【Physical and Chemical Properties】
Cov mis mos thiab cov qauv: Cov mis molecular ntawm 4-methylpyridine yog C6H7N, thiab nws cov qauv muaj rau lub nplhaib pyridine nrog ib pawg methyl (CH3) txuas rau ib qho ntawm cov pa roj carbon atoms.
Lub cev muaj zog: Nws yog cov kua uas tsis muaj xim uas tsis hloov pauv ntawm chav tsev kub thiab muaj qhov tsw qab ntxiag. Nws cov ntsiab lus melting yog li 2.4 degree thiab nws qhov kub ntawm 145 degree. Qhov ceev ntawm 4-methylpyridine yog li ntawm 0.957 g/mL (ntawm 25 degree ).
Solubility: 4-methylpyridine yog soluble hauv cov kuab tshuaj organic xws li dej, ethanol thiab ether, uas ua rau nws zoo soluble thiab haum rau ntau cov tshuaj tiv thaiv thiab kev lag luam.
Kev nyab xeeb: Raws li cov khoom siv tshuaj, 4-methylpyridine yog cov tshuaj toxicity tsawg, tab sis kev ntsuas kev nyab xeeb tsim nyog tseem yuav tsum tau ua kom tsis txhob muaj kev sib cuag thiab nqus pa vim tias nws tuaj yeem ua rau tuag tes tuag taw ntawm lub paj hlwb. Tsis tas li ntawd, nws yog flammable, yog li nws yuav tsum tau muab khaws cia thiab siv kom deb ntawm qhov hluav taws kub thiab cua sov.
【Application fields】
Kev lag luam kws tshuaj: 4-methylpyridine yog dav siv nyob rau hauv kev lag luam kws tshuaj raws li ib tug intermediate rau synthesis ntawm tej yam tshuaj, xws li isoniazid. Nws tseem yog cov khoom siv raw rau kev tsim cov tshuaj tiv thaiv xws li diphosphonium thiab diphosphonium.
Tshuaj tua kab: Hauv kev lag luam tshuaj tua kab, 4-methylpyridine tuaj yeem siv los tsim cov tshuaj tua kab los pab tswj cov kab tsuag qoob loo.
Dyes thiab roj hmab additives: Tsis tas li ntawd, 4-methylpyridine kuj tseem siv rau hauv kev tsim cov dyes thiab ua cov roj hmab ntxiv los txhim kho cov khoom ntawm cov roj hmab.
Synthetic resins: 4-methylpyridine kuj ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv hluavtaws, tshwj xeeb tshaj yog nyob rau hauv kev tsim khoom ntawm qee yam ntawm cov resins.
