Hoʻolauna

He pūhui mea ola ia me ke ʻano kemika C6H7FN2. ʻO kēia ka hoʻolauna ʻana i kekahi o kāna mau waiwai, hoʻohana, nā ʻano a me nā ʻike palekana.

 

ʻAno:

1. Nani: ʻAʻole waihoʻoluʻu a ʻeleʻele melemele crystalline paʻa.

2. Ka helu hehee: ma kahi o 82-85 ℃.

3. Kohu paila: Ma kahi o 219-221 ℃.

4. Solubility: Hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe organik e like me ka ethanol, ether a me dichloromethane.

 

E hoʻohana:

Hoʻohana nui ʻia ia ma ke ʻano he waena i ka synthesis organik. Hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā ʻano mea like ʻole, e like me nā lāʻau lapaʻau, pesticides, dyes a me nā ligands. Loaʻa iā ia ka waiwai hoʻohana pono ma ke kahua o ka lāʻau lapaʻau.

 

Hanana:

loaʻa maʻamau ma ka hana ʻana i ka pyridine me ka fluorinating reagent a me ka amino reagent no ka hopena methylation. Hiki ke hoʻololi a hoʻomaikaʻi ʻia ke ʻano synthesis kikoʻī e like me nā pono maoli.

 

ʻIke palekana:

1. He mea hoʻonāukiuki paha i nā maka, ka ʻili a me ka ʻōnaehana hanu. Pono e hoʻohana pono e pale aku i ka pilina.

2. E hoʻohana i nā mea pale kūpono e like me nā mīkina lima, nā aniani palekana a me nā pale pale i ka wā o ka hana.

3. Hō'alo i ka ho'ohu 'ana i ka lepo, ka mahu a me ke kinoea. Pono e hoʻoheheʻe ʻia ka wahi hana.

4. Inā pili ʻole a hoʻohana hewa paha, pono e holoi koke a lapaʻau paha.
