Intshayelelo

Ipropanol, ekwabizwa ngokuba yi-isopropanol, sisinyibilikisi sezinto eziphilayo. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwepropanol:

 

Umgangatho:

- I-Propanol ilulwelo olungenambala kunye nevumba elibonakalayo lotywala.

- Inokunyibilikisa amanzi, ii-ethers, iiketones, kunye nezinto ezininzi eziphilayo.

 

Sebenzisa:

- I-Propanol isetyenziswa ngokubanzi kwishishini njenge-solvent ekwenzeni iipeyinti, iingubo, ii-agent zokucoca, iidayi, kunye ne-pigments.

 

Indlela:

- Ipropanol inokulungiswa nge-hydrogenation ye-methane hydrates.

- Enye indlela yokulungiselela esetyenziswa ngokuqhelekileyo ifunyenwe nge-hydrogenation ngqo yepropylene kunye namanzi.

 

Ulwazi ngoKhuseleko:

- I-Propanol inokutsha kwaye kufuneka igcinwe kude namadangatye avulekileyo kunye namaqondo okushisa aphezulu.

- Xa uphethe ipropanol, nxiba izixhobo ezifanelekileyo zokukhusela ezinjengeeglavu, iiglasi, kunye nempahla yokukhusela.
