Nhanganyaya
3,5-difluorobenzaldehyde isanganiswa ine organic formula C7H4F2O. Iyi inotevera tsananguro yezvivakwa, mashandisiro, kugadzirira uye kuchengetedza ruzivo rwekomboni:
Properties: 3,5-difluorobenzaldehyde haina ruvara kune yero yakasimba uye yakakosha phenone hwema. Iine density ye1.383g/cm³, nzvimbo yekunyunguduka inosvika 48-52°C, uye painofashaira inosvika 176-177°C. 3,5-difluorobenzaldehyde hainyungudike mumvura, asi inonyungudika muorganic solvents senge ethanol, ether, uye benzene.
Zvishandiso: 3,5-difluorobenzaldehyde inowanzoshandiswa sepakati mune organic synthesis. Inogona kushandiswa kugadzira akasiyana fluorine-ine organic komisheni, kunyanya kune kemikari maitiro anounza maatomu efluorine muma organic mamorekuru. Uye zvakare, inogona zvakare kushandiswa seyakagadzirwa yepakati yemishonga, mishonga yezvipembenene uye dhayi.
nzira yekugadzirira: nzira yekugadzirira ye3,5-difluorobenzaldehyde inogona kuwanikwa kuburikidza nekuita 3,5-difluorobenzyl methanol ne acid aldehyde reagent (yakadai se trichloroformic acid, nezvimwewo). Nzira dzakananga dzekugadzira dzinogona kureva Organic Synthesis Handbook nemamwe mabhuku ane hukama.
Ruzivo rwekuchengetedza: 3,5-difluorobenzaldehyde ikemikari uye inoda kushandiswa zvakachengeteka. Inotsamwisa uye inoita ngura uye inogona kukuvadza maziso, ganda nekufema. Midziyo yekuzvidzivirira yakafanira senge magogi, magirovhosi nenhoo yekumeso inofanirwa kupfekwa panguva yekushandiswa. Tevedzera maitirwo ekuchengetedza murabhoritari uye chengetedza, bata uye urase mukomboni nemazvo. Muchiitiko chekusangana netsaona kana kunwa, tsvaga kurapwa nekukurumidza uye upe ruzivo rwakakodzera kuna chiremba.
