but-3-yn-2-one (CAS # 1423-60-5) introduction
3-butyne-2-ib. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, lub hom phiaj, kev tsim khoom, thiab cov ntaub ntawv kev nyab xeeb:
xwm:
-Cov tsos mob: 3-Butyn-2-ib qho yog xim tsis muaj xim rau lub teeb daj.
-Odor: Nws muaj cov ntxhiab tsw zoo ib yam li cawv thiab txiv hmab txiv ntoo.
-Solubility: soluble nyob rau hauv feem ntau cov organic solvents xws li cawv thiab ethers.
Lub hom phiaj:
-3-butyne-2-one yog dav siv nyob rau hauv cov organic synthesis. Nws tuaj yeem siv los ua cov khoom siv raw, catalyst, thiab hnyav rau tshuaj lom neeg cov tshuaj tiv thaiv, thiab tuaj yeem koom nrog ntau yam kev cuam tshuam cov organic synthesis, xws li kev hloov pauv nucleophilic thiab kev sib txuas lus.
Txoj kev tsim khoom:
-Ib txoj kev npaj 3-butyne-2-ib qho yog los ntawm cov tshuaj tiv thaiv ntawm acetone nrog propargyl cawv. Ua ntej, acetone reacted nrog ntau tshaj sodium hydroxide kom tau txais sodium acetate, uas yog ces reacted nrog propargyl cawv nyob rau hauv ib tug oxygen collector los tsim 3-butyne-2-one.
-Muaj ntau lwm txoj hauv kev los tsim 3-butyne-2-ib qho, xws li kev sib cais thiab ntxuav cov khoom siv ntuj tsim, siv cov txheej txheem tshuaj synthesis, thiab lwm yam.
Cov ntaub ntawv kev ruaj ntseg:
-3-Butyn-2-ib qho ua rau lub qhov muag, tawv nqaij, thiab ua pa, thiab yuav tsum tau muab yaug nrog dej tam sim ntawd.
-Tsis txhob sib cuag nrog cov oxidants muaj zog, muaj zog acids, thiab cov hauv paus muaj zog los tiv thaiv kev phom sij txaus ntshai.
-Thaum siv 3-butyne-2-one, cov hnab looj tes tiv thaiv tshuaj, tsom iav, thiab lub npog ntsej muag yuav tsum hnav kom ntseeg tau tias muaj cua zoo.
Cov no yog cov lus qhia yooj yim txog cov khoom, kev siv, kev npaj, thiab cov ntaub ntawv kev nyab xeeb ntawm 3-butyne-2-one. Thaum siv thiab tuav cov khoom sib xyaw no, thov nco ntsoov ua raws li cov txheej txheem kev nyab xeeb thiab xa mus rau cov ntaub ntawv kev nyab xeeb uas cuam tshuam thiab Blue Book of Chemical Substances.
