Nhanganyaya
3,4-difluorotoluene is an organic compound ine kemikari formula C7H6F2. Imvura isina ruvara ine kunhuhwirira kwakakosha. Iyi inotevera rondedzero yakadzama yechimiro, kushandiswa, kugadzirira uye chengetedzo ruzivo rwe3,4-difluorotoluene:
Zvakasikwa:
-Kuonekwa: mvura isina ruvara
-Kuravira: Kunhuhwirira kwakakosha
-Kubikira nzvimbo: 96-97 ° C
-Density: 1.145g/cm³
-Solubility: Insoluble mumvura, soluble mune organic solvents
Shandisa:
-3,4-difluorotoluene inogona kushandiswa sechinhu chakakosha chepakati mune organic synthesis.
-Inogona kushandiswa kugadzira mishonga, dhayi, mishonga yezvipembenene nemamwe makemikari.
-Iyo inogona zvakare kushandiswa seyakagadzirwa zvinhu zvemagetsi zvinhu.
Nzira:
-3,4-difluorotoluene ine nzira dzakawanda dzekugadzirira, iyo inonyanya kuwanikwa inowanikwa nehydrogenation reduction reaction ye p-nitrotoluene. Matanho chaiwo ndeaya:
1. Kutanga, P-nitrotoluene inopindirana nesimbi yakawandisa diammonium sulfate kuwana p-nitrotoluene iron diammonium munyu.
2. Hydrogen inowedzerwa, uye p-nitrotoluene iron diammonium munyu inoiswa pasi pekuderedza maitiro muhupo hwesimbi inogadzirisa.
3. Pakupedzisira, 3,4-difluorotoluene yakacheneswa ne distillation.
Zvekuchengetedza
-3,4-difluorotoluene inowanzoonekwa seyakachengeteka pasi pemamiriro akajairwa ekushandiswa. Nekudaro, zvichiri kudikanwa kutevedzera nzira dzekuchengetedza dzakakodzera.
-Iyo mvura inopisa uye inofanira kudzivisa kusangana nemoto uye kupisa kwakanyanya.
-Magurovhosi ekudzivirira akakodzera, magirazi uye zvipfeko zvekudzivirira zvinokurudzirwa kushandiswa uye kubata.
-Gara kure nechikafu, mvura nekusvikirwa nevana.
-Muchiitiko chekusangana netsaona kana kumedza netsaona, tsvaga rubatsiro rwekurapa nekukurumidza uye ratidza chigadzirwa label kana mudziyo kune mutano wehutano.
