Intshayelelo

I-Solvent Yellow 93, ekwaziwa njenge-yellow G enyityilisiweyo, yidayi enyibilikayo enyibilikayo. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:

 

Umgangatho:

I-Solvent Yellow 93 yikristale etyheli ukuya kwe-orenji-tyheli, enyibilikayo kwizinyibilikisi zendalo ezifana ne-ethanol kunye ne-methylene chloride. Inonyibiliko oluphantsi kakhulu emanzini kwaye ayinyibiliki kwizinyibilikisi ezininzi ezingaphiliyo.

 

Sebenzisa:

I-Solvent Yellow 93 isetyenziswa kakhulu kwimizi-mveliso efana nedayi, ii-inki, iiplastiki, izinto zokuhombisa kunye nezinto zokuncamathelisa. Iyakwazi ukubonelela ngeemveliso ezinombala ophuzi oqaqambileyo kunye ocacileyo kwaye unokuqina okulungileyo kunye nokuzinza kokukhanya.

 

Indlela:

I-Solvent Yellow 93 idla ngokudityaniswa ngothotho lokusabela kweekhemikhali. Indlela eqhelekileyo yokulungiselela kukudibana kwe-aniline kunye ne-p-cresol, kwaye emva koko ngee-amides okanye ii-ketones njengeziphakathi, ukusabela okungaphezulu kwe-acylation kuyenziwa ukuze ekugqibeleni kufumaneke i-solvent 93.

 

Ulwazi ngoKhuseleko:

I-solvent yellow 93 inetyhefu ethile, kwaye kufuneka ithathelwe ingqalelo ukunqanda ukudibana ngokuthe ngqo kwesikhumba kunye nokuphefumla xa udibana. Nxiba iiglavu zokukhusela kunye nemaski xa uzisebenzisa, kwaye ugcine umoya opholileyo.

Kuphephe ukudibana nee-oxidizing agents ezinamandla kunye ne-acids ukukhusela ukuphendula okuyingozi.

Xa ugcina, i-solvent yellow 93 kufuneka igcinwe kwindawo epholileyo, eyomileyo kunye nengena umoya, kude nomlilo kunye nokutshisa.
