Okwu mmalite
3-Chloro-4-methylpyridine bụ ngwakọta organic. Njirimara ya bụ ndị a:
1. Ọdịdị:3-chloro-4-methylpyridinebụ mmiri mmiri edo edo enweghị agba.
2. Njupụta: 1.119 g/cm³
4. Solubility: 3-chloro-4-methylpyridine bụ soluble na ọtụtụ ihe mgbaze organic na mmiri na-adịghị ike.
Isi ojiji nke 3-chloro-4-methylpyridine bụ ndị a:
1. Nkwekọrịta nke mgbagwoju metal mgbanwe: Ọ bụ ihe dị mkpa etiti eji na nhazi kemịkalụ maka njikọ nke amino alcohols, amino alkates, na ndị ọzọ nitrogen heterocyclic ogige.
2. Pesticide intermediates: 3-chloro-4-methylpyridine nwere ike iji dị ka etiti na ụfọdụ ụmụ ahụhụ na ahịhịa.
Usoro maka ịkwadebe 3-chloro-4-methylpyridine na-agụnyekarị usoro ndị a:
1. Mmeghachi omume nitroation nke pyridine: pyridine na-emeghachi omume na nitric acid na sulfuric acid gbadoro anya iji nweta 3-nitropyridine.
2. Mbelata mmeghachi omume: 3-nitropyridine na-emeghachi omume na oke nke sulfoxide na ndị na-ebelata ihe (dị ka zinc ntụ ntụ) iji nweta 3-aminopyridine.
3. Chlorination mmeghachi omume: 3-aminopyridine na-emeghachi omume na thionyl chloride iji nweta 3-chloro-4-methylpyridine.
Ozi nchekwa dị mkpa nke 3-chloro-4-methylpyridine bụ nke a:
1. Nhụta: Nwere ike inwe mmeghachi omume nfụkasị ahụ nye ụfọdụ ndị mmadụ.
2. Iwe: nwere ike inwe mmetụta na-akpasu iwe na anya, usoro iku ume na akpụkpọ ahụ.
3. Nsi: Ọ na-egbu egbu nye ahụike mmadụ ma ga-agbaso usoro ọrụ nchekwa kwesịrị ekwesị.
4. Nchekwa: Ekwesịrị ịchekwa ya n'ime akpa ikuku, pụọ na mgbanye ọkụ na oxidants, na ikuku na kọntaktị.
Mgbe ị na-eji 3-chloro-4-methylpyridine, soro usoro nchekwa dị mkpa dị ka iyi akwa anya, uwe aka na uwe nchebe, wee hụ na a na-arụ ya na mpaghara ikuku nke ọma. Ọ bụrụ na kọntaktị na mberede ma ọ bụ iku ume, chọọ nlekọta ahụike ozugbo wee gosi dọkịta gị mpempe akwụkwọ nchekwa nchekwa ngwaahịa.
