Isingeniso
I-3-Acetylpyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso kwezinye zezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-3-acetylpyridine:
Ikhwalithi:
Ukubukeka: I-3-acetylpyridine ayinambala kuya kumakristalu aphuzi akhanyayo noma okuqinile.
Ukunyibilika: I-3-acetylpyridine iyancibilika kuzincibilikisi zemvelo ezifana notshwala, ama-ether nama-ketone, futhi inyibilika kancane emanzini.
Izakhiwo Zamakhemikhali: I-3-Acetylpyridine iyinhlanganisela ene-asidi ebuthakathaka futhi ene-asidi emanzini.
Sebenzisa:
Njengekhemikhali ye-organic synthesis: I-3-acetylpyridine ivame ukusetshenziswa ekuphenduleni kwe-organic synthesis njenge-solvent, i-acylation reagent, ne-catalyst.
Isetshenziswa ekuhlanganiseni udayi: I-3-acetylpyridine ingasetshenziswa ekuhlanganiseni odayi nezingulube.
Indlela:
Kunezindlela eziningi zokulungiselela i-3-acetylpyridine, futhi evamile itholakala ngokusabela kwe-esterification ye-stearic anhydride ne-pyridine. Ngokuvamile, i-anhydride ye-stearic ne-pyridine iphendulwa ku-solvent ngesilinganiso se-molar ye-1: 1, futhi i-catalyst ye-asidi eyengeziwe yengezwa ngesikhathi sokusabela, futhi ukusabela kwe-esterification okulawulwa yi-thermodynamically kwenziwa. Umkhiqizo we-3-acetylpyridine utholwe nge-crystallization, ukuhlunga, nokomisa.
Ulwazi Lokuphepha:
I-3-Acetylpyridine kufanele igcinwe futhi iphathwe ngendlela egwema ukuthintana nama-oxidants ukugwema umlilo noma ukuqhuma.
Landela izinqubo zokuphepha zaselabhorethri futhi ugqoke izinto zokuzivikela ezifanele njengamagilavu, izibuko, nezingubo lapho usebenzisa.
Gwema ukuhogela, ukukungenisa, noma ukuthinta isikhumba namehlo, futhi uzame ukuhlinza endaweni engenawo umoya.
Kufanele kuqashelwe ukugwema uthuli nezinhlayiya lapho uphatha i-3-acetylpyridine ukuze unciphise ingozi yokuhogela.
