Isingeniso

I-Solvent Yellow 157 idayi yemvelo, eyaziwa nangokuthi Ephuzi Eqondile 12. Igama layo lekhemikhali ngu-3-[(2-Chlorophenyl)azo] -4-hydroxy-N,N-bis(2-hydroxyethyl)aniline, kanye nefomula yamakhemikhali. Idatha ye-C19H20ClN3O3 Iwuphuphu oluphuzi oluqinile.

 

I-Solvent Yellow 157 isetshenziswa kakhulu njengodayi osuselwe ku-Solvent, ongancibilika kuzincibilikisi zemvelo, njenge-acetone, utshwala nezincibilikisi ze-ether. Ingasetshenziselwa ukudaya imikhiqizo efana nepulasitiki, ama-resin, amapende, okokunamathela, imicu noyinki. Ingase futhi isetshenziselwe ukudaya amakhandlela namathileyi we-wax.

 

Indlela yokulungiselela i-Solvent Yellow 157 ivamise ukusabela i-2-chloroaniline kanye ne-2-hydroxyethylaniline, kanye nokwenza ukusabela kokuhlanganisa ngaphansi kwezimo ezifanele. Umkhiqizo wokusabela uye wacwengwa futhi wahlungwa ukuze unikeze i-Solvent Yellow 157 ehlanzekile.

 

Ngolwazi lokuphepha, i-Solvent Yellow 157 ingaba yingozi. Kungase kubangele ukucasuka emehlweni, isikhumba kanye nokuhogela, ngakho sebenzisa izindlela zokuzivikela ezifanele, njengokugqoka amagilavu ​​okuzivikela kanye nezibuko. Ngaphezu kwalokho, gwema ukuhogela uthuli futhi usebenze endaweni engenawo umoya.
