Nhanganyaya
2,5-Difluorobenzaldehyde. Inotevera sumo kune hunhu hwayo, kushandiswa, nzira dzekugadzira uye ruzivo rwekuchengetedza:
Hunhu:
2,5-Difluorobenzaldehyde imvura isina ruvara kuenda kuchiedza yero ine mucherechedzo wakasimba wekutsva, hwema hunonhuwa patembiricha yekamuri. Hainyungudika mumvura asi inogona kunyungudika muorganic solvents senge ethanol, toluene, nezvimwe.
Shandisa:
2,5-Difluorobenzaldehyde ine huwandu hwakawanda hwekushandisa mune organic synthesis. Inogona kushandiswa seyakatangira yekubatanidza kweanonhuhwirira makomisheni, paraphthalenedione derivatives, uye bioactive mamorekuru. Inogonawo kushandiswa mukugadzirisa kwe organometallic complexes, high-performance coatings uye dhayi.
Nzira:
2,5-difluorobenzaldehyde inogona kugadzirirwa nekuita kwe benzaldehyde uye hydrogen fluoride. Kuita uku kunowanzoitwa pasi pemamiriro e acidic uye inogona kuwanikwa nekushandisa hydrofluoric acid senzvimbo yehydrogen fluoride.
Zvekuchengetedza
Kuchengetedza kwakakosha kunofanirwa kutorwa kana uchibata 2,5-difluorobenzaldehyde. Iine zvinogumbura paganda, maziso uye nzira yekufema. Makemikari ekudzivirira magirazi, magurovhosi uye zvipfeko zvekudzivirira zvinofanirwa kupfekwa uye kusangana kwakananga kunofanira kudzivirirwa. Kana ikapinda mumaziso ako kana paganda, sukurudza nekukurumidza nemvura yakawanda uye tsvaga kurapwa nekukurumidza. Panguva yekushanda, inofanira kuchengetedzwa kure nemoto uye kudzivirira utsi nemhute kudzivirira moto uye kuputika.
Ichi chiziviso chipfupi kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye2,5-difluorobenzaldehyde. Kana zvichidikanwa, ita shuwa kuti unonzwisisa uye nekutevera yakakodzera marabhoritari yekuchengetedza mirau uye nhungamiro usati wabata kana kushandisa.
