Okuphuzi 18 CAS 6407-78-9

Isingeniso

I-Solvent Yellow 18 iyincibilikisi yemvelo enegama lamakhemikhali elithi 2-chloro-1,3,2-dibenzothiophene.

I-Solvent Yellow 18 inezindawo ezilandelayo:

1. Ukubukeka: i-yellow crystalline powdery okuqinile;

4. Ukunyibilika: Kuncibilika kuzincibilikisi zemvelo ezishisayo, njenge-ethanol, ama-ethers nama-hydrocarbon ane-chlorine.

Ukusetshenziswa okuyinhloko kwe-solvent yellow 18:

1. Njengodayi ophakathi nendawo: i-solvent yellow 18 ingasetshenziswa ekuhlanganiseni amadayi, futhi idlala indima ebalulekile ekudayeni izindwangu, iphepha noma imikhiqizo yepulasitiki;

2. Njenge-solvent: Ine-solubility enhle futhi ingasetshenziswa njenge-solvent ekuphenduleni kwe-organic synthesis.

Indlela yokulungiselela i-solvent yellow 18:

I-solvent yellow 18 ingakhiwa ukusabela kwe-benzothiophene nge-chloroacetyl chloride, bese itholwa isenzo esinamandla se-cuprous chloride ne-iridium carbonate.

Ulwazi Lokuphepha Lwe-Solvent Yellow 18:

1. I-solvent yellow 18 inokucasuka okuthile nobuthi, okungase kubangele ukucasuka nokungakhululeki lapho uthintana nesikhumba kanye nokuhogela;

2. Kufanele kuqashelwe ukuvimbela ukuthintana nesikhumba namehlo lapho usebenzisa, futhi uqinisekise ukuthi ukuhlinzwa kwenziwa endaweni enomoya omuhle;

3. Uma uthintana noma ungenwe ngephutha, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha kusenesikhathi;

4. Uma uyigcina, kufanele ivalwe futhi igcinwe endaweni epholile, eyomile ukuze kugwenywe ukuthintana nama-oxidants aqinile nama-asidi aqinile.
