Lo lus nug "tuaj yeem acetone yaj yas?" yog ib qho ib txwm muaj, feem ntau tau hnov ​​hauv tsev neeg, kev cob qhia, thiab cov voj science. Lo lus teb, raws li nws hloov tawm, yog ib qho nyuaj, thiab kab lus no yuav delve rau hauv cov ntsiab cai siv tshuaj thiab cov tshuaj tiv thaiv uas tsis muaj qhov tshwm sim no.

Acetoneyog cov organic yooj yim uas yog cov tsev neeg Ketone. Nws muaj cov tshuaj noj tshuaj c3h6o thiab yog cov paub zoo rau nws lub peev xwm los yaj qee hom yas. YAS, ntawm qhov tod tes, yog ib lo lus uas npog ntau yam ntawm cov txiv neej-ua cov ntaub ntawv. Lub peev xwm ntawm acetone rau yaj yas yog nyob ntawm seb hom yas koom nrog.

Thaum acetone tuaj rau hauv kev sib cuag nrog qee hom yas, tshuaj lom neeg raug tshwm sim. Cov yas molecules tau nyiam rau acetone molecules vim lawv lub ncov qaumteb qabteb. Qhov kev nyiam ua no ua rau cov yas ua liquefied, ua rau "yaj" nyhuv. Txawm li cas los xij, nws yog ib qho tseem ceeb kom nco ntsoov tias qhov no tsis yog qhov tseeb melting txheej txheem tab sis es tsis muaj tshuaj lom neeg sib tham.

Qhov tseem ceeb tshaj plaws ntawm no yog polarity ntawm cov molecules koom nrog. Nchoxules polen, xws li acetone, muaj qee qhov zoo thiab qee qhov tsis zoo them rau hauv lawv cov qauv. Qhov no tso cai rau lawv los cuam tshuam thiab sib raug zoo polar cov tshuaj zoo li qee hom yas. Los ntawm kev sib cuam tshuam no, yas ntawm cov qauv molecular muaj kev cuam tshuam, ua rau nws pom meej "melting".

Tam sim no, nws tseem ceeb kom paub qhov txawv ntawm ntau hom yas thaum siv acetone raws li cov kuab tshuaj. Thaum qee qhov plastics zoo li polyvinyl chloride (PVC) thiab polyethylene (PE) yog qhov ua tau zoo rau acetone (PP) thiab polyethylene terephthalate (tsiaj) tsis tshua muaj tshwm sim. Qhov sib txawv no hauv kev sib txawv yog vim cov qauv sib txawv thiab polarities ntawm txawv plastics.

Ntev nthuav tawm ntawm cov yas rau acetone tej zaum yuav ua rau muaj kev puas tsuaj lossis kev poob qis ntawm cov khoom. Qhov no yog vim tias cov tshuaj lom neeg ntawm acetone thiab yas yuav hloov cov qauv molecular ntawm tom kawg, ua rau cov kev hloov pauv ntawm nws lub cev.

Acetone muaj peev xwm "yaj" yas yog los ntawm cov tshuaj lom neeg ntawm lub ncov qaumteb qab zib molecules thiab qee hom polar yas. Cov tshuaj tiv thaiv no cuam tshuam cov yas qauv molecular, coj mus rau nws li qub liquefaction. Txawm li cas los xij, nws yog ib qho tseem ceeb kom nco ntsoov tias ntev nthuav tawm rau acetone tej zaum yuav ua rau muaj kev puas tsuaj lossis kev tsis txaus ntseeg ntawm cov khoom siv yas.
