Hoʻolauna
He mea hoʻohuihui olaola, ʻano kemika no C7H3BrF4, ʻaʻole waihoʻoluʻu kona helehelena a i ʻole ka wai melemele māmā. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
-Density: approx. 1.894g/cm³
-Ka helu heheʻe: ma kahi o -23°C
-Pila paila: ma kahi o 166-168°C
-Solubility: Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe maʻamau, e like me ka ethanol, dimethylformamide a me dichloromethane.
E hoʻohana:
Hoʻohana nui ʻia ia ma ke kahua o ka synthesis organik ma ke ʻano he mea maka no ka synthesis o nā ʻano lāʻau lapaʻau a me nā waena. Hoʻohana maʻamau ia i nā hopena fluorination a me nā hopena alkylation. Eia kekahi, hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā pesticides, nā mea photoelectric a me nā mea hoʻohui ʻē aʻe.
Kaʻina hoʻomākaukau:
Nui nā ʻano hana synthesis o ka phosphor, a loaʻa kahi ala maʻamau e ka hopena o 4-bromo-fluorobenzene a me ke kinoea fluorine i mua o kahi catalyst. Pono ke ʻano hoʻomākaukau kūikawā i kekahi mau hana a me nā kūlana.
ʻIke palekana:
-ʻoi aku ka palekana ma lalo o nā kūlana hoʻohana maʻamau. Eia nō naʻe, pono e hoʻohana pono ʻia kekahi mea kemika a hahai i nā kaʻina hana palekana.
-E hoʻohana i nā mea pale kūpono e like me nā mīkina lima pale, nā maka aniani a me nā pale pale i ka wā e hoʻohana ai.
-E hōʻalo i ka hanu ʻana i kona mau mahu a i ʻole pili me ka ʻili a me nā maka.
-I ka mālama ʻana a me ka mālama ʻana, e pale i ka hoʻopili ʻana me nā oxidants ikaika a me nā kūlana wela kiʻekiʻe.
-Ina pilikia a hoohana hewa paha, e imi koke i ka lapaau.
