Phenylacetylene (CAS # 536-74-3) qhia
zoo
Phenacetylene yog ib qho organic compound. Nov yog qee yam ntawm cov khoom ntawm phenylacetylene:
1. Lub cev muaj zog: Phenacetylene yog cov kua uas tsis muaj xim uas tsis muaj suab nrov ntawm chav tsev kub.
2. Cov khoom siv tshuaj: Phenylacetylene tuaj yeem ua rau muaj ntau yam kev cuam tshuam txog carbon-carbon triple bonds. Nws tuaj yeem dhau los ua cov tshuaj tiv thaiv ntxiv nrog halogens, xws li cov tshuaj tiv thaiv ntxiv nrog cov tshuaj chlorine los ua phenylacetylene dichloride. Phenacetylene tuaj yeem ua rau txo qis cov tshuaj tiv thaiv, reacting nrog hydrogen nyob rau hauv lub xub ntiag ntawm ib tug catalyst los tsim styrene. Phenylacetylene tseem tuaj yeem nqa tawm qhov hloov pauv ntawm ammonia reagents los tsim cov khoom hloov pauv sib xws.
3. Kev ruaj ntseg: Cov pa roj carbon-carbon triple daim ntawv cog lus ntawm phenylacetylene ua rau nws muaj qhov siab tsis txaus ntseeg. Nws yog ib qho tsis ruaj tsis khov thiab ua rau muaj kev cuam tshuam ntawm cov tshuaj polymerization. Phenacetylene kuj yog cov nplaim hluav taws kub heev thiab yuav tsum tau zam los ntawm kev sib cuag nrog cov oxidizing muaj zog thiab cov khoom siv hluav taws xob.
Cov no yog qee yam ntawm cov khoom tseem ceeb ntawm phenylacetylene, uas muaj cov txiaj ntsig tseem ceeb hauv kev tsim cov organic, cov ntaub ntawv tshawb fawb thiab lwm yam.
Cov ntaub ntawv kev nyab xeeb
Phenacetylene. Nov yog qee cov ntaub ntawv kev nyab xeeb txog phenylacetylene:
1. Toxicity: Phenylacetylene muaj qee yam toxicity thiab tuaj yeem nkag mus rau tib neeg lub cev los ntawm kev nqus pa, tiv tauj nrog daim tawv nqaij, lossis kev noj. Lub sij hawm ntev los yog muaj kev xav tau siab tuaj yeem ua rau muaj kev cuam tshuam tsis zoo rau lub ntsws, lub paj hlwb, thiab lub siab.
2. Kev tawg hluav taws: Phenylacetylene yog cov khoom siv hluav taws xob uas muaj peev xwm tsim tau cov khoom tawg nrog cov pa oxygen hauv huab cua. Cov nplaim taws qhib, qhov kub thiab txias, lossis qhov hluav taws kub tuaj yeem ua rau hluav taws kub lossis tawg. Kev sib cuag nrog cov khoom xws li oxidants thiab muaj zog acids yuav tsum zam.
3. Tsis txhob nqus pa: Phenylacetylene muaj cov ntxhiab tsw ntxhiab uas yuav ua rau kiv taub hau, tsaug zog, thiab ua pa tsis xis nyob. Kev ua pa zoo yuav tsum tau tswj xyuas thaum lub sijhawm ua haujlwm thiab kev nqus ncaj qha ntawm phenylacetylene vapors lossis gases yuav tsum zam.
4. Tiv tauj tiv thaiv: Thaum tuav cov tshuaj phenylacetylene, hnav cov hnab looj tes tiv thaiv, tsom iav thiab cov khaub ncaws tiv thaiv tsim nyog kom tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag.
5. Cia thiab tuav: Phenylacetylene yuav tsum muab cia rau hauv qhov chaw txias, qhov cua zoo, kom deb ntawm qhov hluav taws kub thiab qhib nplaim taws. Lub thawv yuav tsum tau kuaj xyuas kom tsis muaj mob ua ntej siv. Cov txheej txheem tuav yuav tsum ua raws li cov txheej txheem kev ua haujlwm nyab xeeb kom tsis txhob muaj hluav taws xob thiab hluav taws xob hluav taws xob.
Siv cov txheej txheem synthesis
Phenacetylene yog ib qho organic compound. Nws yog tsim los ntawm lub nplhaib benzene txuas nrog acetylene pawg (EtC≡CH).
Phenacetylene muaj ntau yam kev siv hauv cov organic synthesis. Nov yog qee qhov kev siv tseem ceeb:
Kev siv tshuaj tua kab: phenylacetylene yog ib qho tseem ceeb nruab nrab ntawm kev sib txuas ntawm qee cov tshuaj tua kab uas siv ntau, xws li dichlor.
Kev siv kho qhov muag: Phenylacetylene tuaj yeem siv rau hauv cov tshuaj tiv thaiv photopolymerization, xws li kev npaj cov ntaub ntawv photochromic, cov ntaub ntawv photoresistive, thiab cov ntaub ntawv photoluminescent.
Cov txheej txheem synthesis ntawm phenylacetylene hauv cov chaw soj nstuam thiab kev lag luam feem ntau yog raws li hauv qab no:
Cov tshuaj tiv thaiv acetylene: los ntawm cov tshuaj tiv thaiv arylation thiab acetylenylation cov tshuaj tiv thaiv ntawm lub nplhaib benzene, lub nplhaib benzene thiab pawg acetylene txuas nrog los npaj phenylacetylene.
Enol rearrangement cov tshuaj tiv thaiv: Lub enol ntawm lub nplhaib benzene yog reacted nrog acetylenol, thiab cov rearrangement cov tshuaj tiv thaiv tshwm sim los tsim phenylacetylene.
Alkylation cov tshuaj tiv thaiv: lub nplhaib benzene muab tso rau
