Hoʻolauna

ʻO 3-Methyl-pyridine-4-carboxaldehyde kahi mea hoʻohuihui. He wai waihoʻoluʻu a melemele paha me kahi ʻala ʻala.

 

Hoʻohana pinepine ʻia ʻo 3-Methyl-pyridin-4-carboxaldehyde ma ke ʻano he waena i ka synthesis organik.

 

ʻO kahi ala maʻamau e hoʻomākaukau ai i ka 3-methyl-pyridine-4-carboxaldehyde ma o ka oxidizing methylpyridine, hiki ke hana ʻia me ka hoʻohana ʻana i nā mea hoʻoheheʻe e like me ka oxygen, hydrogen peroxide, a i ʻole benzoyl peroxide.

 

ʻIke palekana: ʻO ka 3-methyl-pyridin-4-carboxaldehyde he mea hoʻohuihui kino i loaʻa i ka huhū a me ka ʻona. Pono e mālama ʻia e pale aku i ka pili ʻana me ka ʻili a me nā maka, a e mālama pono i ka ea. I ka lawelawe ʻana a mālama ʻana, pono e hahai ʻia nā kaʻina hana palekana kūpono a pono e hāʻawi ʻia nā lako pale pilikino kūpono e like me nā mīkina lima laboratory a me nā aniani palekana. Inā loaʻa ka ʻai ʻana, a i ʻole ka pili ʻana, e ʻimi koke i ka lāʻau lapaʻau.
