Hordhac
3-Acetylpyridine waa iskudhis organic ah. Kuwa soo socdaa waa hordhac qaar ka mid ah guryaha, isticmaalkooda, hababka diyaarinta iyo macluumaadka badbaadada 3-acetylpyridine:
Tayada:
Muuqaalka: 3-acetylpyridine waa mid aan midab lahayn ilaa kiristaalo huruud ah oo khafiif ah ama adag.
Solubility: 3-acetylpyridine waxay ku milmi kartaa dareerayaasha organic sida alkolada, ethers iyo ketones, iyo in yar oo ku milmay biyaha.
Waxyaabaha Kiimikada ah: 3-Acetylpyridine waa iskudhis aashito ah oo daciif ah oo ku jira biyaha.
Isticmaal:
Sida kiimiko isku-dhafan oo dabiici ah: 3-acetylpyridine waxaa caadi ahaan loo isticmaalaa fal-celinta synthesis organic sida dareere, reagent acylation, iyo kicin.
Waxaa loo isticmaalaa isku-dhafka dheeha: 3-acetylpyridine waxaa loo isticmaali karaa isku-dhafka midabada iyo midabada.
Habka:
Waxaa jira siyaabo badan oo loo diyaariyo 3-acetylpyridine, midda caadiga ahna waxaa lagu helaa falcelinta esterification ee stearic anhydride iyo pyridine. Guud ahaan, stearic anhydride iyo pyridine waxaa lagu falceliyaa dareere ah saamiga molar ee 1: 1, iyo kicinta aashitada xad-dhaafka ah ayaa lagu daraa inta lagu jiro falcelinta, iyo falcelin heerkulbeeg ah oo la xakameeyey ayaa la sameeyaa. Alaabta 3-acetylpyridine waxaa lagu helay crystallization, sifeynta, iyo qalajinta.
Macluumaadka Badbaadada:
3-Acetylpyridine waa in la kaydiyaa loona maareeyaa hab ka fogaanaya taabashada oxidants si looga fogaado dab ama qarax.
Raac hab-dhaqannada badbaadada shaybaadhka oo xidho qalabka ilaalinta habboon sida galoofyada, muraayadaha indhaha, iyo gooyada marka la isticmaalayo.
Ka fogow neefsashada, nuugista, ama taabashada maqaarka iyo indhaha, iskuna day inaad ka shaqeyso meel hawo fiican leh.
Waa in taxaddar la sameeyaa si looga fogaado boodhka iyo walxaha marka la qabanayo 3-acetylpyridine si loo yareeyo khatarta neefsashada.
