Qhov sib txawv tseem ceeb ntawm acetone thiab methylated ntsuj plig yog tias acetone yog cov kua tsis muaj xim, hos tus ntsuj plig methylated yog cov tshuaj pleev xim violet.
Acetone thiab methylated ntsuj plig yog ob qho kev daws teeb meem sib txawv. Qhov ntawd yog; acetone yog qhov yooj yim tshaj plaws ketone, thiab nws tshwm sim raws li cov kua tsis muaj xim uas muaj purity siab. Ntawm qhov tod tes, cov methylated dab hais txog ethanol uas muaj methanol, uas yog tshuaj lom rau haus.
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 ib tug pungent, irritating tsw thiab yog miscible nrog dej. Tsis tas li ntawd, qhov sib xyaw 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 lipophilic thiab hydrophilic tshuaj.
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. Tsis tas li ntawd, nyob rau 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.
Dab tsi yog Methylated Spirits?
A methylated ntsuj plig yog ib qho cawv uas tsis haum rau haus vim muaj methanol. Feem ntau, manufacturers ua rau nws tsis haum rau haus los ntawm kev ntxiv methanol (10%). Feem ntau, cov tshuaj no muaj qee cov pyridine thiab violet dye ib yam nkaus. Lub npe uas peb siv rau cov tshuaj no yog denatured cawv.
Ntxiv mus, cov additives hauv cov tshuaj no ua rau nws lom. Nws kuj muaj qhov tsis zoo thiab muaj ntxhiab tsw phem. Qee zaum, cov tuam txhab lag luam nyiam ntxiv cov zas xim, piv txwv li violet dye, kom paub qhov txawv ntawm cov cawv cawv los ntawm kev haus cawv. Kev siv loj ntawm cov tshuaj no yog ua kuab tshuaj. Nws kuj tseem siv tau ua roj.
Qhov txawv ntawm Acetone thiab Methylated Spirits yog dab tsi?
Ob leeg acetone thiab methylated ntsuj plig yog cov organic tebchaw. Tab sis, qhov sib txawv tseem ceeb ntawm acetone thiab methylated ntsuj plig yog acetone yog cov kua tsis muaj xim, hos tus ntsuj plig methylated yog cov xim violet. Ntxiv mus, acetone yog cov kua ntshiab, tab sis methylated dab muaj ethanol uas muaj 10% methanol thiab lwm yam additives xws li dye.
Tsis tas li ntawd, acetone yog qhov yooj yim tshaj plaws ketone, thiab nws tshwm sim raws li cov kua tsis muaj xim uas muaj purity siab. Ntawm qhov tod tes, methylated dab hais txog ethanol uas muaj methanol, uas yog tshuaj lom rau haus. Tsis tas li ntawd, lwm qhov sib txawv ntawm acetone thiab methylated ntsuj plig yog lawv siv. Acetone yog siv los ua cov kuab tshuaj thiab ua cov tshuaj reactant rau cov txheej txheem sib txawv hauv cov organic chemistry, hos methylated spirits yog siv los ua cov kuab tshuaj thiab roj.
Cov lus qhia hauv qab no qhia txog qhov sib txawv ntawm acetone thiab methylated dab.
Summary – Acetone vs Methylated Spirits
Yeej, ob qho tib si acetone thiab methylated ntsuj plig yog cov organic tebchaw. Txawm li cas los xij, acetone yog qhov yooj yim tshaj plaws ketone, thiab nws tshwm sim raws li cov kua tsis muaj xim uas muaj purity siab. Ntawm qhov tod tes, methylated dab hais txog ethanol uas muaj methanol, uas yog tshuaj lom rau haus. Yog li, qhov sib txawv tseem ceeb ntawm acetone thiab methylated ntsuj plig yog acetone yog cov kua tsis muaj xim, hos tus ntsuj plig methylated yog cov xim violet. Yog li, nws yooj yim heev los txheeb xyuas qhov sib txawv ntawm acetone thiab methylated ntsuj plig thaum xub thawj siab.
