Isingeniso
I-3-bromo-4-methoxypyridine iyinhlanganisela ye-organic enefomula yamakhemikhali ye-C6H6BrNO kanye nesisindo samangqamuzana angu-188.03. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
1. Ukubukeka: I-3-bromo-4-methoxypyridine iqinile ngokuphuzi kuya kokuphuzi.
2. ukunyibilika: kuncibilika kuzincibilikisi zemvelo njenge-ether nama-hydrocarbon ane-chlorine, okungancibiliki emanzini.
3. indawo encibilikayo: cishe 50-53 ℃.
4. ukuminyana: cishe ngu-1.54 g/cm.
Sebenzisa:
I-3-bromo-4-methoxypyridine iyinhlanganisela ebalulekile ye-organic synthesis, evame ukusetshenziswa ekuhlanganiseni kwezibulala-zinambuzane, imithi kanye nezinye izinhlanganisela eziphilayo. Inezinhlobonhlobo zezicelo emkhakheni wocwaningo lwamakhemikhali nemithi.
Indlela Yokulungiselela:
I-3-bromo-4-methoxypyridine ngokuvamile ihlanganiswa ngezinyathelo ezilandelayo:
1. I-2-bromo-5-nitropyridine isabela nge-methanol ukuze ithole i-2-methoxy-5-nitropyridine.
2. I-2-methoxy-5-nitropyridine isabela nge-cuprous bromide elungiselelwe nge-sulfuric acid ukuthola i-3-bromo-4-methoxypyridine.
Ulwazi Lokuphepha:
1. I-3-bromo-4-methoxypyridine iyacasula futhi kufanele igweme ukuthintana nesikhumba, amehlo kanye nomgudu wokuphefumula.
2. ekuphatheni nasekusetshenzisweni, kufanele agqoke izinto zokuzivikela ezifanele, njengamagilavu nezingilazi zokuzivikela.
3. Ukugcina kufanele kuvimbele ukuthintana nama-oxidants nama-asidi aqinile, futhi kugcine isitsha sivaliwe.
4. Ngaphansi kwezimo ezifanele zokusetshenziswa nokugcinwa, i-3-bromo-4-methoxypyridine iyikhemikhali ephephile uma kuqhathaniswa, kodwa kusadingeka ukuthi isetshenziswe ngokuqapha.
