Intshayelelo

I-Solvent Yellow 157 yidayi ephilayo, ekwabizwa ngokuba yi-Direct Yellow 12. Igama layo lekhemikhali ngu-3-[(2-Chlorophenyl)azo] -4-hydroxy-N,N-bis(2-hydroxyethyl)aniline, kunye ne-chemical formula. yi C19H20ClN3O3. Ngumgubo otyheli oqinileyo.

 

I-Solvent Yellow 157 isetyenziswa kakhulu njengedayi esekwe kwi-Solvent, enokuthi inyibilikiswe kwizinyibilikisi zendalo, ezifana ne-acetone, utywala kunye nezinyibilikisi ze-ether. Ingasetyenziselwa ukudaya iimveliso ezifana neeplastiki, iintlaka, iipeyinti, iingubo, iifayibha nee-inki. Ingasetyenziselwa ukudaya amakhandlela kunye neetreyi zewax.

 

Indlela yokulungiselela i-Solvent Yellow 157 idla ngokuphendula i-2-chloroaniline kunye ne-2-hydroxyethylaniline, kunye nokwenza ukusabela kokudibanisa phantsi kweemeko ezifanelekileyo. Imveliso yokusabela yahluzwa yaza yahluzwa ukunika iSolvent etyheli esulungekileyo eyi-157.

 

Ngolwazi lokhuseleko, iSolvent Yellow 157 inokuba yingozi. Inokubangela ukucaphuka kwamehlo, ulusu kunye nokuphefumla, ngoko sebenzisa amanyathelo afanelekileyo okukhusela, njengokunxiba iiglavu zokhuselo kunye neendondo. Ukongeza, kuphephe ukuphefumla uthuli kwaye usebenze kwindawo engenamoya.
