Balalitsa Yellow 241 CAS 83249-52-9 yambitsani

Disperse Yellow 241 ndi utoto wopangidwa womwe umagwiritsidwa ntchito kwambiri popaka ulusi, makamaka ulusi wopangira.

Njira yopangira Disperse Yellow 241 nthawi zambiri imakhala ndi izi:

1. Kukonzekera kwa zida zoyambira: Malinga ndi kapangidwe kake ndi kaphatikizidwe ka chikasu chomwazika 241, zida zoyambira zimapangidwira ndi machitidwe amankhwala. Zida zoyambira izi zingaphatikizepo aniline, amino acid, etc.

2. Kaphatikizidwe kazinthu: Zida zoyambira za kaphatikizidwe zimapangidwira ndi zomwe zimafunikira. Izi nthawi zambiri zimakhudzana ndi kaphatikizidwe ka mankhwala, monga amidation, acetylation, ndi zina zotere. Izi zimatulutsa zinthu zapakatikati zomwe zimafunikira kusinthidwa ndikuthandizidwa kuti mupeze zomwe mukufuna.

3. Crystallization ndi kuyeretsedwa: The apanga mankhwala nthawi zambiri alipo mu mawonekedwe a yankho ndipo ayenera crystallized ndi kuyeretsedwa kusintha chiyero. Gawoli nthawi zambiri limakhudza kuwongolera zinthu monga kutentha, kusankha zosungunulira, ndi zina zambiri, kuti muunikire zinthuzo ndikuchotsa zonyansa.

4. Kuyanika ndi kuphwanya: Chotsukidwacho chiyenera kuumitsidwa ndi kupukutidwa kuti tipeze chinthu chomwe mukufuna chomwazika chachikasu 241. Sitepe chingapezeke mwa kuyanika mankhwala pa otsika kutentha ndi vakuyumu, ndi kuphwanya izo ntchito zipangizo zoyenera kupeza kufunika tinthu kukula ndi kapangidwe kake.

5. Kuyesa ndi kusanthula: Ndikofunikira kuyang'anira ndikuwunika kwamtundu wachikasu 241 womwazika wopezedwa kuchokera kukupanga kuti muwonetsetse kuti mtundu wa malondawo ukukwaniritsa zofunikira. Njira zodziwira zomwe zimagwiritsidwa ntchito nthawi zambiri ndi monga infrared spectroscopy, nyukiliya maginito resonance, etc.
