Folasaga
1,3-Difluorobenzene o se faʻalapotopotoga faʻapitoa. O loʻo taua i lalo se faʻamatalaga auiliili i meatotino, faʻaoga, metotia sauniuni ma faʻamatalaga saogalemu o le 1,3-difluorobenzene:
Tulaga lelei:
1,3-Difluorobenzene o se faʻapipiʻi organofluorine ma maualuga faʻamaʻi. E le mafai ona mu ae e tali atu i ni mea fa'ama'i malosi. 1,3-Difluorobenzene e soluble i solu masani masani e pei ole ethanol, eter ma chloroform, ma le mafai ona solu i le vai.
Fa'aaogā:
1,3-difluorobenzene o loʻo i ai se aoga faʻapitoa i le faʻaogaina o meaola. E mafai ona fa'aaogaina e fai ma mea fa'afofoga fa'afofoga i le fa'aogaina o meaola, mo se fa'ata'ita'iga e fai ma fa'amumū fa'atosina mo mea manogi. 1,3-difluorobenzene e mafai foi ona faʻaaogaina i le tuʻufaʻatasia o mea faʻapipiʻi, le sauniuniga o masini optoelectronic organic ma isi fanua.
Metotia:
1,3-Difluorobenzene e mafai ona saunia e le fluorination o benzene. O auala masani e fa'aogaina ai le fa'aogaina o le hydrogen fluoride e fai ma sui o le fluorinating po'o le fa'aogaina o mea fa'apipi'i ferrous fluoride mo tali fa'afefe.
Fa'amatalaga Saogalemu:
Ole puipuiga ole saogalemu e tatau ona faia pe a faʻaaogaina le 1,3-difluorobenzene:
1.1,3-Difluorobenzene ei ai ni o'ona fa'apitoa, lea e ono afaina ai le pa'u, fa'afefe o le kesi po'o le fa'alavelave fa'afuase'i. O mea faigaluega puipuia e pei o totigilima, mata puipui, ma matapulepule e tatau ona ofuina a'o fa'aoga.
2. Aloese mai le fa'afeso'ota'i ma vaila'au fa'ama'i malosi e 'alofia ai le mu po'o le pa.
3. E tatau ona teuina i totonu o se nofoaga mago, malulu ma lelei le savili, mamao mai le afi ma mea e mu.
5. Aloese mai le fa'afefiloi ma isi vaila'au ma 'alo'ese mai tamaiti ma tagata e le iloa fa'agaioiga.
