Intshayelelo
I-3-Acetylpyridine i-organic compound. Oku kulandelayo kukwazisa kwezinye iipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-3-acetylpyridine:
Umgangatho:
Imbonakalo: I-3-acetylpyridine ayinambala ukuya kwiikristale ezikhanyayo ezityheli okanye izinto eziqinileyo.
I-Solubility: I-3-acetylpyridine iyanyibilika kwii-solvents eziphilayo ezifana ne-alcohol, i-ethers kunye ne-ketones, kwaye i-soluble kancinane emanzini.
Iipropati zeMichiza: I-3-Acetylpyridine yikhompawundi eneasidi ebuthathaka eneasidi emanzini.
Sebenzisa:
Njengekhemikhali ye-organic synthesis: I-3-acetylpyridine isetyenziswa ngokuqhelekileyo kwiimpendulo ze-organic synthesis njenge-solvent, i-acylation reagent, kunye ne-catalyst.
Isetyenziswe kwi-synthesis yedayi: i-3-acetylpyridine ingasetyenziselwa ukuhlanganiswa kwedayi kunye ne-pigments.
Indlela:
Zininzi iindlela zokulungisa i-3-acetylpyridine, kwaye enye eqhelekileyo ifunyanwa ngokusabela kwe-esterification ye-stearic anhydride kunye ne-pyridine. Ngokuqhelekileyo, i-anhydride ye-stearic kunye ne-pyridine iphendulwa kwi-solvent kwi-molar ratio ye-1: 1, kwaye i-catalyst ye-asidi engaphezulu yongezwa ngexesha lokuphendula, kwaye i-reaction esterification elawulwa yi-thermodynamically yenziwa. Imveliso ye-3-acetylpyridine yafunyanwa nge-crystallization, filtration, kunye nokomisa.
Ulwazi ngoKhuseleko:
I-3-Acetylpyridine kufuneka igcinwe kwaye iphathwe ngendlela ethintela ukudibana nee-oxidants ukuphepha umlilo okanye ukuqhuma.
Landela iindlela zokhuseleko lwaselabhoratri kwaye unxibe izixhobo ezifanelekileyo zokhuseleko ezifana neeglavu, iiglasi, kunye neegawuni xa usebenzisa.
Kuphephe ukuphefumla umoya, ukuseza, okanye ukudibana nolusu namehlo, kwaye zama ukusebenza kwindawo engena umoya.
Ukunyamekela kufuneka kuthathwe ukuphepha uthuli kunye neengqungquthela xa ubamba i-3-acetylpyridine ukunciphisa umngcipheko wokuphefumula.
