Qhov Tseem Ceeb Qhov txawv - Acetylene vs Ethylene
Qhov txawv ntawm acetylene thiab ethylene yog tias acetylene muaj triple daim ntawv cog lus ntawm ob lub atoms carbon whereas ethylene muaj ob daim ntawv cog lus ntawm ob lub atoms.
Cov npe acetylene thiab ethylene suab zoo ib yam, tab sis lawv yog cov sib txawv hydrocarbon tebchaw. Txawm li cas los xij, lawv kuj muaj qee qhov sib xws. Kab lus no piav qhia txog qhov zoo sib xws thiab qhov sib txawv ntawm acetylene thiab ethylene.
Acetylene yog dab tsi?
Acetylene yog cov organic compound uas muaj cov tshuaj formula C2H2 Tsis tas li ntawd, nws yog qhov yooj yim alkyne ntawm hydrocarbons. Ib qho alkyne yog ib qho kev sib txuas nrog triple daim ntawv cog lus ntawm ob lub atoms carbon. Yog li ntawd, acetylene muaj triple daim ntawv cog lus ntawm ob lub atoms nws muaj. Muaj ob daim ntawv cog lus pi thiab ib daim ntawv cog lus ntawm cov pa roj carbon atom. Lub molecule muaj ib tug linear geometry vim hais tias ib tug carbon atom muaj peev xwm tsim tsuas yog plaub covalent bonds (acetylene muaj ib tug triple daim ntawv cog lus thiab ib daim ntawv cog lus, C-H, uas ua rau cov molecule linear). Yog li ntawd, cov pa roj carbon atoms ntawm acetylene molecule yog sp hybridized.
tshuaj muaj txiaj ntsig ntawm Acetylene
Qee cov lus tseeb txog acetylene yog raws li hauv qab no:
- Chemical formula=C2H2
- Molar mass=26.04 g/mol
- Lub cev lub cev ntawm chav tsev kub=nws tsis muaj xim tsis muaj roj
- Sau=tsis muaj ntxhiab
- melting point=-80.8°C
- Boiling point=-84°C
- Solubility hauv dej=me ntsis soluble
- IUPAC lub npe=Ethyne
Ntxiv mus, acetylene tsis muaj nyob hauv cov kua hauv huab cua. Yog li, nws tsis muaj qhov tseeb melting point. Lub melting kub uas tau muab los saum toj no yog qhov tseeb triple point ntawm acetylene. Yog li ntawd, cov khoom ntawm acetylene undergo sublimation ntau dua li melting. Nyob ntawd, cov khoom acetylene hloov mus ua vapor.
Daim duab 01: Siv cov nplaim hluav taws xob oxy-acetylene
Daim ntawv thov loj ntawm acetylene yog nyob rau hauv cov txheej txheem vuam. Cov nplaim hluav taws xob oxy-acetylene yog cov nplaim hluav taws kub uas tseem ceeb hauv kev vuam thiab txiav. Peb tuaj yeem tsim cov nplaim hluav taws no los ntawm kev sib xyaw ntawm acetylene nrog oxygen.
Ethylene yog dab tsi?
Ethylene yog cov organic compound uas muaj cov tshuaj formula C2H4 Muaj ob lub atoms sib koom ua ke ntawm ob daim ntawv cog lus (pib daim ntawv cog lus thiab sigma daim ntawv cog lus). Yog li ntawd, ethylene molecule muaj ob sp2 hybridized carbon atoms. Txij li thaum cov pa roj carbon atom muaj peev xwm tsim tau plaub daim ntawv cog lus, muaj ob lub hydrogen atoms sib koom ua ke rau txhua cov pa roj carbon atom ntawm ib daim ntawv cog lus. Tom qab ntawd cov ethylene molecule muaj cov qauv qauv.
Daim duab 02: Cov Qauv Tshuaj ntawm Ethylene
Qee cov lus tseeb txog ethylene yog raws li hauv qab no:
- tshuaj formula=C2H4
- Molar mass=28.05 g/mol
- Lub cev lub cev ntawm chav tsev kub=nws tsis muaj xim tsis muaj roj, nplaim hluav taws kub
- Suab=tsw qab zib
- Melting point=−169.2°C
- Boiling point=−103.7°C
- Solubility hauv dej=me ntsis soluble
- IUPAC lub npe=Ethene
Qhov loj ntawm ethylene yog cov roj av thiab cov nkev ntuj. Muaj peb txheej txheem tseem ceeb siv los tsim ethylene los ntawm cov peev txheej no. Lawv yog;
- Chav tawg ntawm ethane thiab propane
- Neev tawg ntawm naphtha
- Catalytic tawg ntawm cov roj roj
Ethylene muaj qhov tseem ceeb siv los ua monomers rau kev tsim cov polymers xws li polyethylene los ntawm kev ntxiv polymerization. Polyethylene yog cov khoom ntim khoom siv. Tsis tas li ntawd, nyob rau hauv cov kab mob lom, ethylene yog ib qho tseem ceeb raws li cov tshuaj cog qoob loo vim nws txhawb nqa cov txiv hmab txiv ntoo ripening.
Dab tsi zoo sib xws ntawm Acetylene thiab Ethylene?
- Ob leeg yog cov hydrocarbons me me.
- Acetylene thiab Ethylene tsuas yog tsim los ntawm carbon atoms thiab hydrogen atoms.
- Ob leeg yog cov roj tsis muaj xim.
- Ob qho tib si Acetylene thiab Ethylene yog cov roj hluav taws kub.
- Acetylene thiab Ethylene yog cov qauv txheej txheem.
