Isingeniso
2,5-Difluorobenzaldehyde. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
I-2,5-I-Difluorobenzaldehyde iwuketshezi olungenambala ukuya kokuphuzi olunophawu oluqinile lokusha, iphunga elimnandi endaweni yezinga lokushisa. Ayincibiliki emanzini kodwa ingancibilika kuzincibilikisi zemvelo ezifana ne-ethanol, i-toluene, njll.
Sebenzisa:
I-2,5-Difluorobenzaldehyde inohlu olubanzi lwezinhlelo zokusebenza ku-organic synthesis. Ingasetshenziswa njengesandulela sokuhlanganiswa kwezinhlanganisela ezinuka kamnandi, okuphuma ku-paraphthalenedione, nama-molecule e-bioactive. Ingasetshenziswa futhi ekuhlanganiseni kwezakhiwo ze-organometallic, izigqoko ezisebenza kahle kakhulu namadayi.
Indlela:
I-2,5-difluorobenzaldehyde ingalungiswa ngokusabela kwe-benzaldehyde ne-hydrogen fluoride. Lokhu kusabela kuvame ukwenziwa ngaphansi kwezimo ezine-asidi futhi kungafezwa ngokusebenzisa i-hydrofluoric acid njengomthombo we-hydrogen fluoride.
Ulwazi Lokuphepha:
Izinyathelo zokuqapha ezidingekayo kufanele zithathwe lapho kusingathwa i-2,5-difluorobenzaldehyde. Inezinto ezicasulayo esikhumbeni, emehlweni nasemgudwini wokuphefumula. Izibuko zokuvikela amakhemikhali, amagilavu nezingubo zokuzivikela kufanele zigqokwe futhi ukuxhumana okuqondile kufanele kugwenywe. Uma ingena emehlweni noma esikhunjeni sakho, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha ngokushesha ngangokunokwenzeka. Ngesikhathi sokusebenza, kufanele igcinwe kude nemithombo yomlilo futhi igweme intuthu kanye nentuthu ukugwema umlilo nokuqhuma.
Lesi isingeniso esifushane sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2,5-difluorobenzaldehyde. Uma kudingeka, qiniseka ukuthi uyayiqonda futhi ulandela imithetho nesiqondiso sokuphepha kwaselabhorethri ngaphambi kokuphatha noma ukusetshenziswa.
