Isingeniso

I-1,3-Difluoro-2-propanol, eyaziwa nangokuthi i-DFP, iyinhlanganisela yezinto eziphilayo.

 

Izakhiwo: I-DFP iwuketshezi olungenambala olunephunga elikhethekile.

 

Ukusetshenziswa: I-DFP inezinhlelo zokusebenza ezihlukahlukene. I-DFP iphinde isetshenziswe njenge-catalyst kanye ne-surfactant ku-organic synthesis.

 

Indlela yokulungiselela: I-DFP ivame ukulungiswa ngokusabela i-1,1,1,3,3,3-hexafluoro-2-propanol nge-hydrogen chloride, bese ikhiqiza i-DFP nge-hydrating fluoride.

 

Ulwazi lokuphepha: I-DFP iyinhlanganisela yemvelo enobungozi obuthile. Kungabangela ukucasuka esikhumbeni nasemehlweni, futhi kunobuthi futhi kudlangile. Lapho usebenzisa noma uphatha i-DFP, izinto zokuzivikela ezifanele njengezingilazi zokuphepha, amagilavu, nezingubo zokuzivikela zidinga ukugqokwa. Kudingeka ukuthi kusetshenzwe endaweni engenawo umoya ukuze kugwenywe ukuhogela umhwamuko we-DFP. Uma udalula noma uhogela i-DFP ngephutha, funa usizo lwezokwelapha.
