Intshayelelo
I-β-butanone, ekwaziwa ngokuba yi-β-Turkone, yikhompawundi ephilayo. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-β-butanone:
Umgangatho:
- β-MEK lulwelo olungenambala kunye nencasa ekhethekileyo enevumba elimnandi.
- I-beta-butanone eqhelekileyo kukubunjwa kwee-dimers kunye neepolymers ngamabhondi e-hydrogen ngaphakathi kwe-molecule, engakhokelela ekutshintsheni kwiimpawu zayo.
Sebenzisa:
- I-β-MEKT isetyenziswa ngokubanzi kwishishini lemichiza njenge-solvent, i-reactant kunye nephakathi.
- Ikwasetyenziswa njengesinyibilikisi kwiipeyinti kunye neglu kunye nakwimizi-mveliso yoshicilelo nedayi.
Indlela:
- I-β-MEKONE inokwenziwa yi-ketone deterioration reaction. Le mpendulo kukusabela ibutanol nge-ammonium chloride kunye ne-penta [2,2,2] oxide ukuvelisa i-β-butanone kwiqondo lokushisa elifanelekileyo.
Ulwazi ngoKhuseleko:
- I-β-MEKT inetyhefu ephantsi kodwa isafuna ukuphathwa ngononophelo.
- Lulwelo olunokutsha kwaye kufuneka lugcinwe kude namadangatye avulekileyo kunye nemithombo yobushushu obuphezulu.
- Ukungena komoya okulungileyo kufuneka kugcinwe xa uphathwa okanye ugcina i-β-butanone.
- Ukunyamekela kufuneka kuthathwe ukuphepha ukudibanisa ngokuthe ngqo kwesikhumba kunye namehlo xa usebenzisa.
