Mawu Oyamba
Ndi organic pawiri ndi chilinganizo C7H8N2O4S. Ndi woyera crystalline ufa ndi ofooka acidity. Zotsatirazi ndizofotokozera za katundu, ntchito, kukonzekera ndi chitetezo cha pawiri:
Chilengedwe:
-Maonekedwe: ufa woyera wa crystalline
-Kulemera kwa maselo: 216.21g / mol
-malo osungunuka: 168-170 ℃
-Kusungunuka: Kusungunuka pang'ono m'madzi, kosavuta kusungunuka mu zosungunulira za organic monga ethanol ndi acetone
- asidi ndi zamchere: asidi ofooka
Gwiritsani ntchito:
-Imagwiritsidwa ntchito makamaka mu organic synthesis ngati reagent yofunika komanso yapakatikati.
-Itha kugwiritsidwa ntchito pokonzekera mankhwala monga mankhwala, utoto ndi zinthu za polima.
Njira Yokonzekera:
Itha kupangidwa ndi njira zotsatirazi: br>1. Choyamba, pansi pamikhalidwe yoyenera, methyl bromide ndi p-nitrobenzene sulfonamide amapangidwa kupanga methyl ester.
2. Kenako, methyl ester imayendetsedwa ndi njira ya alkaline kuti ipeze mchere.
Zambiri Zachitetezo:
-ziyenera kusungidwa pamalo owuma, opanda mpweya wabwino, komanso kupewa kuwala kwa dzuwa.
-Pantchito, pewani kukhudzana ndi khungu ndi maso. Ngati zapezeka, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupita kuchipatala.
-Valani zida zodzitetezera zoyenera monga magolovesi, magalasi oteteza chitetezo komanso zovala zodzitchinjiriza pogwira ntchito.
-Osasakaniza mankhwalawa ndi ma oxidants amphamvu komanso ma acid amphamvu, chifukwa angayambitse zoopsa.
-Musanagwiritse ntchito kapena kugwiritsira ntchito pawiri, malangizo achitetezo operekedwa ndi wogulitsa awerengedwe mosamala.
