Isingeniso

I-Solvent Yellow 93, eyaziwa nangokuthi i-yellow G encibilikisiwe, ingudayi we-organic solvent. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

I-Solvent Yellow 93 iyicrystalline ephuzi ukuya kokuphuzi okusawolintshi, encibilika kuzincibilikisi zemvelo ezifana ne-ethanol ne-methylene chloride. Inokuncibilika okuphansi emanzini futhi ayincibiliki ezincibilikisini eziningi ezingaphili.

 

Sebenzisa:

I-Solvent Yellow 93 isetshenziswa kakhulu ezimbonini ezinjengodayi, oyinki, amapulasitiki, okokunamathela nezinamatheliso. Iyakwazi ukunikeza imikhiqizo nge-hue ephuzi ekhanyayo futhi ecacile futhi inokuqina okuhle nokuzinza kokukhanya.

 

Indlela:

I-Solvent Yellow 93 ivamise ukuhlanganiswa ngochungechunge lokusabela kwamakhemikhali. Indlela evamile yokulungiselela iwukusabela kokuhlangana kwe-aniline kanye ne-p-cresol, bese kuthi ngama-amides noma ama-ketones njengama-intermediate, ukusabela okwengeziwe kwe-acylation kuyenziwa ukuze ekugcineni kutholwe okuphuzi okuncibilikayo 93.

 

Ulwazi Lokuphepha:

I-solvent yellow 93 inobuthi obuthile, futhi kufanele kuqashelwe ukugwema ukuthintana okuqondile kwesikhumba kanye nokuhogela lapho uthintana. Gqoka amagilavu ​​okuzivikela kanye nemaski lapho uwasebenzisa, futhi ugcine umoya omuhle.

Gwema ukuthintana nama-oxidizing aqinile nama-acids ukuze uvimbele ukusabela okuyingozi.

Lapho ugcina, i-solvent yellow 93 kufanele igcinwe endaweni epholile, eyomile futhi enomoya omuhle, kude nomlilo kanye nokubasa.
