Kutanga kwe2-Bromofluorobenzene

2022-06-22
2-Bromofluorobenzene imhando ye organic matter, kemikari formula iC6H4BrF, nhamba yeCAS yekunyoresa 1072-85-1, inonyanya kushandiswa mukugadzirira nekugadzira mishonga, mishonga yekuuraya zvipembenene, liquid crystal material intermediates, synthesis of o-fluorobromobenzene is transparentless colorless. mvura inogadziriswa neUIVCHEM tekinoroji.


Bhodhoro reaction rinoshanduka kuita yakavakidzana fluoro aniline uye hydrobromic acid kusanganisa, kupisa kunoburitsa huwandu hukuru hwepepuru yakasimba kunaya, tembiricha yepamusoro ye60 â, maminetsi mashanu, kurunga ice munyu - 10 â pazasi, wedzera sodium nitrite. mhinduro inodonhedza uye kupisa kuburitsa maitiro, zvinhu zvinwiwa zvishoma nezvishoma zvichiva orenji kujekesa, kudonha kubva pamaminitsi makumi mana, kudonha kupisa kwemaminetsi gumi mushure mekujoinha carbamide, kutonhora, Isa cuprous bromide, hydrobromic acid, mvura uye Chemicalbook yekugeza mafuta mubhodhoro rekuita ne distillation. mudziyo, uchidziya kusvika 120 ~ 130â, chiutsi chemvura, tembiricha yemukati inenge 105â apo mvura inopfungaira ichibuda, yakatanga kudonhedza inorema nitrogen munyu, panguva ino kune huwandu hukuru hwemabhuru, kudzora kudonha kukurumidza. kuchengetedza iyo distillation mamiriro, iva nechokwadi chekuti inogadzirwa o-fluorobromobenzene inokurumidza kuitwa nemhepo yemvura. Mushure memaminitsi makumi mashanu ekudonha, mupfu kune mamwe maminetsi mashanu kumisa distillation. Kuparadzanisa mafuta, geza nemvura yakanyungudutswa yemunyu, sefa mafuta ekuyera mvura 0.04%, tora 2-Bromofluorobenzene.
