Umgangatho:
- Imbonakalo: Ulwelo olungenambala okanye olutyheli.
- Ukunyibilika: ukunyibilika kwizinyibilikisi eziphilayo ezifana neealkoholi, iietha kunye neehydrocarbon ezikloriniweyo.
Sebenzisa:
- 2,4-Difluorobenzaldehyde isoloko isetyenziswa njengendawo ephakathi kwi-synthesis yezinye izinto eziphilayo.
-Izicelo ezibalulekileyo ekudibaneni kweefotosensitizers ezithile.
Indlela:
I-2,4-difluorobenzaldehyde ilungiswa ngokubanzi ngezi ndlela zilandelayo:
- Inokufumaneka ngokuphendula i-benzaldehyde kunye ne-hydrogen fluoride, ngokuqhelekileyo kwi-40-50 ° C.
- Isenokulungiswa ngokusabela nge-chlorobenzaldehyde kunye ne-hydrogen fluoride okanye i-fluorosilanes.
Ulwazi ngoKhuseleko:
- 2,4-Difluorobenzaldehyde inokucaphukisa ulusu, amehlo, kunye nenkqubo yokuphefumula. Izixhobo ezifanelekileyo zokukhusela ezinjengeeglavu, izibuko, kunye nokhuseleko lokuphefumla kufuneka zinxitywe xa usebenzisa okanye uphethe.
- Kufuneka igcinwe kude nomlilo kunye namaqondo obushushu aphezulu, kwindawo epholileyo, eyomileyo, nengena umoya, kwaye ngokwahlukileyo kwi-oxidants kunye nezinto ezinamandla ze-alkaline.
- Jonga kwaye ulandele iinkqubo ezifanelekileyo zokusebenza zokhuseleko ngokweenkcukacha phambi kokusetyenziswa.
