Gwiritsani ntchito Itha kugwiritsidwa ntchito pamitundu yosiyanasiyana ya utomoni
Maphunziro a in vitro Sudan III imasintha mtundu wake kuchokera ku lalanje kupita ku buluu motsutsana ndi kachulukidwe kakang'ono ka sulfuric acid, ndipo yankho la acetonitrile la Sudan III ndiloyenera kwambiri kuwona kusintha kwamitundu. Kafukufuku wowoneka bwino wa H-NMR ndi UV-Vis akuwonetsa kuti njira yosinthira mitundu ya Sudan III motsutsana ndi sulfuric acid ndi chifukwa cha kupangika kwa utoto ndi sulfuric acid.

Mawu Oyamba

Benzoazobenzoazo-2-naphthol amagwiritsidwa ntchito makamaka ngati utoto m'mafakitale monga nsalu, inki ndi mapulasitiki. Ikhoza kugwiritsidwa ntchito popaka zida za ulusi monga thonje, nsalu, ubweya, ndi zina zotero. Kukhazikika kwa mtundu wake ndi kwabwino komanso kosavuta kutha, kotero kumagwiritsidwa ntchito kwambiri m'munda wa nsalu.

 

Njira yokonzekera benzoazobenzobenzo-azo-2-naphthol nthawi zambiri imapangidwa ndi azo reaction. Aniline amayamba kuchitapo kanthu ndi asidi wa nitric kupanga nitroaniline, kenako amachitira ndi naphtholl kupanga mankhwala omwe akufuna, benzoazobenzo-azo-2-naphthol.

 

Zambiri zokhudzana ndi chitetezo cha benzoazobenzenezo-2-naphthol, ndi chinthu choyaka moto ndipo chimayenera kusungidwa pamalo ozizira, opanda mpweya wabwino, kutali ndi magwero amoto komanso kutentha kwambiri. Zida zodzitetezera zoyenera monga magolovesi a labu, magalasi otetezera chitetezo, ndi malaya a labu ziyenera kuvalidwa panthawi yogwira ntchito. Popeza ndi mankhwala, njira zoyendetsera chitetezo ndi njira zotayira zinyalala ziyenera kutsatiridwa.
