Isingeniso
I-2-bromo-3-chroo-5-(trifluoromethyl)pyridine iyinhlanganisela yemvelo enefomula ethi C6H2BrClF3N. Iwuketshezi oluphuzi ukuya kokuphaphathekile olunephunga elimnandi ekamelweni lokushisa.
Le nhlanganisela inezinhlobonhlobo zezicelo emkhakheni we-chemistry. Ingasetshenziswa njengesibulala-zinambuzane esimaphakathi ekwenzeni amakhemikhali ezolimo anjengama-insecticide, ama-fungicides kanye nama-herbicides. Ngaphezu kwalokho, ingasetshenziswa futhi ekuphenduleni kwe-organic synthesis njengento ebalulekile yokusetshenziswa.
I-2-bromo-3-chloro-5-(trifluoromethyl)pyridine ivamise ukukhiqizwa ngokuhlangana kwamakhemikhali. Indlela ethile ihlanganisa ukusabela kwe-3-chloro-5-(trifluoromethyl) pyridine ne-lithium bromide ku-ethanol ukuze kutholwe umkhiqizo ofunekayo.
Mayelana nokuphepha, lesi sithako siyacasula futhi siyagqwala. Ngesikhathi sokuphatha, izinyathelo zokuphepha ezifanele, njengokugqoka amagilavu okuzivikela kanye nezibuko, kufanele zithathwe ukuze kuqinisekiswe ukuthi umsebenzi wenziwa endaweni enomoya omuhle. Ngesikhathi esifanayo, gwema ukuthintana nesikhumba, amehlo kanye nomgudu wokuphefumula. Ngesikhathi sokugcina nokuphatha, izinqubo zokuphepha ezifanele kufanele zibhekwe ngokuqinile.
