Qhov sib txawv tseem ceeb ntawm xylene thiab acetone yog xylene yog cov kuab tshuaj pheej yig thiab tsis tshua muaj tshuaj lom, qhov acetone yog ib qho kim thiab hnyav hnyav dua.
Ob leeg xylene thiab acetone yog qhov tseem ceeb ua cov kuab tshuaj hauv cov chaw kuaj tshuaj. Txawm li cas los xij, lawv yog ob qhov sib txawv, thiab lawv cov khoom kuj txawv ntawm ib leeg.
YXylene yog dab tsi?
Xylene yog cov organic compound uas muaj cov tshuaj formula (CH 3)2C6 H4 Peb tuaj yeem hu nws ua dimethylbenzene vim nws muaj benzene nrog ob pawg methyl txuas. Tsis tas li ntawd, qhov sib xyaw no tshwm sim hauv ib qho ntawm peb isomers uas nws txoj haujlwm ntawm methyl pawg ntawm lub nplhaib benzene txawv ntawm ib leeg. Tag nrho peb cov isomers no tshwm sim raws li cov kua dej tsis muaj xim, flammable; Ntau qhov tseeb, qhov sib xyaw ntawm cov isomers no hu ua "xylenes".
Daim duab 01: Isomers ntawm Xylene
Peb tuaj yeem tsim cov khoom sib xyaw no los ntawm kev hloov pauv catalytic thaum lub sijhawm roj av refining lossis los ntawm cov pa roj carbonization thaum lub sijhawm tsim cov roj coke. Txawm li cas los xij, hauv kev lag luam, xylene ntau lawm yog ua los ntawm methylation ntawm toluene thiab benzene.
Xylene yog cov kuab tshuaj tsis muaj polar. Nws yog, txawm li cas los xij, kim thiab sib piv tshuaj lom. Qhov tsis muaj polar xwm yog vim qhov sib txawv ntawm electronegativity tsawg ntawm C thiab H. Yog li ntawd, xylene nyiam yaj lipophilic tshuaj zoo.
Acetone yog dab tsi?
Acetone yog cov organic compound uas muaj cov tshuaj formula (CH3)2CO. Nws tshwm sim raws li ib tug tsis muaj kob thiab flammable kua uas yog volatile heev. Nws yog qhov yooj yim tshaj plaws thiab tsawg tshaj plaws ketone. Qhov hnyav ntawm molar yog 58.08 g / mol. Nws muaj pungent, irritating tsw, tab sis peb muaj peev xwm txhais tau tias nws yog ib tug floral, dib-zoo li tsw. Nws yog miscible nrog dej. Tsis tas li ntawd, qhov sib xyaw ua ke no feem ntau yog cov kuab tshuaj polar. Lub polarity yog vim qhov siab electronegativity sib txawv ntawm carbon thiab oxygen atoms ntawm carbonyl pawg. Txawm li cas los xij, nws tsis yog ntau polar. Yog li, nws tuaj yeem yaj ob qho tib si lipophilic thiab hydrophilic tshuaj.
Daim duab 02: Cov qauv tshuaj ntawm Acetone
Peb lub cev tuaj yeem tsim cov acetone hauv cov txheej txheem metabolic ib txwm thiab tseem muab pov tseg los ntawm lub cev los ntawm cov txheej txheem sib txawv. Hauv kev lag luam nplai, txoj kev tsim khoom suav nrog kev tsim khoom ncaj qha lossis tsis ncaj los ntawm propylene. Cov txheej txheem ntau yog txheej txheem cumene.
Qhov txawv ntawm Xylene thiab Acetone yog dab tsi?
Xylene yog ib qho organic compound uas muaj cov tshuaj formula (CH 3)2C6 H4 hos Acetone yog cov organic compound uas muaj cov tshuaj formula (CH3)2CO. Qhov sib txawv tseem ceeb ntawm xylene thiab acetone yog xylene yog ib qho pheej yig thiab tsis tshua muaj kuab lom, thaum acetone yog ib qho kim thiab hnyav hnyav dua. Ntxiv mus, xylene tsis yog polar, thiab acetone tsawg dua polar; Yog li ntawd, xylene tuaj yeem yaj cov tshuaj lipophilic, tab sis acetone tuaj yeem yaj ob qho lipophilic thiab hydrophilic tshuaj.
Hauv qab infographic qhia txog qhov sib txawv ntawm xylene thiab acetone.
Summary – Xylene vs Acetone
Xylene yog ib qho organic compound uas muaj cov tshuaj formula (CH 3)2C6 H4 hos Acetone yog cov organic compound uas muaj cov tshuaj formula (CH3)2CO. Qhov sib txawv tseem ceeb ntawm xylene thiab acetone yog xylene yog ib qho pheej yig thiab tsis tshua muaj kuab tshuaj lom, whereas acetone yog ib qho kim thiab hnyav hnyav dua.
