Qhov sib txawv tseem ceeb ntawm methane thiab methanol yog tias methane yog qhov yooj yim tshaj plaws aliphatic hydrocarbon thiab yog ib feem ntawm cov pa roj carbon monoxide, hos methanol yog cov cawv aliphatic yooj yim tshaj plaws thiab tuaj yeem tsim los ntawm cov pa roj carbon monoxide.
Txawm hais tias cov ntsiab lus methane thiab methanol suab zoo ib yam, lawv yog cov sib txawv kiag li. Methane yog ib qho alkane, thaum methanol yog cawv. Txawm li cas los xij, lawv yog cov sib txuas yooj yim tshaj plaws ntawm lwm cov tswv cuab ntawm lawv cov kev sib raug zoo. Methane yog ib qho alkane uas muaj cov tshuaj formula CH4, hos methanol yog cov organic chemical compound uas muaj cov tshuaj formula CH3OH.
Methane yog dab tsi?
Methane yog alkane muaj cov tshuaj formula CH4. Qhov no compound yog ib qho loj tsev cog khoom gas. Kev tsim thiab kev thauj mus los ntawm cov thee, cov pa roj carbon monoxide, thiab roj yog qhov tseem ceeb uas ntxiv cov roj methane rau hauv qhov chaw. Tib neeg cov dej num xws li kev xau los ntawm cov tshuab hluav taws xob thiab kev tsim cov tsiaj nyeg kuj ua rau muaj cov ntsiab lus methane hauv huab cua.
Daim duab 01: Cov Qauv Tshuaj ntawm Methane
Ntxiv mus, methane cov ntaub ntawv nyob rau hauv tej qhov chaw xws li tej yam ntuj tso ntub dej, ntuj txheej txheem nyob rau hauv av thiab tshuaj lom neeg cov tshuaj nyob rau hauv cov huab cua. Thaum muab piv nrog cov pa roj carbon dioxide (uas yog lwm lub tsev cog khoom loj), lub neej ntawm methane hauv huab cua yog luv dua. Txawm li cas los xij, cov roj methane muaj txiaj ntsig zoo dua hauv kev cuam tshuam hluav taws xob, uas ua rau kom muaj cua sov. Yog li ntawd, methane muaj kev sib piv ntau dua li cov pa roj carbon dioxide.
Methanol yog dab tsi?
Methanol yog ib qho tshuaj lom neeg muaj tshuaj lom neeg muaj cov tshuaj formula CH3OH. Nws tseem hu ua methyl cawv. Nws yog cov cawv uas yooj yim tshaj plaws hauv cov cawv series ntawm cov tshuaj. Nws muaj ib pawg methyl txuas mus rau ib pawg hydroxyl. Peb tuaj yeem sau nws li MeOH.
Thaum xav txog cov khoom ntawm methanol, nws yog lub teeb, volatile, tsis muaj xim, thiab flammable kua uas muaj cov ntxhiab tsw ntxhiab uas nws zoo ib yam li cov ntxhiab ntawm ethanol. Ntxiv mus, methanol yog ib qho hnyav hnyav, thiab nws tseem hu ua ntoo cawv vim tias cov tshuaj no tau tsim nyob rau yav dhau los los ntawm kev puas tsuaj ntawm cov ntoo. Txawm li cas los xij, tam sim no, cov tshuaj no yog tsim los ntawm hydrogenation ntawm carbon monoxide.
Daim duab 02: Cov Qauv Tshuaj ntawm Methanol
Muaj ntau daim ntawv thov tseem ceeb ntawm methanol; siv nws ua cov khoom ua ntej rau kev tsim cov formaldehyde, acetic acid, methyl tert-butyl ether, methyl benzoate, anisole, peroxy acids, thiab lwm yam. Txawm li cas los xij, nws tsis suav nrog cov khoom siv vim tias kev noj cov tshuaj methanol tsawg heev tuaj yeem ua rau mus tas li. dig muag vim kev puas tsuaj ntawm lub paj hlwb.
Qhov txawv ntawm Methane thiab Methanol yog dab tsi?
Qhov sib txawv tseem ceeb ntawm methane thiab methanol yog tias methane yog qhov yooj yim tshaj plaws aliphatic hydrocarbon thiab nws yog ib feem ntawm cov nkev ntuj, hos methanol yog qhov yooj yim tshaj plaws aliphatic cawv, thiab peb tuaj yeem tsim methanol los ntawm cov nkev ntuj. Ntxiv mus, thaum methane tshwm sim raws li ib tug roj, methanol tshwm sim raws li ib tug kua. Tsis tas li ntawd, methane yog alkane, thaum methanol yog cawv. Tsis tas li ntawd, methane yog lub tsev cog khoom roj, tab sis methanol tsis muaj kev koom tes ncaj qha rau lub tsev cog khoom.
Cov hauv qab no qhia txog qhov sib txawv ntawm methane thiab methanol hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Methane vs Methanol
Methane thiab methanol yog cov sib xyaw yooj yim tshaj plaws ntawm lwm cov tswv cuab ntawm lawv cov kab sib txuas. Qhov sib txawv tseem ceeb ntawm methane thiab methanol yog tias methane yog qhov yooj yim tshaj plaws aliphatic hydrocarbon thiab nws yog ib feem ntawm cov pa roj carbon monoxide, qhov methanol yog cov cawv aliphatic yooj yim tshaj plaws, thiab peb tuaj yeem tsim methanol los ntawm cov nkev ntuj.
