Intangiriro
3-Acetylpyridine ni ifumbire mvaruganda. Ibikurikira nintangiriro kuri bimwe mubintu, ikoreshwa, uburyo bwo gutegura namakuru yumutekano ya 3-acetylpyridine:
Ubwiza:
Kugaragara: 3-acetylpyridine nta ibara rifite ibara ryumuhondo ryoroshye cyangwa ibintu bikomeye.
Gukemura: 3-acetylpyridine irashonga mumashanyarazi kama nka alcool, ethers na ketone, kandi bigashonga gato mumazi.
Ibikoresho bya Shimi: 3-Acetylpyridine ni aside irike idafite aside irike mumazi.
Koresha:
Nka shimi ngengabihe ya chimique: 3-acetylpyridine ikoreshwa muburyo bwa synthesis organic reaction nka solvent, acylation reagent, na catalizator.
Ikoreshwa muguhindura irangi: 3-acetylpyridine irashobora gukoreshwa muguhuza amarangi na pigment.
Uburyo:
Hariho uburyo bwinshi bwo gutegura 3-acetylpyridine, kandi inzira isanzwe iboneka hamwe na esterification reaction ya stearic anhydride na pyridine. Muri rusange, anhydride ya stearic na pyridine bikorerwa mumashanyarazi ku kigereranyo cya 1: 1, hanyuma catisale irenze urugero ikongerwamo mugihe cyo kubyitwaramo, hanyuma hakorwa reaction ya esterifike igenzurwa na termodinamike. Igicuruzwa cya acetylpyridine 3 cyabonetse hakoreshejwe kristu, kuyungurura, no gukama.
Amakuru yumutekano:
3-Acetylpyridine igomba kubikwa no gukoreshwa muburyo bwirinda guhura na okiside kugirango wirinde umuriro cyangwa guturika.
Kurikiza imyitozo yumutekano wa laboratoire kandi wambare ibikoresho bibarinda nka gants, indorerwamo, na gown mugihe ukoresha.
Irinde guhumeka, kuribwa, cyangwa guhura nuruhu n'amaso, kandi ugerageze gukorera ahantu hafite umwuka mwiza.
Ugomba kwitondera kwirinda umukungugu nuduce mugihe ukoresha 3-acetylpyridine kugirango ugabanye ingaruka zo guhumeka.
