2-Cyano-5-methylpyridine (CAS# 1620-77-5)

Ndi organic pawiri ndi mankhwala chilinganizo cha C8H7N ndi structural chilinganizo cha CH3-C5H3N(CN). Zotsatirazi ndizofotokozera za katundu, ntchito, njira zopangira ndi chitetezo: Chilengedwe:
1. Maonekedwe: madzi opanda mtundu mpaka achikasu.
2. Malo osungunuka:-11 ℃.
3. Malo otentha: 207-210 ℃.
4. Kusungunuka: Kusungunuka pang'ono m'madzi, kusungunuka mu zosungunulira za organic monga ma alcohols ndi ethers.
1. Amagwiritsidwa ntchito kwambiri mu kaphatikizidwe organic, angagwiritsidwe ntchito ngati reagent, wapakatikati kapena chothandizira nawo zosiyanasiyana zimachitikira, monga C-C chomangira mapangidwe anachita, cyanide anachita.
2. Ikhoza kutenga nawo mbali mu kaphatikizidwe ka pyridine, pyridine ketones ndi mankhwala ena achilengedwe.
3. Angagwiritsidwenso ntchito mu mankhwala ophera tizilombo, mankhwala ndi zina.

Njira:
Itha kukonzedwa ndi njira yopangira iyi:
1. Pyridine imakhudzidwa ndi methyl acetic anhydride kupanga 5-methyl pyridine.
2. Pangani 5-picoline ndi sodium cyanide pansi pamikhalidwe yamchere kuti mupange a.

Zambiri Zachitetezo:
1. Over ndi organic mankhwala, pali kawopsedwe, chonde tsatirani zasayansi njira chitetezo, kulabadira zodzitetezera.
2. Pewani kukhudzana ndi khungu, maso, ndi zina zotero. Ngati pali kukhudzana, sukani mwamsanga ndi madzi ambiri. Ngati pali vuto lililonse, chonde pitani kuchipatala.
3. Posungira ndi kusamalira, chonde pewani kutentha kwakukulu, magwero a moto, ndikusunga malo opangira mpweya wabwino.
4. Madzi otayira amayenera kutayidwa motsatira malamulo a mderalo pofuna kupewa kuwononga chilengedwe.

Chonde dziwani kuti kagwiritsidwe ntchito ndi kasamalidwe ka mankhwala kuyenera kutsata malamulo oyenera komanso njira zoyendetsera ntchito zotetezeka, ndikutsatira malangizo oyenera a labotale.
