- Sehlopha sa Ketone:E fana ka libaka tsa marang-rang bakeng sa ho hokahanya le metsoako e kang hydrazines.
Setšoantšo sa DAAM
DAAM e entsoe ka karabelo ea joala ea diacetone ka acrylonitrile, e lateloa ke mohato oa catalytic hydrogenation kapa hydrolysis ho hlahisa sehlopha sa amide. Ts'ebetso ea tlhahiso e netefatsa sehlahisoa se phahameng se hloekileng se loketseng likopo tsa indasteri.
Mehato ea Bohlokoa ea Maikutlo:
- Diacetone Alcohol + Acrylonitrile → Motsoako oa Bohareng
- Hydrogenation kapa Hydrolysis → Diacetone Acrylamide
