3-Chloro-4-fluorobenzyl bromide (CAS# 192702-01-5) Hordhac
3-Chloro-4-fluorobenzyl bromide waa mid adag oo leh ur sifo ah oo la mid ah bromobenzene. Waxay leedahay bar dhalaalaysa oo ku saabsan 38-39 ° C. Iyo barta karkaraya ee ku saabsan 210-212 ° C. heerkulka qolka, waxay ku dhowdahay in aan lagu milmi karin biyaha, laakiin ku milma inta badan dareerayaasha organic.
Isticmaal:
3-Chloro-4-fluorobenzyl bromide waxay leedahay codsiyo badan oo kala duwan oo ku saabsan isku dhafka dabiiciga ah. Waa dhexdhexaad muhiim ah oo loogu talagalay diyaarinta xeryahooda kale ee dabiiciga ah, sida daroogooyinka, midabada iyo sunta cayayaanka. Waxa kale oo loo isticmaalaa diyaarinta ololka retardants, qalabka sawir-qaadista iyo beddelayaasha resin.
Habka:
3-Chloro-4-fluorobenzyl bromide guud ahaan waxaa lagu helaa ka falcelinta bromobenzene oo leh tert-butyl magnesium bromide. Marka hore, tert-butylmagnesium bromide waxaa lagu falceliyaa bromobenzene heerkulka hooseeya si loo helo tert-butylphenylcarbinol. Kadib, koloriination iyo fluorination, kooxaha karbinol waxaa loo rogi karaa koloriin iyo fluorine, waxaana la sameeyay 3-Chloro-4-fluorobenzyl bromide. Ugu dambeyntii, badeecada la beegsanayo waxaa lagu heli karaa nadiifin by distillation.
Macluumaadka Badbaadada:
Isticmaal 3-Chloro-4-fluorobenzyl bromide adigoo fiiro gaar ah u leh sunta iyo xanaaqa. Waxay u keeni kartaa cuncun habdhiska neefsiga, maqaarka iyo indhaha. Ka fogow taabashada maqaarka, indhaha iyo mareenka neef-mareenka xilliga shaqada. Xiro qalabka ilaalinta habboon, sida galoofyada, muraayadaha indhaha iyo gaashaanka wejiga. Intaa waxaa dheer, waa in lagu kaydiyaa meel hawo fiican leh oo laga fogaado xidhiidhka walxaha sida oksidayaasha xooggan. Haddii la liqo ama la nuugo, isla markiiba raadso daryeel caafimaad. Fadlan si taxadar leh u akhri tilmaamaha badbaadada alaabta ka hor intaanad isticmaalin.
