Intshayelelo

I-Solvent Yellow 18 sisinyibilikisi esiphilayo esinegama lekhemikhali ye-2-chloro-1,3,2-dibenzothiophene.

 

I-Solvent Yellow 18 inezi mpawu zilandelayo:

1. Imbonakalo: etyheli yikristale engumgubo eqinileyo;

4. Ukunyibilika: Inyibilika kwi-polar organic solvents, njenge-ethanol, ii-ethers kunye ne-chlorinated hydrocarbons.

 

Usetyenziso oluphambili lwe-solvent yellow 18:

1. Njengedayi ephakathi: i-solvent yellow 18 ingasetyenziselwa ukuhlanganiswa kwedayi, kwaye idlala indima ebalulekileyo ekudayeni amalaphu, iphepha okanye iimveliso zeplastiki;

2. Njenge-solvent: Ine-solubility efanelekileyo kwaye inokusetyenziswa njenge-solvent kwi-organic synthesis reactions.

 

Ukulungiselela indlela ye-solvent yellow 18:

I-solvent yellow 18 inokubunjwa ngokusabela kwe-benzothiophene kunye ne-chloroacetyl chloride, kwaye ifunyenwe yi-catalytic action ye-cuprous chloride kunye ne-iridium carbonate.

 

Ulwazi ngoKhuseleko lweSolvent etyheli 18:

1. I-solvent yellow 18 inokucaphuka okuthile kunye netyhefu, enokubangela ukucaphuka kunye nokukhathazeka xa udibana nolusu kunye nokuphefumla;

2. Kufuneka kuthathelwe ingqalelo ukuthintela ukudibana nolusu kunye namehlo xa usebenzisa, kwaye uqinisekise ukuba utyando lwenziwa kwindawo engena umoya;

3. Kwimeko yokudibanisa okanye ukungeniswa ngengozi, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango ngexesha;

4. Xa ugcina, kufuneka ivalwe kwaye igcinwe kwindawo epholileyo, eyomileyo ukuze ugweme ukudibanisa ne-oxidants eqinile kunye ne-acids eqinile.
