| Tulaga lamatia | 36/37/38 – Fa'aitaita'i i mata, faiga manava ma le pa'u. |
| Fa'amatalaga Saogalemu | 24/25 – Aloese mai le fa'afeso'ota'i ma le pa'u ma mata. |
Folasaga
3,4-Dimethylbenzophenone, e lauiloa foi o le ketocarbonate poʻo Benzoin. O lo'o taua i lalo se fa'amatalaga o lona natura, fa'aoga, sauniuniga ma fa'amatalaga saogalemu:
natura:
- Faʻaaliga: 3,4-Dimethylbenzophenone o se tioata paʻepaʻe paʻepaʻe.
-Solubility: E toetoe lava a le mafai ona solu i totonu o le vai, ma e maualuga lona solubility i solvents organic pei ole ethanol ma le dimethylformamide.
-Melting point: O le faʻafefeteina o le 3,4-dimethylbenzophenone e tusa ma le 132-134 tikeri Celsius.
-O mea tau kemisi: O se eletise eletise e mafai ona auai i gaioiga eseese e pei o le faʻapipiʻiina o le hydrogen, faʻamaʻi faʻamaʻi-faʻaitiitia i le va o le ketone carbon ma le methyl.
Fa'aaogā:
- 3,4-Dimethyl benzophenone e masani ona faʻaaogaina e avea o se reagent mo faʻasologa o meaola faʻasolosolo.
-E mafai ona faʻaaogaina e avea o se reagent electrophilic e auai i tali faʻaopoopo electrophilic, faʻavae ketone carbonate ma isi gaioiga.
-E mafai foi ona faʻaaogaina e avea o se photosensitizer mo lithography, faʻamaʻi mama ma isi fanua.
Sauniuniga auala:
O le tasi metotia mo le saunia o le -3,4-dimethyl benzophenone o le faʻaogaina o le barone. O laasaga o le tali e faʻapea: Muamua, o le styrene e tali atu i le bromine sili atu i lalo o le malamalama poʻo le ultraviolet moli e fausia ai le β-bromostyrene. O le β-bromostyrene e faʻafeiloaʻi ma se hydroxide (eg, NaOH) e fausia ai le 3,4-dimethylbenzophenone.
-O le isi auala sauniuni o le tali atu lea i le acetophenone ma le sodium bromide i lalo o tulaga alkaline e gaosia ai le 3,4-dimethyl benzophenone.
Fa'amatalaga Saogalemu:
- 3,4-Dimethylbenzophenone e itiiti le oona.
- Aloese mai le pa'u o le pa'u ma le manava pe a fa'aaoga.
-Ruyi faʻafesoʻotaʻi fafo i le paʻu, e tatau ona vave fufulu i le tele o vai.
-Afai e manavaina, ia vave alu i se nofoaga e lelei le savili.
-E fautuaina e fai totigilima puipui talafeagai ma mea manava ile taimi ole taotoga.
-Pe a faʻaaoga ma teuina, faʻamolemole mulimuli i faiga saogalemu ma tuʻu ese mai le mafai e tamaiti.
