Isingeniso

I-Propanol, eyaziwa nangokuthi isopropanol, iyi-solvent ephilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-propanol:

 

Ikhwalithi:

- I-Propanol iwuketshezi olungenambala olunephunga eliwuphawu lotshwala.

- Ingancibilikisa amanzi, ama-ether, ama-ketone, nezinto eziningi eziphilayo.

 

Sebenzisa:

- I-Propanol isetshenziswa kabanzi embonini njenge-solvent ekwenzeni amapende, ama-coatings, ama-ejenti okuhlanza, odayi, nezingulube.

 

Indlela:

- I-Propanol ingalungiswa nge-hydrogenation ye-methane hydrates.

- Enye indlela evame ukusetshenziswa yokulungiselela itholakala nge-hydrogenation eqondile ye-propylene namanzi.

 

Ulwazi Lokuphepha:

- I-Propanol iyavutha futhi kufanele igcinwe kude namalangabi avulekile kanye namazinga okushisa aphezulu.

- Lapho uphatha i-propanol, gqoka izinto zokuzivikela ezifanele njengamagilavu, izibuko, nezingubo zokuzivikela.
