Intshayelelo

I-2-pentanone, eyaziwa ngokuba yi-pentanone, yi-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-2-pentaone:

Umgangatho:

- Ukubonakala: I-2-pentanone ilulwelo olungenambala kunye nephunga elikhethekileyo.

- Ukunyibilika: Inokunyibilika emanzini kwaye ikwaxubene nezinyibilikisi ezininzi eziphilayo.

- Ukutsha: I-2-pentanone lulwelo olunokutsha olunokubangela umlilo xa kukho ilangatye elivulekileyo okanye amaqondo obushushu aphezulu.

Sebenzisa:

- Ukusetyenziswa kwamashishini: I-2-pentaone isetyenziswe njenge-solvent kwimveliso yeengubo, ii-inki, i-adhesives, njl., njenge-diluent, i-agent yokucoca, kunye ne-reaction intermediate.

Indlela:

- I-2-pentanone ilungiswa ngokubanzi nge-oxidizing pentanol. Indlela eqhelekileyo kukusabela nge-pentanol nge-agent e-oxidizing efana ne-oxygen okanye i-hydrogen peroxide, kunye nokukhawuleza ukusabela nge-catalyst efana ne-potassium chromate okanye i-cerium oxide.

Ulwazi ngoKhuseleko:

- I-2-pentaone inokutsha kwaye kufuneka igcinwe kude namadangatye avulekileyo kunye namaqondo obushushu aphezulu.

-Nxiba iiglavu ezikhuselayo, iiglasi ezikhuselayo, kunye nesikhuselo sobuso esikhuselayo ukunqanda ukudibana namehlo, ulusu kunye nomphunga.

- Inkunkuma kufuneka ilahlwe ngokungqinelana nemithetho kunye nemimiselo yendawo, kwaye akufanele ilahlwe emanzini okanye kwindawo engqongileyo.

- Xa ugcina kwaye usebenzisa, nceda ulandele ngokungqongqo iinkqubo ezifanelekileyo zokusebenza kunye nezikhokelo zokuqinisekisa ukusetyenziswa nokugcinwa kwazo ngokufanelekileyo.
