3-Chloro-4-fluorobenzyl bromide (CAS# 192702-01-5) Nhanganyaya
3-Chloro-4-fluorobenzyl bromide yakasimba ine hunhu hwemunhuwi hwakafanana nebromobenzene. Iine nzvimbo yakanyunguduka inenge 38-39 ° C. Uye nzvimbo yekubikira inenge 210-212 ° C. Pakupisa kwekamuri, inenge isingasviki mumvura, asi inonyunguduka mune zvakawanda zvinonyungudutsa.
Shandisa:
3-Chloro-4-fluorobenzyl bromide ine huwandu hwakawanda hwekushandisa mune organic synthesis. Iyo yakakosha yepakati yekugadzirira kwemamwe ma organic compounds, akadai semishonga, dhayi uye mishonga yezvipembenene. Inoshandiswawo mukugadzirira kwemurazvo retardants, photosensitive zvinhu uye resin modifiers.
Nzira:
3-Chloro-4-fluorobenzyl bromide inowanzowanikwa nekuita bromobenzene ne tert-butyl magnesium bromide. Kutanga, tert-butylmagnesium bromide inobatwa nebromobenzene pane tembiricha yakaderera kuwana tert-butylphenylcarbinol. Zvadaro, neklorini uye fluorination, mapoka e-carbinol anogona kuchinjwa kuva chlorine uye fluorine, uye 3-Chloro-4-fluorobenzyl bromide inoumbwa. Pakupedzisira, chinangwa chigadzirwa chinogona kuwanikwa nekucheneswa ne distillation.
Zvekuchengetedza
Shandisa 3-Chloro-4-fluorobenzyl bromide nekutarisa kune chepfu uye kushatirwa. Inogona kukonzera kushatirwa kuhurongwa hwekufema, ganda uye maziso. Dzivisa kusangana neganda, maziso uye kufema turakiti panguva yekushanda. Pfekai midziyo yekudzivirira yakafanira, senge magirovhosi, magirazi uye nhovo dzechiso. Mukuwedzera, inofanira kuchengetwa munzvimbo inofefetera zvakanaka uye kudzivisa kusangana nezvinhu zvakadai semaoxidants akasimba. Kana akamedzwa kana kufemerwa, tsvaga kurapwa nekukurumidza. Ndapota verenga mirairo yekuchengetedza zvigadzirwa zvakanyatsonaka usati washandisa.
