Hoʻolauna

ʻO ka 2-bromo-3-methoxypyridine he mea hoʻohuihui olaola me ke ʻano kemika C6H6BrNO. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.

 

ʻAno:

-Nani: wai kala ʻole

-Solubility: Hiki ke hoʻoheheʻe ʻia i ka ethanol anhydrous a me nā mea hoʻoheheʻe Etera

-Pila paila: 167-169 ° C

-Ke kiʻekiʻe: 1.568 g/mL

 

E hoʻohana:

Loaʻa i ka 2-bromo-3-methoxypyridine kekahi mau noi ma ke kahua o ke kemika:

-Ma ke ʻano waena: hiki ke hoʻohana ʻia e synthesize i nā mea hoʻohui organik ʻē aʻe, e like me nā lāʻau lapaʻau, pesticides a me nā mea hoʻonaninani.

-Organic synthesis: Hiki iā ia ke komo i nā ʻano hopena like ʻole, e like me ka electrophilic substitution reactions, condensation reactions, etc.

 

Hanana:

ʻO nā ʻano hana synthesis 2-bromo-3-methoxypyridine ka mea nui:

1. Ma ka hopena o ka 3-methoxypyridine a me ka bromine: 3-methoxypyridine i hoʻopili ʻia me ka bromine a hoʻomehana ʻia ma lalo o nā kūlana alkaline e loaʻa ai ka huahana 2-bromo-3-methoxypyridine.

2. Ma ka hopena o ka pyridine a me ka 2-Bromo methyl ether: pyridine a me 2-Bromo methyl ether reaction, ma lalo o nā kūlana kūpono no ka hoʻomehana ʻana a i ʻole ka hoʻohana ʻana i ka catalyst e hana i ka huahana i makemake ʻia.

 

ʻIke palekana:

Pono ka mālama ʻana i ka palekana o 2-bromo-3-methoxypyridine. Eia kekahi mau ʻōlelo aʻoaʻo palekana:

-E pale i ka inhalation, pili me ka ʻili, a i ʻole ke komo ʻana i nā maka. E hoʻohana i nā mea pale kūpono e like me nā mīkina lima, nā maka aniani a me nā pale alo i ka wā e hoʻohana ai.

-I ka mālama ʻana, pono e waiho ʻia ma kahi wahi e hoʻoheheʻe maikaʻi ʻia, ma kahi mamao o ke ahi a me nā mea oxidizing.

-E heluhelu pono i ka pepa ʻikepili palekana kūpono ma mua o ka hoʻohana ʻana a hoʻohana e like me nā kaʻina hana kūpono.
