Hoʻolauna
ʻO ka 2,4-Difluorophenylacetic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka 2,4-difluorophenylacetic acid:
ʻAno maikaʻi:
- 2,4-Difluorophenylacetic acid he paʻa kala ʻole i ka melemele me kahi ʻala ʻala.
- He non-volatile i ka lumi wela a hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik e like me ka ethanol, acetone, ether, etc.
- He ʻakika palupalu hiki ke hoʻoheheʻe ʻia i loko o ka alkali.
E hoʻohana:
- Hiki ke hoʻohana ʻia ma ke ʻano he waena i nā kala a me nā mea hoʻonaninani no ka synthesis o nā kala a me nā uhi o nā waihoʻoluʻu kikoʻī a waiwai paha.
Hanana:
- Hiki ke loaʻa ka 2,4-Difluorophenylacetic acid ma ka hopena o ka phenylacetic acid me ka hydrogen fluoride a i ʻole ke kinoea fluorine. Pono pinepine nā kūlana hoʻololi i ka catalyst a me ka hoʻomalu wela kūpono.
ʻIke palekana:
- 2,4-Difluorophenylacetic acid he mea hoʻohana pono e hoʻohana palekana.
- I ka lawelawe ʻana, e pale i ka pili pono ʻana me ka ʻili a me nā maka, a e mālama pono i ka pale ʻana i ka ʻōpū hanu.
- I ka wā e mālama ai, pono e mālama ʻia i loko o kahi pahu paʻa i ka ea, ma kahi mamao aku i nā kumu ahi a me nā mea oxidants, a pale aku i ka pili ʻana me ka ea a me ka wai.
- Pono e hoʻolei ʻia ka ʻōpala e like me nā kānāwai kaiapuni a me nā lula, a ʻaʻole pono e hoʻolei wale ʻia.
