Hoʻolauna

6-CHLORO-4-METHYLPYRIDIN-3-CARBOXALDEHYDE (2-CHLORO-5-FORMYL-4-PICOLINE) HE COMPOUND ORGANIC. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:

 

ʻAno maikaʻi:

- Ke ʻano: 6-Chloro-4-methylpyridine-3-carboxaldehyde he wai waihoʻoluʻu ʻole a ʻeleʻele melemele.

- Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe, e like me ka ethanol, ether, a me ka chloroform.

- Paʻa: Paʻa kēia pūhui i ka mahana wela, akā hiki ke hoʻoheheʻe ʻia ma lalo o ka wela, ka lapalapa, a i ʻole nā ​​kūlana acidic ikaika.

 

E hoʻohana:

- ʻO 6-chloro-4-methylpyridine-3-carboxaldehyde kahi mea koʻikoʻi i waena o ka synthesis organik a hoʻohana pinepine ʻia i ka hoʻomākaukau ʻana i nā mea hoʻohui ʻē aʻe.

 

Hanana:

- 6-Chloro-4-methylpyridine-3-carboxaldehyde ka mea maʻamau i hoʻomākaukau ʻia e ka hopena synthesis e like me nā pae aʻe:

1. Hoʻohana ʻia ka 4-methylpyridine me ka alkali no ka loaʻa ʻana o nā iona ʻino e pili ana.

2. Hoʻopili ʻia nā iona ʻino me ka cuprous chloride e hana i nā mea waena keleawe alkyl.

3. Hoʻopili ʻia nā mea waena keleawe alkyl me formaldehyde e hana i 6-chloro-4-methylpyridine-3-carboxaldehyde.

 

ʻIke palekana:

- Hiki i ka 6-Chloro-4-methylpyridine-3-carboxaldehyde ke hoʻopōʻino i ke kino o ke kanaka, a pono e mālama ʻia nā hana palekana i ka wā e hoʻohana ai, e like me ke komo ʻana i nā mea pale kūpono (e like me nā mīkina lima, nā maka aniani, a me nā lole pale).

- Pono e mālama ʻia ma kahi ʻoluʻolu, maloʻo a me ka makani maikaʻi, ma kahi mamao o ke ahi a me nā mea ʻona.

- Hōʻalo i ka inhalation, pili i ka ʻili a me ka ʻai ʻana i ka wā e lawelawe ai a hoʻohana.

- Ma hope koke o ka hoʻopili ʻana, holoi i ka ʻili i haumia me ka wai nui a ʻimi i ka lāʻau lapaʻau.
