4 4′-Dimethoxybenzophenone（CAS# 90-96-0)

Folasaga

4,4'-Dimethoxybenzophenone, e taʻua foi o le DMPK poʻo le Benzilideneacetone dimethyl acetal, o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i meatotino, fa'aoga, metotia sauniuni ma fa'amatalaga saogalemu o lenei fa'apotopotoga:

Tulaga lelei:

4,4'-Dimethoxybenzophenone o se vai e leai se lanu e lanu samasama ma le manogi o le benzene. E mu, e maualuga lona mamafa, ma fa'amavae i so'o fa'aola masani e pei ole ethanol, ethers, ma ketones. E le mautu i le ea ma le malamalama ma e mafai ona oʻo i faʻamaʻi faʻamaʻi.

Fa'aaogā:

4,4′-dimethoxybenzophenone e masani ona faʻaaogaina e avea o se faʻamalosi poʻo se faʻalavelave i le faʻaogaina o meaola ma e maualuga lona gaioiga. I le faʻaogaina o meaola, e mafai ona faʻaaogaina i le sauniuniga o aldehydes, ketones, ma isi.

Metotia:

O le auala sauniuni o le 4,4′-dimethoxybenzophenone e mafai ona ausia e ala i le condensation reaction o dimethoxybenzosilane ma benzophenone. O le Dimethoxybenzosilane e tali atu i le sodium borohydride e maua ai le boranol, ona faʻafefeteina lea i le benzophenone e maua ai le 4,4′-dimethoxybenzophenone.

Fa'amatalaga Saogalemu:

4,4'-Dimethoxybenzophenone e faʻafefe i le paʻu ma e ono mafua ai le faʻafefe o mata ma le manava. O faiga puipuia talafeagai e pei o totigilima, mata tioata, ma manava e tatau ona ofuina i le taimi o le tagofiaina ma le faʻaaogaina. I le taimi o le teuina, e tatau ona teuina i se nofoaga malulu, matutu, mamao ese mai le mumu ma oxidants. Fa'amolemole mulimuli i faiga fa'agaioiga saogalemu ma mulimulita'i tulafono ma mana'oga talafeagai uma. I tulaga o fa'alavelave fa'afuase'i, e tatau ona vave faia ni fa'alavelave talafeagai.
