Isingeniso
I-2,4-Difluorobenzaldehyde iyinhlanganisela yemvelo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: Uketshezi olungenambala noma oluphuzi.
- Ukunyibilika: kuncibilika kuzincibilikisi zemvelo ezifana notshwala, ama-ether nama-hydrocarbon ane-chlorine.
Sebenzisa:
- 2,4-I-Difluorobenzaldehyde ivame ukusetshenziswa njengendawo ephakathi ekuhlanganiseni ezinye izinhlanganisela eziphilayo.
- Izinhlelo zokusebenza ezibalulekile ekuhlanganisweni kwama-photosensitizers athile.
Indlela:
I-2,4-difluorobenzaldehyde ngokuvamile ilungiswa ngalezi zindlela ezilandelayo:
- Ingatholakala ngokuphendula i-benzaldehyde nge-hydrogen fluoride, ngokuvamile ku-40-50°C.
- Ingalungiswa futhi ngokusabela nge-chlorobenzaldehyde ne-hydrogen fluoride noma i-fluorosilanes.
Ulwazi Lokuphepha:
- 2,4-Difluorobenzaldehyde ingase icasule isikhumba, amehlo, kanye nesistimu yokuphefumula. Izinto zokuvikela ezifanele ezifana namagilavu, izibuko, nokuvikela ukuphefumula kufanele kugqokwe lapho usebenzisa noma uphatha.
- Kufanele igcinwe kude nomlilo namazinga okushisa aphezulu, endaweni epholile, eyomile, enomoya omuhle, futhi ngokuhlukana nama-oxidants kanye nezinto ezinamandla ze-alkaline.
- Qaphela futhi ulandele izinqubo ezifanele zokusebenza zokuphepha ngokuningiliziwe ngaphambi kokusetshenziswa.
