Qhov sib txawv tseem ceeb ntawm butane thiab butene yog tias butane tsis muaj ob lossis peb npaug ntawm cov pa roj carbon atoms whereas butene muaj ob daim ntawv cog lus ntawm carbon atoms.
Butane thiab butene yog cov organic tebchaw uas muaj plaub carbon atoms ib molecule. Tab sis lawv muaj qhov sib txawv ntawm lawv cov qauv tshuaj xws li lawv cov tshuaj sib txuas thiab ntau cov hydrogen atoms. Yog li ntawd, lawv muaj cov tshuaj lom neeg thiab lub cev sib txawv thiab.
YButane yog dab tsi?
Butane yog cov organic compound uas muaj cov tshuaj formula C4H10 Nws yog alkane; Yog li, nws yog ib qho saturated compound. Yog li ntawd, tsis muaj ob los yog triple bonds ntawm lub atoms ntawm no molecule. Nws tshwm sim raws li cov pa roj ntawm chav tsev kub thiab siab. Cov tshuaj no muaj plaub carbon atoms thiab 10 hydrogen atoms. Cov atoms no muaj nyob rau hauv ib tug linear qauv los yog ib tug branched qauv. Peb hu cov qauv linear li "n-butane" thiab cov qauv branched li "isobutene". Txawm li cas los xij, raws li IUPAC nomenclature system, lo lus butane yog hais txog cov kab ntawv. Isobutene muaj ib ceg methyl txuas nrog peb-carbon qaum.
Daim duab 01: Cov Qauv Tshuaj ntawm n-butane
Cov molar loj ntawm cov roj no yog 58.12 g / mol. Nws yog xim tsis muaj roj. Nws muaj cov ntxhiab tsw zoo li roj av. Lub melting thiab boiling ntsiab lus yog -134 ° C thiab 1 ° C feem. Ntxiv rau qhov ntawd, cov pa roj no yog cov pa taws kub heev thiab yooj yim liquefied gas. Thaum liquefied, nws sai vaporizes ntawm chav tsev kub. Thaum muaj oxygen txaus, cov roj no hlawv, muab carbon dioxide thiab dej vapor. Tab sis yog tias cov pa oxygen tsawg, nws tsim carbon soot thiab carbon monoxide ib yam nkaus; vim tsis tiav combustion.
Thaum xav txog kev siv butane, peb tuaj yeem siv nws rau kev sib xyaw roj av, ua roj roj, ua cov tshuaj tsw qab extraction hnyav, ua cov khoom noj rau kev tsim cov ethylene, ua cov khoom xyaw rau kev tsim cov roj hmab hluavtaws, thiab lwm yam..
YButene yog dab tsi?
Butene yog ib qho organic compound uas muaj cov tshuaj formula C4H8 "Butylene" yog ib lub ntsiab lus rau tib lub ntsiab lus. Cov tshuaj no muaj plaub carbon atoms thiab 8 hydrogen atoms. Muaj ob daim ntawv cog lus ntawm ob lub pa roj carbon atom. Yog li ntawd, nws yog ib tug unsaturated compound. Nws poob rau hauv qeb ntawm alkenes. Nws yog cov roj tsis muaj xim ntawm chav tsev kub thiab siab. Peb tuaj yeem pom cov roj no ua cov khoom me me hauv cov roj av. Yog li, peb tuaj yeem tau txais cov khoom sib xyaw no los ntawm kev sib tsoo catalytic hauv lub refinery.
Daim duab 02: (2Z)-but-2-ene Isomer ntawm Butene
Vim muaj ob daim ntawv cog lus, qhov sib xyaw no muaj isomers. Muaj plaub lub isomers loj; Lawv yog, But-1-ene, (2Z)-but-2-ene, (2E)-but-2-ene thiab 2-methylprop-1-ene (isobutylene). Tag nrho cov isomers no muaj nyob ua pa. Peb tuaj yeem ua kua dej los ntawm ob txoj kev; peb tuaj yeem txo qhov kub lossis nce siab. Cov roj no muaj cov ntxhiab tsw txawv. Ntxiv mus, lawv yog cov heev flammable. Qhov ob daim ntawv cog lus ua rau cov tebchaw no muaj zog dua li cov alkanes uas muaj cov pa roj carbon zoo sib xws. Thaum xav txog cov kev siv ntawm qhov sib xyaw no, peb tuaj yeem siv lawv ua monomers hauv kev tsim cov polymers, hauv kev tsim cov roj hmab hluavtaws, hauv kev tsim cov HDPE thiab LLDPE, thiab lwm yam.
Qhov txawv ntawm Butane thiab Butene yog dab tsi?
Butane yog cov organic compound uas muaj cov tshuaj formula C4H10 thiab butene yog cov organic compound uas muaj cov tshuaj formula C 4H8 Ob qho no yog cov organic tebchaw uas muaj plaub lub atoms thiab cov lej sib txawv ntawm hydrogen atoms. Qhov tseem ceeb, qhov sib txawv tseem ceeb ntawm butane thiab butene yog nyob rau hauv lawv cov qauv tshuaj. Ntawd yog, ob daim ntawv cog lus muaj nyob hauv butene, tab sis tsis muaj nyob hauv butane. Tsis tas li ntawd, qhov no ua rau butene ntau reactive thaum muab inertness rau butane. Ntxiv mus, butene muaj plaub isomers sib txawv thaum butane muaj ob isomers nkaus xwb.
Cov ntawv qhia hauv qab no nthuav tawm cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm butane thiab butenein tabular daim ntawv.
Summary – Butane vs Butene
Butane thiab butene yog cov organic tebchaw uas muaj nyob hauv cov pa hauv chav tsev kub thiab siab. Qhov sib txawv tseem ceeb ntawm butane thiab butene yog tias butane tsis muaj ob lossis triple daim ntawv cog lus ntawm carbon atoms whereas butene muaj ob daim ntawv cog lus ntawm carbon atoms.
