Nhanganyaya
Iyo organic compound ine kemikari formula yeC6H5ClFN. Iyi inotevera tsananguro yezvivakwa, mashandisiro, kugadzirira uye kuchengetedza ruzivo rwekomboni:
Zvakasikwa:
-Kutaridzika: Iyo isina ruvara kune yakapenya yero mvura.
-Poindi yekubikira: inenge 126-127°C.
-Density: inenge 1.36g/cm³.
-Solubility: Soluble mune zvakawanda organic solvents, akadai ethanol, ether uye dimethylformamide.
Shandisa:
-inoshandiswa zvakanyanya seyepakati mune organic synthesis uye inogona kushandiswa kugadzira mamwe organic makomisheni.
-Inogonawo kushandiswa sechinhu chekutanga chekugadzirwa kwezvinodhaka, pesticide synthesis uye dhayi synthesis.
Kugadzirira nzira:
-kana inogona kugadzirirwa nehalogenation reaction yepyridine. Kutanga, pyridine uye acetic acid inopinda chlorination reaction kuti ibudise 2-chloropyridine. Iyo 2-chloropyridine inozoshandurwa kuita 2-chloro-3-fluoropyridine ne fluorination reaction. Pakupedzisira, 2-chloro-3-fluoropyridine yaive methylated uchishandisa methylation reaction.
Zvekuchengetedza
-mushonga unogumbura unogona kutsamwisa maziso neganda.
-Panguva yekushandiswa nekubata, matanho akakodzera ekuchengetedza anofanirwa kutorwa, kusanganisira kupfeka magirazi ekudzivirira uye magurovhosi.
-Dzivisa kufema mhute yekomboni uye ona kuti inoshandiswa munzvimbo ine mhepo yakanaka.
-Paunenge uchichengeta uye uchibata, chengetedza kure nemoto uye oxidizing agents kudzivirira njodzi yemoto uye kuputika.
-Panguva yekushandiswa, kutarisisa kunofanirwa kubhadharwa kuenderana neakakodzera kuchengetedza maitiro maitiro uye mirau.
