Nhanganyaya
2,3,5-Trifluoropyridine is an organic compound ine kemikari formula C5H2F3N. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:
Zvakasikwa:
2,3,5-Trifluoropyridine imvura isina ruvara uye inonhuwa. Iine density ye1.42 g/mL, kuvira kwe90-91°C, uye kunyungudika kwe -47°C. Iyo ine yakasimba hydrophobicity uye yakaoma kunyungudika mumvura, asi inogona kunyungudika mune zvakajairika organic solvents senge ethanol, acetone uye xylene.
Shandisa:
2,3,5-Trifluoropyridine inonyanya kushandiswa mumunda we organic synthesis. Seye inoshanda fluorination reagent, inogona kushandiswa mukuita fluorination, uye inowanzo shandiswa mukuita kwekuunza maatomu efluorine. Uye zvakare, inogona zvakare kushandiswa seyepakati pakubatanidzwa kwemishonga, mishonga yezvipembenene uye mamwe ma organic compounds.
Kugadzirira nzira:
2,3,5-Trifluoropyridine ine nzira dzakawanda dzekugadzirira, imwe yadzo inowanzoshandiswa kuwana nekuita 2,3, 5-trichloropyridine ne hydrofluoric acid. Munguva yekupindura, 2,3, 5-trichloropyridine inobatwa ne hydrofluoric acid mune yakakodzera solvent, uye kutaridzika kwekushisa uye pH kukosha kunodzorwa kuti pakupedzisira kuwana 2,3,5-Trifluoropyridine.
Zvekuchengetedza
Teerera kune matanho ekuchengetedza paunenge uchibata 2,3,5-Trifluoropyridine. Icho chinhu chinonhuwa chinonhuwa chinogona kukonzera kushatirwa kuganda, maziso uye kufema system. Naizvozvo, dzivisa kusangana zvakananga neganda nemeso paunenge uchishandisa, uye ita shuwa kushanda munzvimbo ine mhepo inofefetera. Panguva yekubata nekuchengetedza, zvinodikanwa kutora matanho ekudzivirira akakodzera uye kudzivirira kusangana neoxidizing agents uye yakasimba acids kudzivirira kuita kwengozi.
Pamusoro pezvo, pakushandisa chero makemikari, ndokumbirawo uteedzere nzira dzekushanda nemirairo yakakodzera, uye bvunza hutungamiriri hwehunyanzvi pazvinenge zvichidikanwa.
