Isingeniso
I-3,4-Difluorobsyl bromide iyinhlanganisela yemvelo enefomula yamakhemikhali ethi C7H5BrF2. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
- 3,4-Difluorobenzyl bromide uketshezi olungenambala.
-Inokuminyana okungu-1.78g/cm³ kanye nephuzu lokubila elingu-216-218 degrees Celsius.
-Emazingeni okushisa asekamelweni, ingancibilika kuma-solvents ephilayo njenge-ether ne-chloroform.
Sebenzisa:
- I-3,4-Difluorobenzyl bromide ivame ukusetshenziswa njenge-reagent ku-organic synthesis. Ingasetshenziselwa ukuhlanganisa izinhlanganisela eziphilayo nezakhiwo ezithile kanye nezakhiwo.
-Ingasetshenziswa futhi njengendawo ephakathi kwemithi nezibulala-zinambuzane.
Indlela Yokulungiselela:
Ukulungiswa kwe--3,4-Difluorobenzyl bromide kungatholakala ngokuphendula i-3,4-difluorobenzaldehyde nge-sodium bromide ngaphansi kwezimo zokusabela ezifanele.
Ulwazi Lokuphepha:
- I-3,4-Difluorobenzyl bromide idinga ukunakwa kwezinyathelo zokuphepha ngesikhathi sokugcina nokuphatha.
-Kufanele igcinwe esitsheni esivaliwe, gwema ukuthintana nomoya kanye nomswakama.
-Gqoka amagilavu okuzivikela afanelekile kanye nezibuko lapho usebenzisa.
-Gwema ukuhogela, ukuhlafuna noma ukuthinta isikhumba ngesikhathi sokuhlinzwa.
-Lapho kulahlwa imfucuza, kufanele iphathwe futhi ilahlwe ngokuhambisana nemithetho kazwelonke neyesifunda efanele.
Sicela uqinisekise ukuthi izinqubo zokuphepha ezifanele zilandelwa ngokuqinile uma usebenzisa lesi sithako, futhi izinyathelo ezifanele zokuvikela zithathwa ngokuya ngesimo esithile. Uma uneminye imibuzo mayelana nokusebenza, sicela uthintane nochwepheshe noma isiqondiso esifanele selabhorethri ye-organic chemistry.
