Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-Disperse Yellow 241 CAS 83249-52-9 yethula

I-Disperse Yellow 241 wudayi wokwenziwa osetshenziswa kakhulu ukudaya imicu, ikakhulukazi imicu yokwenziwa.

Indlela yokukhiqiza ye-Disperse Yellow 241 ngokuvamile ihlanganisa lezi zinyathelo ezilandelayo:

1. Ukulungiswa kwezinto zokuqala: Ngokusho kwesakhiwo kanye nomzila wokuhlanganisa we-yellow 241 ehlakaziwe, izinto zokuqala zihlanganiswa nokusabela kwamakhemikhali. Lezi zinto zokuqala zingabandakanya i-aniline, ama-amino acid, njll.

2. Ukuhlanganiswa kokusabela: Izinto zokuqala zokuhlanganiswa zihlanganiswa ngokusabela nezinye izinhlanganisela ezidingekayo. Lesi sinyathelo ngokuvamile sibandakanya ukusabela kokuhlanganiswa kwamakhemikhali, okufana ne-amidation, i-acetylation, njll. Lokhu kusabela kukhiqiza imikhiqizo ephakathi nendawo edinga ukufakwa isimo futhi ilashwe ukuze kutholwe umkhiqizo wokugcina ofunekayo.

3. I-Crystallization kanye nokuhlanzwa: Umkhiqizo ohlanganisiwe uvame ukuba khona ngesimo sesixazululo futhi udinga ukufakwa amakristalu nokuhlanzwa ukuze kuthuthukiswe ubumsulwa. Lesi sinyathelo ngokuvamile sihilela ukulawula izici ezifana nezinga lokushisa, ukukhethwa kwezincibilikisi, njll., ukuze kukhanye umkhiqizo futhi kukhishwe ukungcola.

4. Ukomiswa kanye nokuchotshozwa: Umkhiqizo ohlanziwe udinga ukomiswa futhi ugaywe ukuze kutholwe umkhiqizo ophuzi ohlakaziwe ohlakaziwe we-241. Lesi sinyathelo singafinyelelwa ngokomisa umkhiqizo emazingeni okushisa aphansi kanye ne-vacuum, futhi ukuwuchoboza kusetshenziswa okokusebenza okufanelekile ukuze kutholwe usayizi wezinhlayiyana oyifunayo kanye ne-morphology.

5. Ukuhlola nokuhlaziya: Kuyadingeka ukwenza ukuhlolwa kwekhwalithi nokuhlaziya kokuphuzi okuhlakaziwe okungu-241 okutholwe ekukhiqizweni ukuze kuqinisekiswe ukuthi ikhwalithi yomkhiqizo iyahlangabezana nezidingo. Izindlela zokuhlonza ezivame ukusetshenziswa zifaka i-infrared spectroscopy, i-nuclear magnetic resonance, njll.
