Isingeniso

I-Pigment yellow 138, eyaziwa nangokuthi imbali eluhlaza okwesibhakabhaka, icilongo eliphuzi, igama lekhemikhali yi-2,4-dinitro-N-[4-(2-phenylethyl)phenyl]aniline. Okulandelayo yisingeniso kwezinye zezakhiwo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha lwe-Yellow 138:

 

Ikhwalithi:

- I-Yellow 138 iyimpushana ecwebezelayo ephuzi, encibilika kalula kuzincibilikisi zemvelo, njenge-methanol, i-ethanol, njll., futhi engancibiliki emanzini.

- Isakhiwo sayo samakhemikhali sinquma ukuthi sinokusebenza okuhle kwezithombe nokumelana nokushisa.

- I-Yellow 138 inokusimama okuhle ngaphansi kwezimo ezine-acidic, kodwa ijwayele ukushintsha umbala ngaphansi kwezimo ze-alkaline.

 

Sebenzisa:

- I-Yellow 138 isetshenziswa kakhulu njenge-organic pigment futhi isetshenziswa kakhulu kumapende, oyinki, amapulasitiki nezinye izimboni.

- Ngenxa yombala ophuzi ocacile kanye nokushesha kombala omuhle, iYellow 138 ivame ukusetshenziswa njengebala lombala emidwebeni kawoyela, umdwebo we-watercolor, umdwebo we-acrylic neminye imikhakha yobuciko.

 

Indlela:

- Indlela yokulungiselela ye-yellow 138 iyinkimbinkimbi kakhulu, futhi ngokuvamile itholakala ngokusabela kwe-oxidation nama-amino compounds.

- Indlela ethile yokulungiselela ingase ihlanganise ukusabela kwezinhlanganisela ze-nitroso ne-aniline ukuze kutholwe i-2,4-dinitro-N-[4-(2-phenylethyl)phenyl]imine, bese kuba ukusabela kwe-imine nge-hydroxide esiliva ukulungiselela i-Huang 138 .

 

Ulwazi Lokuphepha:

- Okuphuzi 138 ngokuvamile kubhekwa njengokuzinzile futhi kuphephe kakhulu ngaphansi kwezimo ezijwayelekile zokusetshenziswa.

- I-Yellow 138 ijwayele ukushintsha umbala ngaphansi kwezimo ze-alkaline, ngakho-ke ukuthintana nezinto ezine-alkaline kufanele kugwenywe.
