Intshayelelo

I-Solvent Yellow 44 ikwabizwa ngokuba yiSudan Yellow G kwikhemistri, kwaye ubume bayo bekhemikhali yichromate yeSudan Yellow G. Oku kulandelayo sisingeniso kubume bayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:

 

Umgangatho:

- Imbonakalo: Solvent Yellow 44 yi crystalline umgubo ukusuka orenji-tyheli ukuya kubomvu-tyheli.

- Ukunyibilika: ukunyibilika emanzini, methanol, ethanol, okunganyibilikiyo kwi-ether, benzene kunye nezinye izinyibilikisi eziphilayo.

 

Sebenzisa:

- Idayi zeMichiza: i-solvent yellow 44 ingasetyenziswa njengedayi kwiidayi kunye nokuleyibhela ii-reagents.

 

Indlela:

I-44 enyibilikayo emthubi ilungiswa ikakhulu ngokusabela kwekhromate yesodium kunye neSudan emthubi G kwisisombululo esimanzi.

 

Ulwazi ngoKhuseleko:

- I-Solvent Yellow 44 yidayi yeekhemikhali kwaye kufuneka iphathwe ngononophelo ukuphepha ukuphefumla uthuli okanye ukudibanisa nolusu, amehlo, njl.

- Nxiba izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu, iiglasi, kunye nempahla yokuzikhusela ngexesha lokusetyenziswa.

- Kwimeko yokuphefumla okanye ukudibana kwesikhumba, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune uncedo lwezonyango.

- Ngexesha lokugcinwa, i-solvent yellow 44 kufuneka ibekwe kwindawo eyomileyo, epholileyo, indawo engenamoya ukuze ugweme ukudibanisa nokutshisa, i-oxidants okanye ezinye izinto ezisebenzayo.

 

Ngokuqhelekileyo, ukusetyenziswa kwe-solvent yellow 44 kufuneka kuqhutywe ngokuhambelana neenkqubo zokusebenza ezikhuselekileyo kwaye ngokwendawo ethile yesicelo kunye neemfuno zokulawula.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
