Folasaga
4-nitrobenzenesulfonic acid (tetranitrobenzenesulfonic acid) o se mea faʻapipiʻi. O lo'o ta'ua i lalo se fa'amatalaga i nisi o meatotino, fa'aoga, metotia o sauniuniga ma fa'amatalaga saogalemu o le 4-nitrobenzene sulfonic acid:
Tulaga lelei:
1. Fa'aaliga: 4-nitrobenzene sulfonic acid o se tioata amorphous samasama samasama po'o le pauta malo.
2. Solubility: 4-nitrobenzene sulfonic acid e solu i le vai, ava malosi ma ether solvents, ma e le mafai ona faʻaaogaina i le tele o solvents organic.
3. Faʻamautu: E faʻamautu i le vevela o le potu, ae o le a pa pe a faʻafeiloaʻi faʻapogai faʻapogai, vevela maualuga ma oxidants malosi.
Fa'aaogā:
1. I le avea ai o se mea mataʻutia mo mea pāpā: 4-nitrobenzene sulfonic acid e mafai ona faʻaaogaina e avea o se tasi o mea mataʻutia mo mea pāpā (e pei o le TNT).
2. Faʻasologa o vailaʻau: E mafai ona faʻaaogaina e avea o se reagent nitrosylation i le faʻaogaina o meaola.
3. Alamanuia vali: I totonu o le alamanuia vali, 4-nitrobenzene sulfonic acid e mafai ona faʻaaogaina e avea o se mea faʻapipiʻi gaogao mo vali.
Metotia:
4-Nitrobenzene sulfonic acid e masani ona saunia e ala i le tali atu o le nitrobenzene sulfonyl chloride (C6H4 (NO2) SO2Cl) ma le vai poʻo le alkali.
Fa'amatalaga Saogalemu:
1. 4-nitrobenzene sulfonic acid e pa ma e tatau ona teuina ma faʻaoga i le matuaʻi tusa ai ma le saogalemu o taualumaga faʻagaioiga.
2. O le aafia i le 4-nitrobenzene sulfonic acid e mafai ona mafua ai le ita o le paʻu ma mata, ma e tatau ona faia ni puipuiga pe a manaʻomia.
3. Pe a tagofia le 4-nitrobenzene sulfonic acid, faʻafesoʻotaʻi ma mea e mu e tatau ona aloese mai le faʻalavelave afi poʻo le pa.
4. Lafoaia o otaota: otaota 4-nitrobenzene sulfonic acid e tatau ona lafoai e tusa ai ma tulafono faatonutonu a le lotoifale, ma e matua faasaina le lafoai i vaipuna po o le siosiomaga.
