Mawu Oyamba

Aminobenzene sulfonic acid, yemwenso amadziwika kuti sulfamine phenol, ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chitetezo cha p-aminobenzene sulfonic acid:

 

Ubwino:

Aminobenzenesulfonic acid ndi ufa wa crystalline woyera womwe umakhala wopanda fungo komanso wosungunuka m'madzi ndi ethanol.

 

Ntchito: Itha kugwiritsidwanso ntchito popanga utoto wina ndi mankhwala.

 

Njira:

Aminobenzenesulfonic acid akhoza kupezedwa ndi zimene benzenesulfonyl kolorayidi ndi aniline. Choyamba, aniline ndi alkali amafupikitsidwa kupanga m-aminobenzene sulfonic acid, ndiyeno aminobenzene sulfonic acid imapezeka ndi acylation reaction.

 

Zambiri Zachitetezo:

Kuwonjezera pa zotsatira zake zokwiyitsa pa maso, khungu, ndi kupuma, aminobenzene sulfonic acid sinafotokozedwe momveka bwino kuti ndi yapoizoni kapena yoopsa. Mukamagwiritsa ntchito kapena kugwira aminobenzene sulfonic acid, sungani mpweya wabwino, pewani kukhudzana ndi maso ndi khungu, ndipo valani zida zodzitetezera ngati kuli kofunikira. Ngati mumeza kapena kukhudza mwangozi, pitani kuchipatala mwamsanga. Posunga ndi kusunga, iyenera kusungidwa pamalo owuma, ozizira, kutali ndi moto ndi zinthu zina zoyaka.
