Isingeniso
I-2-Fluoro-4-bromobenzaldehyde iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwale nhlanganisela:
Ikhwalithi:
- Ukubukeka: I-2-Fluoro-4-bromobenzaldehyde iqinile engenambala ukuya kokuphuzi.
- I-Solubility: Incibilika kwezinye izincibilikisi ze-polar njenge-ethanol ne-methylene chloride.
- Ukuzinza: I-2-Fluoro-4-bromobenzaldehyde iyinhlanganisela engazinzile ethinteka kalula ukukhanya nokushisa futhi ingabola kalula ngokushisisa.
Sebenzisa:
- Ingasetshenziswa nasezindaweni ezifana ne-dayi synthesis, ama-catalysts, nezinto ezibonakalayo.
Indlela:
I-2-Fluoro-4-bromobenzaldehyde ingahlanganiswa ngezindlela ezihlukahlukene, njenge:
I-2-bromo-4-fluorobenzyl alcohol ingasabela ngesixazululo esine-acidic, isisombululo sokusabela singasuswa futhi sigaywe ukuze kutholwe umkhiqizo ohlanziwe.
Ingabuye itholakale ngokufaka i-oxidizing 4-fluorostyrene phambi kwe-ethyl bromide.
Ulwazi Lokuphepha:
I-2-Fluoro-4-bromobenzaldehyde iyinhlanganisela yemvelo edinga izinqubo zokuphepha ezifanele kanye nezinyathelo okufanele zilandelwe:
- I-2-Fluoro-4-bromobenzaldehyde iyacasula futhi ingase ibangele ukulimala kwamehlo, isikhumba, kanye nendlela yokuphefumula. Lapho usebenza, kuyadingeka ukuthi ugqoke izinto zokuzivikela ezifanele njengezibuko, amagilavu namamaski.
- Gwema ukuhogela umhwamuko ophuma emagesini noma ezixazululweni zawo. Onogada kufanele basetshenziswe noma basetshenziswe endaweni engenawo umoya.
- Gwema ukuchayeka elangeni noma ukushisa. Kufanele igcinwe endaweni epholile, eyomile ukuze igweme ukuthintana nama-oxidants.
- Ungaxubani i-2-fluoro-4-bromobenzaldehyde nama-oxidizing agent futhi ungachithi emanzini noma kwezinye izindawo.
Ngaphambi kokusebenzisa i-2-fluoro-4-bromobenzaldehyde, qiniseka ukuthi ufunda futhi uyawaqonda amaphepha edatha okuphepha afanelekile namamanuwali okusebenza, futhi ulandele ukuphatha nokulahla izinqubo ezifanele.
