Hoʻolauna
ʻO 2,4-Bis(trifluoromethyl)bromobenzene kahi mea hoʻohuihui. Loaʻa iā ia nā waiwai penei:
ʻAno: ʻAʻohe kala i nā kristal melemele a i ʻole nā wai.
Solubility: Hiki ke hoʻoheheʻe ʻia e like me ka ethanol, acetone a me carbon disulfide.
ʻAʻole hiki ke hoʻoheheʻe ʻia: Insoluble in water.
ʻO 2,4-Bis(trifluoromethyl)bromobenzene ka hoʻohana nui ʻana i ka synthesis organik, a ʻo kāna mau noi nui penei:
E like me ka brominating agent: hiki ke hoʻohana ʻia i ka hoʻomākaukau ʻana i nā hydrocarbons halogenated, e like me ka bromoaromatic hydrocarbons.
Hiki ke hoʻohana ʻia ma ke ʻano he catalyst e komo i ka hana hoʻomaka o nā hopena radical manuahi.
ʻO ke ala no ka hoʻomākaukau ʻana i ka 2,4-bis(trifluoromethyl)bromobenzene penei:
Hoʻopili ʻia ka 2,4-bis(trifluoromethyl) benzene e ka bromination alcohol e hana i ka 2,4-bis(trifluoromethyl) bromobenzene.
Hōʻalo i ka hoʻopili pololei ʻana me ka ʻili a me nā maka, a pale i ka hoʻohu ʻana i ko lākou lepo a i ʻole ke kinoea.
Pono e ʻaʻahu ʻia nā lako pale kūpono, e like me nā mīkina lima lab, nā maka maka makamae palekana, a me ke kapa lole lab i ka wā o ka hana.
Hōʻalo i ka hoʻopili ʻana me nā mea kemika e like me nā mea ʻokiʻoki, nā ʻakika ikaika a i ʻole nā alkali e pale aku i nā hopena ʻino.
E hana ma kahi e hoʻoheheʻe maikaʻi ʻia e pale i ke kūkulu ʻia ʻana o nā kinoea ʻino.
E ʻoluʻolu e mālama pono ʻia nā lula pili i ka hana palekana i ka wā e hoʻohana ai i ka 2,4-bis(trifluoromethyl)bromobenzene, a e hoʻoponopono a hoʻopau iā ia e like me ke kūlana maoli.
