Isingeniso

I-Sudan yellow iyinhlanganisela yemvelo enegama lekhemikhali elithi Sudan I. Okulandelayo yisingeniso semvelo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-Sudan Yellow:

 

Ikhwalithi:

I-Sudan yellow iyimpushana yekristalu ewolintshi-ophuzi ukuya kokubomvu ngokubomvu ene-flavour ekhethekile yama-strawberry. Iyancibilika ku-ethanol, i-methylene chloride ne-phenol futhi ayincibiliki emanzini. I-Sudan yellow iqinile ekukhanyeni nasekushiseni, kodwa ibola kalula ngaphansi kwezimo ze-alkaline.

 

Ukusetshenziswa: Ingasetshenziswa futhi embonini kadayi nopende, kanye nebala le-microscope ekuhlolweni kwebhayoloji.

 

Indlela:

I-Sudan yellow ingalungiswa ngokusabela kwama-amine anephunga elimnandi njenge-aniline ne-benzidine ene-aniline methyl ketone. Ekuphenduleni, i-amine enephunga elimnandi ne-aniline methyl ketone ibhekana nokushintshana kwe-amine phambi kwe-sodium hydroxide ukwenza iSudan ibe phuzi.

 

Ulwazi Lokuphepha: Ukudla isikhathi eside noma ngokweqile kweSudan yellow kungase kudale izingozi ezithile zempilo kubantu. Ukusetshenziswa kweSudan yellow kudinga ukulawulwa okuqinile komthamo kanye nokuhambisana nemithetho nezindinganiso ezifanele. Ngaphezu kwalokho, i-Sudan yellow kufanele futhi igweme ukuthintana nesikhumba noma ukuhogela uthuli lwayo, okungabangela ukungezwani komzimba noma ukucasuka kokuphefumula.
