Taw qhia

6-CHLORO-4-METHYLPYRIDIN-3-CARBOXALDEHYDE (2-CHLORO-5-FORMYL-4-PICOLINE) yog ORGANIC COMPOUND. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:

Zoo:

- Cov tsos mob: 6-Chloro-4-methylpyridine-3-carboxaldehyde yog xim tsis muaj xim rau cov kua daj daj.

- Solubility: Nws tuaj yeem yaj hauv ntau cov kuab tshuaj organic, xws li ethanol, ether, thiab chloroform.

- Stability: Cov tshuaj no ruaj khov ntawm chav tsev kub, tab sis tuaj yeem decompose nyob rau hauv tshav kub, nplaim taws, los yog acidic heev.

Siv:

- 6-chloro-4-methylpyridine-3-carboxaldehyde yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis thiab feem ntau siv rau hauv kev npaj ntawm lwm cov organic tebchaw.

Txoj kev:

- 6-Chloro-4-methylpyridine-3-carboxaldehyde feem ntau yog npaj los ntawm cov tshuaj tiv thaiv synthesis zoo ib yam li cov kauj ruam hauv qab no:

1. 4-methylpyridine raug kho nrog alkali kom tau txais cov ions tsis zoo sib xws.

2. Cov ions tsis zoo yog reacted nrog cuprous chloride los ua alkyl tooj liab intermediates.

3. Alkyl tooj liab intermediates yog reacted nrog formaldehyde los ua 6-chloro-4-methylpyridine-3-carboxaldehyde.

Cov ntaub ntawv kev nyab xeeb:

- 6-Chloro-4-methylpyridine-3-carboxaldehyde tej zaum yuav muaj kev phom sij rau tib neeg lub cev, thiab yuav tsum muaj kev tiv thaiv kev nyab xeeb thaum siv, xws li hnav cov khoom tiv thaiv tsim nyog (xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv).

- Nws yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav thiab zoo-ventilated, deb ntawm hluav taws thiab oxidants.

- Tsis txhob nqus pa, tiv thaiv daim tawv nqaij thiab noj thaum tuav thiab siv.

- Tam sim ntawd tom qab sib cuag, yaug qhov chaw ntawm daim tawv nqaij nrog dej kom txaus thiab nrhiav kev kho mob.
