Isingeniso

I-2-pentanone, eyaziwa nangokuthi i-pentanone, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2-pentanone:

Ikhwalithi:

- Ukubukeka: I-2-pentanone iwuketshezi olungenambala olunephunga elikhethekile.

- Ukunyibilika: Ingancibilika emanzini futhi iphinde ixubane nezinyibilikisi eziningi eziphilayo.

- Ukuvutha: I-2-pentaone iwuketshezi oluvuthayo olungadala umlilo uma kuba nelangabi elivulekile noma amazinga okushisa aphezulu.

Sebenzisa:

- Ukusetshenziswa kwezimboni: I-2-pentaone isetshenziswa njenge-solvent ekukhiqizeni okunamathelayo, oyinki, okunamathelayo, njll., njenge-diluent, i-ejenti yokuhlanza, kanye nokusabela okuphakathi.

Indlela:

- I-2-pentanone ngokuvamile ilungiswa nge-oxidizing pentanol. Indlela evamile iwukusabela nge-pentanol nge-oxidizing ejenti efana ne-oxygen noma i-hydrogen peroxide, nokusheshisa ukusabela nge-catalyst efana ne-potassium chromate noma i-cerium oxide.

Ulwazi Lokuphepha:

- I-2-pentaone iyavutha futhi kufanele igcinwe kude namalangabi avulekile kanye namazinga okushisa aphezulu.

- Gqoka amagilavu okuzivikela, izingilazi zokuzivikela, nesivikelo sobuso ukuze ugweme ukuthintana namehlo, isikhumba, kanye nomhwamuko.

- Imfucuza kufanele ilahlwe ngokuhambisana nemithetho nemithetho yendawo, futhi akufanele ilahlwe emanzini noma endaweni ezungezile.

- Lapho ugcina futhi usebenzisa, sicela ulandele ngokuqinile izinqubo ezifanele zokusebenza zokuphepha kanye nemihlahlandlela ukuze uqinisekise ukusetshenziswa nokugcinwa kwakho okufanele.

Okwedlule: I-4-Hydroxybenzyl alcohol(CAS#623-05-2)

Olandelayo: I-FEMA 2899(CAS#5452-07-3)
