Hoʻolauna

ʻO 2-ETHOXY-5-NITROPYRIDINE he mea hoʻohuihui mea ola me ke ʻano kemika C8H8N2O3.

 

ʻAno:

ʻO 2-ETHOXY-5-NITROPYRIDINE he paʻa kalamele melemele me kahi ʻala ʻokoʻa. He helu hehee ia ma kahi o 56-58 degere Celsius a me ka lae paila ma kahi o 297-298 degere Celsius. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai i ka mahana maʻamau, akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka waiʻona, ether, a me nā mea ʻē aʻe.

 

E hoʻohana:

Hiki ke hoʻohana ʻia ka 2-ETHOXY-5-NITROPYRIDINE ma ke ʻano he koʻikoʻi koʻikoʻi i ka synthesis organik, hoʻohana nui ʻia i ka synthesis kemika, lāʻau lapaʻau, dyes a me nā māla ʻē aʻe. Ma ke ʻano he pūhui multifunctional, hiki ke hoʻohana ʻia e synthesize i nā mea hoʻohui ʻē aʻe, e like me nā lāʻau lapaʻau, nā pesticides a me nā dyes.

 

Hanana:

2-ETHOXY-5-NITROPYRIDINE he nui nā ʻano hana hoʻomākaukau, hoʻohana ʻia kekahi o ia e ka hopena o 5-chloropyridine a me ka ethyl alcohol ma lalo o nā kūlana alkaline. Pono nā ʻanuʻu synthesis kikoʻī i ka hana hoʻokolohua kikoʻī a me ka ʻike kemika, e ʻoluʻolu e hoʻokō i ka hopena synthesis i loko o kahi kaiapuni.

 

ʻIke palekana:

Hiki i ka 2-ETHOXY-5-NITROPYRIDINE ke hoʻonāukiuki i ka wā e hoʻopili ai me ka ʻili a me nā maka, no laila pono e hoʻokomo i nā lako pale pilikino kūpono i ka wā o ka hana a me ka lawelawe ʻana. I ka manawa like, he paʻa paʻa ke ahi a pono e mālama ʻia mai ke ahi a me ka wela kiʻekiʻe e pale aku i nā kinoea a me nā mahu. I ka wā o ka mālama ʻana a me ka mālama ʻana, e nānā i nā kaʻina hana palekana kūpono a mālama iā lākou i loko o nā pahu i hoʻopaʻa ʻia. Inā loaʻa kahi pōʻino, e ʻoluʻolu e hana koke i nā hana pilikia kūpono a e ʻimi i ke kōkua olakino.
