab nws yog txwv tsis pub muab pov tseg rau hauv dej los yog ib puag ncig.
