Nhanganyaya
2,5-Difluorobenzyl bromide. Iyi inotevera sumo kune chimiro chayo, kushandiswa, nzira yekugadzirira uye ruzivo rwekuchengetedza:
Hunhu:
Kuonekwa: 2,5-benzyl difluorobromide imvura isina ruvara kana kuti yero zvishoma.
Density: 1.74-1.76 g/cm³.
Solubility: Inonyungudika muorganic solvents senge madoro, ether uye asiri-polar solvents.
Shandisa:
2,5-difluorobenzyl bromide inonyanya kushandiswa seyepakati uye mbishi zvinhu musanganiswa mune organic synthesis.
Mune organic synthesis, inowanzoshandiswa kuita fluorination yeolefins uye inosarudza fluorination yeanonhuwirira makomisheni.
Nzira:
Kugadzirira kwe2,5-difluorobenzyl bromide kunogona kuitwa nematanho anotevera:
Kutanga, 2,5-dibromobenzyl uye trifluoroacetic acid inobatwa uye inogadziriswa mugasi condensate kana mvura kugadzirira 2,5-difluorobenzylbromide mhinduro.
Iyo yakachena 2,5-difluorobenzyl bromide chigadzirwa chinobva chanatswa, kupepetwa, uye kuomeswa.
Zvekuchengetedza
2,5-difluorobenzyl bromide ine humwe huturu, uye matanho ekuchengetedza anofanirwa kutorwa paunenge uchiishandisa, kudzivirira kusangana neganda, maziso uye nzira yekufema.
Panguva yekushandiswa nekugadzirira, midziyo yekudzivirira yakakodzera senge magirovhosi emurabhoritari, magogi, uye masks ekudzivirira zvinofanirwa kupihwa.
Inofanirwa kushandirwa munzvimbo ine mhepo inofefetera zvakanaka uye kudzivirira kusangana nezvinobatidza moto uye oxidants.
Paunenge uchichengeta, 2,5-difluorobenzyl bromide inofanira kuchengetwa munzvimbo inotonhorera, yakaoma uye ine mhepo, kure nemoto uye zvinopisa.
Ndokumbira uteedzere kwakakodzera marabhoritari maitiro uye nhungamiro yekubata zvakachengeteka paunenge uchishandisa nekubata 2,5-difluorobenzyl bromide.
