Intshayelelo
I-3-hydroxy-2-butanone, eyaziwa ngokuba yi-butyl ketone acetate okanye i-butyl acetate ether, i-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-3-hydroxy-2-butanone:
Umgangatho:
- Imbonakalo: 3-Hydroxy-2-butanone lulwelo olungenambala.
- Ukunyibilika: Inyibilika emanzini nakwizinyibilikisi ezininzi eziphilayo.
Sebenzisa:
- I-Chemical synthesis: I-3-hydroxy-2-butanone ingasetyenziselwa njenge-reagent kwi-organic synthesis kwaye idlala indima yeqela le-ester kwezinye iimpendulo.
Indlela:
- I-3-Hydroxy-2-butanone inokuphendulwa nge-hydrogen peroxide nge-butyl acetate ukufumana i-hydroxyketone ehambelanayo.
Ulwazi ngoKhuseleko:
- I-3-Hydroxy-2-butanone inetyhefu ephantsi phantsi kweemeko eziqhelekileyo zokusetyenziswa, kodwa kufuneka isetyenziswe ngokuqaphela.
- Ukubonakaliswa kwe-3-hydroxy-2-butanone kunokubangela ukucaphuka kwamehlo kunye nolusu, kwaye ukudibanisa ngokuthe ngqo kufuneka kugwenywe.
- Xa usebenzisa i-3-hydroxy-2-butanone, kufuneka kuthathwe unonophelo ukuze kuqinisekiswe ukusebenza okukhuselekileyo kunye nomoya ofanelekileyo kunye nokusetyenziswa kwezixhobo zokukhusela zomntu.
