Folasaga
Dimethyldione o se vailaʻau faʻamaʻi ma le igoa vailaʻau methylbenzophenone. O lo'o ta'ua i lalo se folasaga i meatotino, fa'aoga, metotia o sauniuniga ma fa'amatalaga saogalemu o le dimetethone:
Tulaga lelei:
- Fa'aaliga: E leai se lanu po'o le moli samasama manino vai.
- Solubility: Solu i le vai, ava malosi ma eter solvents.
- Sogisogi: Faatasi ai ma se manogi suamalie faapitoa.
Fa'aaogā:
- Dimethyldiketone o loʻo faʻaaogaina lautele i vailaʻau faʻasolosolo e pei o se solvent, faʻaitiitia le sui ma le faʻamalosi.
- E mafai ona faʻaaogaina e avea o se mea taua tele i le faʻaogaina o meaola ma auai i le tuʻufaʻatasia o le tele o mea faʻapitoa.
Metotia:
- O le auala masani o sauniuniga o le faʻaogaina o le benzoic acid ma le sulfuric acid poʻo le phosphoric acid e maua ai le benzoyl chloride, ona tali atu lea i le methanol ma le sodium carbonate e maua ai le dimethyldione.
- E tele isi auala e saunia ai le dimethyldione, e pei ole chloroformic acid ma le phenylisocyanate reaction, ile chloroazobenzene ma le protonated dimethylamine reaction, ma isi.
Fa'amatalaga Saogalemu:
- O le Dimethyldiketone ose vaila'au fa'alenatura e iai ni o'ona fa'apitoa, ma o le so'ona fa'aalia po'o le manava e ono afaina ai le tino o le tagata.
- Methadiketone e tatau ona teuina i totonu o se atigipusa malulu, mamao ese mai le mumu ma mea faʻamaʻi.
- Fai totigilima puipui ma mata tioata pe a fa'aoga ma aloese mai le pa'i i le pa'u po'o mata.
- E tatau ona mulimulita'i fa'atonuga ma ta'iala mo le saogalemu i totonu o falesu'esu'e po'o fa'agaioiga gaosiga o fale gaosimea.
