Disperse Yellow 241 CAS 83249-52-9 suma

Disperse Yellow 241 idhayi rekugadzira rinonyanya kushandiswa kudhayi faibha, kunyanya mafibhi ekugadzira.

Iyo nzira yekugadzira yeDisperse Yellow 241 kazhinji inosanganisira anotevera matanho:

1. Kugadzirira kwezvinhu zvekutanga: Zvinoenderana nechimiro uye nzira yekubatanidza yero yakapararira 241, zvinhu zvekutanga zvinogadzirwa nemakemikari kuita. Izvi zvekutanga zvekutanga zvinogona kusanganisira aniline, amino acids, nezvimwe.

2. Rection synthesis: Zvishandiso zvekutanga zve synthesis zvinogadzirwa nekuita nemamwe makomisheni anodiwa. Danho iri rinowanzo sanganisira kuita kwemakemikari, senge amidation, acetylation, nezvimwewo. Izvi zvinogadzira zvigadzirwa zvepakati zvinoda kugadziriswa uye kurapwa kuti uwane chaunoda magumo chigadzirwa.

3. Crystallization uye kucheneswa: Chigadzirwa chakagadzirwa chinowanzovapo muchimiro chekugadzirisa uye chinoda kucheneswa uye kucheneswa kuvandudza kuchena. Iyi nhanho inowanzo sanganisira kudzora zvinhu senge tembiricha, sarudzo yesolvent, nezvimwe, kuitira kupenya chigadzirwa uye kubvisa tsvina.

4. Kuomesa nekupwanya: Chigadzirwa chakacheneswa chinoda kuomeswa nekupushwa kuti chiwane chinodiwa chakaparadzirwa yero 241 chigadzirwa. Iyi nhanho inogona kuwanikwa nekuomesa chigadzirwa pane yakaderera tembiricha uye vacuum, uye nekuchipwanya uchishandisa yakakodzera michina kuti uwane inodiwa saizi uye morphology.

5. Kuedza uye kuongorora: Izvo zvinodikanwa kuita ongororo yemhando uye ongororo pane yakapararira yero 241 yakawanikwa kubva mukugadzirwa kuti ive nechokwadi chekuti chigadzirwa chemhando inosangana nezvinodiwa. Nzira dzinowanzo shandiswa dzekuona dzinosanganisira infrared spectroscopy, nuclear magnetic resonance, nezvimwe.
