Omaka bomkhiqizo

I-2-Bromo-3-pyridine carboxaldehyde iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

Ikhwalithi:
I-2-Bromo-3-pyridine formaldehyde iwuketshezi olungenambala ukuya kokuphuzi okuphaphathekile olunephunga eliyisici le-pyridine ne-aldehyde. Iyancibilika kuzincibilikisi eziningi eziphilayo ezingeni lokushisa lasekamelweni futhi ayincibiliki emanzini. Kuyinhlanganisela ene-reactivity eqinile engabhekana nokusabela okuhlukahlukene kwemvelo ngaphansi kwezimo ezithile.

Sebenzisa:
I-2-Bromo-3-pyridine formaldehyde inohlu olubanzi lwezinhlelo zokusebenza ku-organic synthesis. Ingabamba iqhaza ekuphenduleni okuthile njengokusabela kwe-borate etherification, ukusabela kwe-aldol condensation, njll.

Indlela:
I-2-Bromo-3-pyridine formaldehyde ingalungiswa ngokusabela i-3-pyridine formaldehyde nge-hydrogen bromide. I-Hydrogen bromide iqala idlule ebhodleleni lokugeza igesi ibe yisisombululo se-methanol esingu-3-pyridine formaldehyde, bese ingxube yokusabela iyashisisa. Ngemuva kokuthi ukusabela kuqediwe, umkhiqizo ohlosiwe utholakala ngezindlela ezifana nokucwiliswa kwesitimu noma ukukhipha.

Ulwazi Lokuphepha:
I-2-Bromo-3-pyridine carboxaldehyde iyinhlanganisela yemvelo edinga izinyathelo ezifanele zokuphatha eziphephile lapho isetshenziswa noma iphathwa. Kungacasula futhi kudle isikhumba, amehlo, kanye nomgudu wokuphefumula. Lapho usetshenziswa, qinisekisa ukuthi kungena umoya omuhle futhi ugqoke izinto zokuzivikela ezifana namagilavu ​​okuzivikela, izibuko, namamaski. Gwema ukuhogela, ukukungenisa, noma ukuthintana nesikhumba. Lapho igcinwa, kufanele igcinwe kude nezinto ezivuthayo kanye nama-oxidants futhi igcinwe endaweni epholile, eyomile.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
