Isingeniso

I-2-Isopropoxyethanol, eyaziwa nangokuthi isopropyl ether ethanol. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala.

- I-Solubility: Incibilika emanzini, otshwaleni nasezincibilikisini ze-ether.

 

Sebenzisa:

- Ukusetshenziswa kwezimboni: I-2-isopropoxyethanol ingasetshenziswa njenge-ejenti yokuhlanza, okokuhlanza kanye ne-solvent, futhi isetshenziswa kabanzi embonini yamakhemikhali, yokunyathelisa, yokuhlanganisa kanye ne-electronics.

 

Indlela:

Izindlela zokulungiselela i-2-isopropoxyethanol ikakhulukazi zimi kanje:

- Ukusabela kwe-Ethanol ne-isopropyl ether: I-Ethanol isabela nge-isopropyl ether ezingeni lokushisa elifanele nezimo zokusabela ukukhiqiza i-2-isopropoxyethanol.

- Ukusabela kwe-isopropanol nge-ethylene glycol: I-Isopropanol isabela nge-ethylene glycol ekushiseni okufanelekile nezimo zokusabela ukukhiqiza i-2-isopropoxyethanol.

 

Ulwazi Lokuphepha:

- I-2-Isopropoxyethanol iyacasula kancane futhi iyashintshashintsha, futhi ingabangela ukucasuka kwamehlo nesikhumba lapho ithintwa, ngakho-ke ukuthintana okuqondile kufanele kugwenywe.

- Izinyathelo ezifanele zokuzivikela ezinjengokugqoka amagilavu ​​nezibuko ezimelana namakhemikhali kufanele zithathwe ngesikhathi sokuphatha nokusebenzisa.

- Kufanele isetshenziswe endaweni enomoya omuhle ukuze kugwenywe ukuhogela imfucumfucu futhi kuvimbele ukuthungela nokwakheka kukagesi omile.

- Ngesikhathi sokugcina nokuthutha, ukuthintana nama-oxidants nama-acids aqinile kufanele kugwenywe, futhi ukudlidliza okukhulu kanye nezinga lokushisa eliphakeme kakhulu kufanele kugwenywe ukuze kuvinjelwe izingozi.

 

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
