Folasaga
2,4′-Dichlorobenzophenone (lea e taʻua o Dichlorodiphenylketone) o se faʻalapotopotoga faʻapitoa. O nisi nei o meatotino, fa'aoga, metotia o sauniuniga, ma fa'amatalaga saogalemu:
Tulaga lelei:
- Faʻaaliga: 2,4′-Dichlorobenzophenone o se tioata e leai ni lanu poʻo se paʻepaʻe tioata paʻepaʻe.
- Solubility: 2,4′-dichlorobenzophenone e soluble i solvents organic pei ole ethanol ma le dimethylformamide.
Fa'aaogā:
2,4′-Dichlorobenzophenone o loʻo i ai faʻaoga taua i le faʻaogaina o meaola:
- I le avea ai o se faʻamalosi: e mafai ona faʻaaogaina mo le tele o gaioiga faʻale-aganuʻu, e pei o le faʻaitiitia, faʻamaʻi, amide ma faʻamaʻi.
- I le avea ai o se vaeluagalemu: E mafai ona faʻaaogaina e avea o se mea taua tele i le tuʻufaʻatasia o isi mea faʻapipiʻi.
- I le avea ai o se mea faʻaola: e mafai ona faʻaaogaina e saunia ai mea faʻapipiʻi ata, lanu felanulanuaʻi ma polymers.
Metotia:
2,4'-Dichlorobenzophenone e masani ona saunia e ala i le tali atu o le dichlorobenzophenone ma le chloroacetic acid. E i ai ituaiga eseese o metotia sauniuni faapitoa, e aofia ai le auala e tali atu ai le solvent, auala faʻapipiʻi vaega malosi ma le faʻaogaina o le kasa.
Fa'amatalaga Saogalemu:
2,4'-Dichlorobenzophenone e itiiti le oona ae e tatau lava ona faʻalatalata ma le faʻaeteete:
- I le avea ai o se vailaʻau, e tatau ona aloese mai le faʻafesoʻotaʻi saʻo ma le paʻu, mata, ma le manava o lona pefu.
- E tatau ona faia faiga lelei ea i le taimi o le taotoga e puipuia ai le manavaina o ausa ma pefu.
- Pe a fa'afuase'i ona 'ai po'o le manava, fa'afeso'ota'i se foma'i ma fa'afeso'ota'i se tagata tomai faapitoa.
