Qhov sib txawv tseem ceeb ntawm methylacetylene thiab acetylene yog tias methylacetylene muaj ib pawg methyl txuas rau acetylene molecule, whereas acetylene yog cov organic compound uas muaj triple bonded carbon atom khub.
Methylacetylene thiab acetylene yog cov organic compounds uas muaj triple bonded carbon atoms. Cov no yog cov yooj yim alkene compounds nyob rau hauv lub alkyne series.
Methylacetylene yog dab tsi?
Methylacetylene lossis propyne yog cov organic compound uas muaj cov tshuaj formula CH3C≡CH. Nws yog qhov thib ob yooj yim alkene ntawm alkyne series. Peb tuaj yeem pom cov tshuaj lom neeg no nyob rau theem gaseous thaum nws yog ib feem ntawm MAPD roj (nrog rau propadiene - isomer ntawm propyne). Methylacetylene yog cov roj tsis muaj xim uas muaj ntxhiab tsw qab.
Daim duab 01: Cov Qauv Tshuaj ntawm Methylacetylene Molecule
Methylacetylene roj feem ntau muaj nyob rau hauv qhov sib npaug nrog propadiene, isomer ntawm methylacetylene. Qhov sib tov no hu ua MAPD gas. Hauv chav kuaj, peb tuaj yeem tsim cov tshuaj methylacetylene los ntawm kev txo 1-propanol, allyl cawv lossis acetone vapors tshaj magnesium catalyst.
Qhov no gaseous compound yog lub tsev tseem ceeb rau cov organic synthesis tshuaj. Piv txwv li, deprotonation ntawm Methylacetylene nrog n-butyllithium muab propynyllithium. Purified methylacetylene yog kim, tab sis peb tuaj yeem tsim cov roj no pheej yig hauv ntau qhov siv MAPP roj. Methylacetylene roj tuaj yeem ua raws li nucleophilic reagent thiab tau ntxiv rau carbonyl pawg, ua rau muaj cawv thiab esters. Tsis tas li ntawd, methylacetylene tuaj yeem ua rau cov roj foob pob ua ntxaij ua tau zoo.
Acetylene yog dab tsi?
Acetylene yog qhov yooj yim alkyne uas muaj cov tshuaj formula C2H2. Lub systemic IUPAC lub npe ntawm acetylene yog ethyl. Cov roj no tshwm sim raws li cov roj tsis muaj xim nyob rau hauv chav tsev kub thiab siab. Peb tuaj yeem categorize nws li hydrocarbon vim tias nws tsuas muaj cov pa roj carbon thiab hydrogen atoms nrog kev sib txuas ntawm cov pa roj carbon atoms. Cov roj acetylene yog dav siv tau zoo li roj thiab lub tsev thaiv rau kev sib txuas ntawm cov tshuaj sib txawv.
Daim duab 02: Cov Qauv Tshuaj ntawm Acetylene Molecule
Cov acetylene molecule, raws li pom nyob rau hauv daim duab saum toj no, muaj ib tug triple daim ntawv cog lus ntawm ob lub carbon atoms, uas ua rau nws categorization raws li ib tug alkyne. Tsis tas li ntawd, qhov valency ntawm txhua carbon atom nyob rau hauv no molecule yog 4. Nyob rau hauv lwm yam lus, txhua carbon atom nyob rau hauv no molecule khi rau ib hydrogen atom ntawm ib daim ntawv cog lus, uas tsis yog tsim ib tug triple daim ntawv cog lus ntawm lwm cov carbon atoms. Yog li ntawd, acetylene molecule muaj ib tug linear geometry, thiab nws muaj ib tug qauv qauv. Txhua carbon atom nyob rau hauv no molecule yog sp hybridized.
Qhov txawv ntawm Methylacetylene thiab Acetylene yog dab tsi?
Methylacetylene thiab acetylene yog cov yooj yim alkene compounds nyob rau hauv alkene series. Qhov sib txawv tseem ceeb ntawm methylacetylene thiab acetylene yog tias mthylacetylene muaj cov methyl pawg txuas nrog acetylene molecule, whereas acetylene yog cov organic compound uas muaj triple bonded carbon atom khub. Ntxiv mus, methylacetylene muaj ntxhiab tsw qab thaum acetylene muaj cov ntxhiab tsw zoo li qej.
Tsis tas li ntawd, hais txog kev tsim khoom, methylacetylene yog tsim los ntawm kev txo 1-propanol, allyl cawv lossis acetone vapors tshaj magnesium catalyst whereas acetylene ua los ntawm cov tshuaj tiv thaiv dej nrog calcium carbide, los ntawm kev hla ntawm hydrocarbon los ntawm hluav taws xob arc., thiab los ntawm ib nrab combustion ntawm methane nrog cua lossis oxygen.
Hauv qab infographic tabulates ib sab ntawm qhov sib txawv ntawm methylacetylene thiab acetylene.
Summary – Methylacetylene vs Acetylene
Methylacetylene thiab acetylene yog cov yooj yim alkene compounds nyob rau hauv alkene series. Qhov sib txawv tseem ceeb ntawm methylacetylene thiab acetylene yog tias methyacetylene muaj ib pawg methyl txuas rau acetylene molecule, whereas acetylene yog cov organic compound uas muaj triple bonded carbon atom khub. Ntxiv mus, tsis zoo li cov roj acetylene, methylacetylene tuaj yeem ua kom muaj kev nyab xeeb.
