Intshayelelo
I-2,4-difluorobenzylbromide yi-organic compound kunye ne-chemical formula C7H5BrF2. Lulwelo olungenambala nevumba elinamandla. Oku kulandelayo yinkcazo yezinye iipropati, ukusetyenziswa, iindlela kunye nolwazi lokhuseleko lwe-2,4-difluorobenzylbromide:
Indalo:
-Inkangeleko: 2,4-difluorobenzylbromide ngulwelo olungenambala.
-I-Solubility: Iyakwazi ukunyibilika kunye ne-solvents yezinto eziphilayo, ezifana ne-ethanol, i-chloroform kunye ne-dimethylformamide.
Sebenzisa:
-2,4-difluorobenzylbromide ingasetyenziswa njengendawo ephakathi kwi-organic synthesis kwaye isetyenziswe kwi-synthesis yezinye iikhompawundi.
-Inokusetyenziswa kwakhona njengento ekrwada kwintsimi ye-pesticides kunye namayeza.
Indlela:
-2,4-difluorobenzylbromide idla ngokulungiswa ngokuphendula i-2,4-difluorobenzoic acid kunye ne-bromine.
-Indlela ethile yokulungiselela inokulungelelanisa iimeko zokusabela kunye nee-reagents ezisetyenziswayo njengoko zifunekayo.
Ulwazi ngoKhuseleko:
- I-2,4-difluorobenzylbromide iyacaphukisa kwaye ifuna ingqalelo kumanyathelo okukhusela afana nokugqoka iiglavu kunye nempahla yokukhusela.
-Kuphephe ukuphefumla, ukudibana nesikhumba kunye namehlo ngexesha lokusetyenziswa.
-Kwimeko yokuphefumla ngengozi okanye ukudibana ngengozi, umntu ochaphazelekayo kufuneka ahanjiswe ngokukhawuleza emoyeni omtsha kwaye aphathwe ngonyango.
-Xa ugcina, gcina i-2,4-difluorobenzylbromide kude nomlilo kunye ne-oxidant ukuphepha umngcipheko womlilo kunye nokudubula.
