Hoʻolauna

ʻO ka 2,3-Difluorobenzoic acid kahi mea hoʻohui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka 2,3-difluorobenzoic acid:

ʻAno maikaʻi:

- Ke ʻano: paʻa kalakala kala ʻole

E hoʻohana:

Hanana:

- 2,3-Difluorobenzoic acid hiki ke hoʻomākaukau ʻia e ka fluorinating paraben. Hoʻohana mau ʻia nā mea hana fluorinating e like me hydrofluoric acid a me ferrous fluoride.

ʻIke palekana:

- Hōʻalo i ka pili ʻana me ka ʻili, nā maka, a me nā ʻāʻī, a holoi koke me ka wai nui inā pili.

- I ka mālama ʻana a me ka mālama ʻana, e pale i ka hoʻopili ʻana me nā oxidants a me nā ʻakika ikaika, a pale i ka ʻike ʻana i ka wela a me ke ahi.

- Inā pono, e kamaʻilio me ke kanaka loea no ka ʻike palekana.
