3-choro-5- (trifluoromethyl) pyridine bụ ngwakọta organic nwere usoro kemịkal C≡H₂ ClFΛ N. Nke a bụ nkọwa nke ọdịdị, ojiji, nkwadebe na ozi nchekwa nke 3-choro-5- (trifluoromethyl) pyridine:
Ọdịdị:
-Njupụta: 1.578 g/mL
- Ebe esi mmiri: 79-82 ℃
- Ebe mgbaze: -52.5 ℃
-Solubility: Soluble na organic solvents dị ka ethanol, ether na dichloromethane, ubé soluble na mmiri.
Jiri:
-Dị ka reagents na intermediates na organic njikọ, eji na njikọ nke pesticides, ọgwụ na ndị ọzọ organic ogige.
-Maka nyocha na ngalaba ọgwụ, dị ka na njikọ nke ọgwụ mgbochi ọrịa cancer na biomarkers.
Ụzọ nkwadebe:
Enwere ike ịkwadebe 3-chloro-5- (trifluoromethyl) pyridine site na ụzọ abụọ a:
1. Iji pyridine dị ka akụrụngwa, a na-eme mmeghachi omume chlorination na ọnụnọ hydrochloric acid, mgbe ahụ, a na-eme mmeghachi omume trifluoromethylation na ọnụnọ sodium trifluoromethylate.
2. Iji 3-picolinic acid dị ka ihe eji eme ihe, a na-eme mmeghachi omume chlorination n'ihu thionyl chloride, mgbe ahụ, a na-eme mmeghachi omume trifluoromethylation n'ihu trifluoromethyl mercaptan.
Ozi nchekwa:
- 3-chloro-5- (trifluoromethyl) pyridine na-akpasu iwe ma nwee ike ime ka mgbakasị ahụ na kọntaktị na akpụkpọ ahụ na anya. Ọ dị mkpa iyi ihe nchebe kwesịrị ekwesị mgbe ị na-eji ya, dị ka iyi enyo nchebe, uwe aka na uwe nchebe.
- Zere ikuru uzuoku ya ma hụ na a na-arụ ọrụ ahụ na ebe ikuku na-ekpo ọkụ.
- Mgbe ị na-echekwa ya, debe ya n'ime akpa mkpuchi, pụọ na ọkụ na ihe ndị na-emepụta ihe.
-Mgbe ị na-ekpofu ihe mkpofu, gwọọ ma tụfuo ya dịka iwu obodo siri dị.
Biko lelee mpempe akwụkwọ data nchekwa dị mkpa (SDS) maka ozi nchekwa zuru oke.
