ʻO ka Disperse Yellow 241 he mea pena i hoʻohana nui ʻia no ka hoʻoluli ʻana i nā fibers, ʻoi aku ka nui o nā fiber synthetic.

ʻO ke ʻano hana o Disperse Yellow 241 ka mea maʻamau i kēia mau ʻanuʻu:

1. Hoʻomākaukau i nā mea hoʻomaka: E like me ke ʻano a me ke ala synthesis o ka dispersed yellow 241, ua synthesized nā mea hoʻomaka e ka hopena kemika. Hiki i kēia mau mea hoʻomaka ke komo i ka aniline, amino acids, etc.

2. Hoʻohui ʻia: Hoʻohui ʻia nā mea hoʻomaka no ka synthesis e ka pane ʻana me nā pūhui ʻē aʻe. ʻO kēia kaʻina hana maʻamau e pili ana i nā hopena synthesis kemika, e like me ka amidation, acetylation, a me nā mea ʻē aʻe.

3. Crystallization a me ka hoʻomaʻemaʻe: Aia ka huahana synthesized ma ke ʻano o kahi hopena a pono e hoʻoheheʻe ʻia a hoʻomaʻemaʻe ʻia e hoʻomaikaʻi i ka maʻemaʻe. ʻO kēia kaʻina hana maʻamau e pili ana i ka hoʻomalu ʻana i nā mea e like me ka wela, ke koho ʻana i ka solvent, a me nā mea ʻē aʻe, i mea e crystallize ai ka huahana a wehe i nā haumia.

4. Ka maloʻo a me ka ʻoki ʻana: Pono e hoʻomaloʻo ʻia ka huahana i hoʻomaʻemaʻe ʻia e loaʻa ka huahana melemele 241 i makemake ʻia. Hiki ke hoʻokō ʻia kēia ʻanuʻu ma ka hoʻomaloʻo ʻana i ka huahana ma nā haʻahaʻa haʻahaʻa a me ka ʻūhā, a me ka ʻoki ʻana iā ia me ka hoʻohana ʻana i nā mea hana kūpono e loaʻa ai ka nui o nā mea i makemake ʻia a me ka morphology.

5. Ka ho'āʻo a me ka nānāʻana: Pono e hoʻokō i ka nānāʻana i ka maikaʻi a me ka nānāʻana i ka melemele 241 i hoʻopuehuʻia i loaʻa mai ka hanaʻana e hōʻoia i ka maikaʻi o ka huahana i nā koi. ʻO nā ʻano hana ʻike maʻamau e pili ana i ka spectroscopy infrared, nuclear magnetic resonance, etc.
