Nhanganyaya
2,6-Difluorobenzonitrile, inozivikanwawo se2,6-difluorobenzonitrile, inhengo yehupenyu. Iyi inotevera sumo kune chimiro chayo, kushandiswa, nzira yekugadzirira uye ruzivo rwekuchengetedza:
Hunhu:
- Kuonekwa: 2,6-Difluorobenzonitrile imvura isina ruvara kana chena crystal.
- Solubility: Soluble mune organic solvents.
Shandisa:
- 2,6-Difluorobenzonitrile inowanzoshandiswa sechinhu chakakosha chepakati mune organic synthesis, semuenzaniso sechinhu chekutanga chekugadzirwa kwemamwe makemikari.
Nzira:
- Nzira yekugadzirira ye 2,6-difluorobenzonitrile inonyanya kuwanikwa nekuita kwe 2,6-difluorobenzyl doro uye sodium cyanide muhupo hwe alkaline catalyst.
- Matanho chaiwo anosanganisira maitiro e2,6-difluorobenzyl doro ine sodium cyanide pasi pemamiriro ealkaline, inoteverwa neacidification kuwana 2,6-difluorobenzonitrile chigadzirwa.
Zvekuchengetedza
- 2,6-difluorobenzonitrile ine huturu hwakaderera, asi kutarisirwa kunofanira kutorwa kuti usapinda zvakananga neganda, maziso, uye nzira yekufema.
-Maitiro akakodzera ekuchengetedza uye michina yekudzivirira yakakodzera inofanirwa kuteverwa kana yashandiswa kana kuchengetwa.
- Kana komboni ikabatwa netsaona kana kufemerwa, inofanira kucheneswa kana kupinzwa mweya nekukasika uye kurapwa kunofanirwa kutsvagwa nekukasika.
