Disperse Yellow 241 ke dae ea maiketsetso e sebelisoang haholo ho daea likhoele, haholo likhoele tsa maiketsetso.

Mokhoa oa tlhahiso ea Disperse Yellow 241 ka kakaretso o kenyelletsa mehato e latelang:

1. Tokisetso ea lisebelisoa tsa ho qala: Ho ea ka sebopeho le tsela ea motsoako oa mosehla o qhalakantsoeng oa 241, lisebelisoa tsa ho qala li entsoe ka lik'hemik'hale. Lisebelisoa tsena tsa ho qala li ka kenyelletsa aniline, amino acid, joalo-joalo.

2. Rection synthesis: Thepa ea ho qala ea ho kopanya e entsoe ka karabelo le metsoako e meng e hlokahalang. Mohato ona ka kakaretso o kenyelletsa ts'ebetso ea motsoako oa lik'hemik'hale, joalo ka amidation, acetylation, joalo-joalo. Lits'ebetso tsena li hlahisa lihlahisoa tse mahareng tse hlokang ho lokisoa le ho phekoloa ho fumana sehlahisoa se lakatsehang.

3. Crystallization le tlhoekiso: Sehlahisoa se entsoeng hangata se teng ka mokhoa oa tharollo 'me se hloka ho hloekisoa le ho hloekisoa ho ntlafatsa bohloeki. Mohato ona ka kakaretso o kenyelletsa ho laola lintlha tse kang mocheso, khetho ea solvent, joalo-joalo, e le ho khabisa sehlahisoa le ho tlosa litšila.

4. Ho omisa le ho silakanya: Sehlahisoa se hloekisitsoeng se hloka ho omisoa le ho siloa ho fumana sehlahisoa se lakatsehang sa mosehla 241. Mohato ona o ka finyelloa ka ho omisa sehlahisoa ka mocheso o tlase le vacuum, le ho se silakanya ka ho sebelisa lisebelisoa tse loketseng ho fumana boholo bo lakatsehang le morphology.

5. Teko le tlhahlobo: Hoa hlokahala ho etsa tlhahlobo ea boleng le tlhahlobo ho mosehla o hasantsoeng oa 241 o fumanoeng tlhahisong ho netefatsa hore boleng ba sehlahisoa bo fihlela litlhoko. Mekhoa e sebelisoang hangata ea ho lemoha e kenyelletsa spectroscopy ea infrared, nuclear magnetic resonance, joalo-joalo.
