2-Fluoropyridine-5-carboxaldehyde（CAS# 677728-92-6)

Hoʻolauna

He mea hoʻohuihui ia me ka molecular formula C6H4FN, i hoʻololi ʻia e ka hui 5-formaldehyde ma ke apo 2-fluoropyridine. Eia ka wehewehe kikoʻī o nā waiwai, hoʻohana, hoʻomākaukau a me ka ʻike palekana o ka pūhui:

ʻAno:

-Nani: ʻAʻole kala a i ʻole ka wai melemele māmā.

-Solubility: Hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe organik, e like me ka ethanol, acetone, etc.

-Ka helu heheʻe: ma kahi o -5°C.

-Pila paila: ma kahi o 135 ℃.

-Kakaumaha kikoʻī: ma kahi o 1.214g/cm³.

-Maʻiʻo: ʻoi aku ka maʻemaʻe ma mua o 95%.

E hoʻohana:

-he mea pono ma ke ʻano he mea hoʻomaka a i ʻole waena i ka synthesis organik.

-Hoʻohana maʻamau ia i ka lāʻau lapaʻau e hoʻomākaukau i nā lāʻau lapaʻau, e like me nā antipsychotics a me nā lāʻau antineoplastic.

- Hiki ke hoʻohana ʻia ka hui e hoʻomākaukau i nā pesticides, sensitizers, dyes, etc.

Kaʻina hoʻomākaukau:

ʻElua mau ʻano hoʻomākaukau nui:

1. pyridine a me cyanide iodine pane, a laila ka fluorination pane, a hope hoʻohui formaldehyde huahana.

2. Hoʻopili ka pyridine me ka methane a me ka boron trifluoride i 2-methylpyridine, a laila hoʻokō ʻia ka hopena fluorination, a hoʻohui ʻia ka formaldehyde e loaʻa ai ka pyridine.

ʻIke palekana:

-ʻO kahi kūlana o ka huhū a me ka corrosiveness, pono e pale i ka pilina me kaʻili, nā maka a me ka'ōpū hanu.

-E hahai i nā kaʻina hana palekana i ka wā e hoʻohana ai a mālama.

-E hoʻohana i kahi wahi e hoʻoheheʻe maikaʻi ʻia a hoʻohana i nā mea pale kūpono, e like me nā mīkina lima, nā maka aniani a me nā lole pale.

-Inā pili, holoi koke me ka wai nui a ʻimi i ka lāʻau lapaʻau.

- Pono e hoʻolei ʻia ka wai a me ka ʻōpala e like me nā kānāwai kūloko.
