Nhanganyaya
2-bromo-3-chroo-5-(trifluoromethyl)pyridine is an organic compound ine formula C6H2BrClF3N. Imvura isina ruvara kune yakachenuruka yero uye inonhuwa zvinopisa patembiricha.
Ichi chikamu chine huwandu hwakawanda hwekushandisa mumunda wekemikari. Inogona kushandiswa semushonga wepakati pekugadzira makemikari ekurima senge zvipembenene, fungicides uye herbicides. Uye zvakare, inogona zvakare kushandiswa mune organic synthesis maitiro seyakakosha mbishi zvinhu.
Iyo 2-bromo-3-chloro-5-(trifluoromethyl)pyridine inowanzo gadzirwa nemakemikari synthesis. Imwe nzira inosanganisira kuita 3-chloro-5-(trifluoromethyl) pyridine ine lithium bromide mu ethanol kuti uwane chigadzirwa chaunoda.
Panyaya yekuchengeteka, komisheni iyi inoshatirisa uye inoparadza. Panguva yekubata, matanho ekuchengetedza akakodzera, akadai sekupfeka magirovhosi ekudzivirira uye magirazi, anofanira kutorwa kuti ave nechokwadi chekuti kuvhiyiwa kunoitwa munzvimbo ine mhepo inofefetera. Panguva imwecheteyo, dzivisa kusangana neganda, maziso uye nzira yekufema. Panguva yekuchengetedza uye kubata, maitiro akakodzera ekuchengetedza anofanirwa kunyatsocherechedzwa.
