Hoʻolauna
He pūhui mea ola ia me ke ʻano kemika C7H3BrF4. He wai waihoʻoluʻu ʻole a ʻeleʻele ʻeleʻele me kahi ʻala kūikawā ma ka lumi wela.
ʻAno:
1. wahi hehee:-33 ℃
2. Puni paila: 147-149 ℃
3. mānoanoa: 1.889g/cm³
4. Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka ether, ethanol a me dichloromethane, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.
E hoʻohana:
Hoʻohana nui ʻia ia ma ke ʻano he waena i ka synthesis organik. Hoʻohana maʻamau ia i ka synthesis lāʻau, catalysis chemical a me nā mea kūlohelohe, e like me benzopyrazolones, cyclic macrocyclization, organic photoelectric material synthesis, etc.
Kaʻina hoʻomākaukau:
ʻO ke ʻano o ka hoʻomākaukau ʻana o ka calcium ma o ka hopena o ka bromobenzene a me trifluorotoluene ma lalo o nā kūlana kūpono. ʻO ka mea maʻamau, hana ka bromobenzene me ka trifluorotoluene i mua o ka pauda keleawe a i ʻole ke kīʻaha ma lalo o ka hoʻomehana ʻana e hana i ka fluorotoluene.
ʻIke palekana:
He mea hoʻonāukiuki a pono e pale i ka pilina pololei me kaʻili a me nā maka. Pono e ʻaʻahu ʻia nā mea pale pilikino e like me nā mīkina lima pale, nā maka aniani a me nā lole pale i ka wā o ka hoʻohana ʻana a me ka lawelawe ʻana. E hōʻalo i ka hoʻohu ʻana i kona mau mahu a e hoʻopaʻa pono i ka hana ʻana ma kahi wahi maikaʻi. Eia kekahi, pono e mālama ʻia i loko o kahi pahu i hoʻopaʻa ʻia, mai kahi wela a me nā kumu ahi. I ka hoʻohana ʻana a i ʻole ka hoʻopau ʻana, e ʻoluʻolu e hahai i nā kaʻina hana palekana pili. Inā loaʻa kahi leak, pono e lawe ʻia nā hana hoʻomaʻemaʻe kūpono. Inā pono, pono e kūkākūkā i kahi loea.
